PTC ASIA 2026: How to Source Power Transmission Components

Selecting a bearing, gearbox, hydraulic valve or electric motor rarely begins with the supplier’s catalogue number. The real starting point is the machine duty: load, motion, environment, operating time, control response, service life and the consequences of a failure. PTC ASIA 2026 brings the component technologies behind that duty to the Shanghai New International Expo Centre from 3 to 6 November.

The show covers fluid power, sealing, gears, chains, belts, couplings, brakes, motors, bearings, linear motion, springs and industrial subcontracting. It can support a replacement-component search, a new machine design or a supplier-localisation programme, but each mission needs a different comparison basis. This guide turns the fair into a component qualification route and uses concurrent CeMAT ASIA only where seeing the end application adds useful evidence.

Convert machine duty into a supplier brief

Begin with the assembly in which the component will operate. Provide a drawing or system diagram where confidentiality allows, then describe:

continuous, intermittent, peak and emergency loads;
speed, torque, force, pressure, flow or travel range;
duty cycle, starts, stops, reversals and expected operating hours;
shock, vibration, misalignment and mounting constraints;
temperature, dust, moisture, corrosion, washdown or clean-environment conditions;
accuracy, repeatability, backlash, response or leakage limits;
control, sensor, feedback and machine-network interfaces;
target life, maintenance interval and acceptable replacement time;
destination-market technical, safety and documentation requirements.

This brief lets buyers compare proposed components by function rather than by marketing category. It also shows where a standard product is sufficient, where a configured assembly is needed and where the supplier must participate in system design.

For replacement sourcing, add the installed part, failure history, measured operating conditions and any modifications made since the machine was commissioned. A dimensionally interchangeable item can behave differently if materials, clearances, sealing, lubrication, heat dissipation or control characteristics change.

Divide the fair by engineering problem

Hydraulic, pneumatic and sealing systems

PTC ASIA’s official fluid-power scope includes pumps, motors, cylinders, valves, power units, accumulators, filters, lubrication systems, heat exchangers, hoses, fittings, pneumatic preparation and control, actuators, seals and test equipment.

For hydraulic candidates, define working and peak pressure, flow profile, fluid, cleanliness target, temperature, cycle, required response and energy use. Ask the supplier to show how the pump, valve, actuator, filtration, cooling and controls work together. A component may meet its nominal rating while the complete circuit still creates heat, pressure loss, noise or unstable motion.

For pneumatics, compare air quality, operating pressure, flow, speed, cushioning, leakage, valve response and compressed-air demand at the actual cycle. The lowest component price can be outweighed by air consumption, short seal life or difficult maintenance across a large installed base.

Seal selection should follow pressure, speed, motion type, surface condition, fluid compatibility, temperature and contamination. Bring the groove or mating-surface information and explain the observed failure mode. Asking for a material name alone gives the supplier too little context to distinguish extrusion, wear, hardening, chemical attack, poor lubrication or installation damage.

Gears, reducers and mechanical transmission

The show’s mechanical scope covers gears and gearboxes, chain and belt drives, couplings, brakes, springs, transmission components, manufacturing solutions and test equipment. Build comparisons around the torque-speed profile and complete load spectrum rather than one rated value.

For gearboxes and geared motors, record ratio, input and output conditions, service factor, acceleration, shock, reversing, mounting, shaft loads, backlash, efficiency, temperature, noise and lubrication. Clarify whether the supplier selects the unit, verifies the application and accepts responsibility for the proposed configuration, or supplies only against a buyer-defined model.

For chains and belts, include centre distance, sprocket or pulley geometry, load variation, speed, tensioning, lubrication, contamination and access for replacement. Couplings and brakes need the relevant inertia, alignment, torsional behaviour, stopping duty and fail-safe requirement. These details make comparisons more useful than a table of nominal sizes.

Bearings and linear motion

PTC ASIA lists rolling bearings, specialised and non-standard bearings, rings, balls, cages, seals, related shafts and components, linear-motion systems, bearing-production equipment and inspection instruments.

Provide load direction and spectrum, speed, shaft and housing fits, alignment, stiffness, accuracy, temperature, lubrication, sealing and expected life. For linear guides or screw systems, add travel, acceleration, moment loads, mounting surface, preload and positioning requirements. Ask how the supplier calculated the selection and which assumptions dominate the result.

The fair can also serve buyers sourcing bearing rings, cages, balls or manufacturing equipment. That is a different mission from buying a finished bearing. Separate the drawing, material, heat treatment, precision class, inspection plan and batch requirement so supplier roles remain clear.

Motors and electric drives

The official 2026 material includes industrial and servo motors, frequency converters, electric drives and electromagnetic equipment. Define the load’s torque-speed curve, starts and stops, overload, voltage and frequency, control mode, feedback, brake, cooling, mounting, enclosure and communication needs.

A higher-efficiency motor does not automatically create the lowest system energy use if it is incorrectly sized or paired with an unsuitable drive and transmission. Ask suppliers to explain the operating points used for efficiency, thermal and lifetime calculations. For servo applications, include inertia matching, motion profile, settling, encoder and control-loop expectations.

Identify the supplier role before comparing prices

PTC ASIA may present component manufacturers, system suppliers, distributors, engineering firms and subcontractors in adjacent halls. Establish the role early:

Does the company design and manufacture the offered product?
Which plant, legal entity and quality system apply to the proposed item?
Is the quotation for a standard component, configured assembly or engineered system?
Who selects the product and carries application responsibility?
Which parts or processes are outsourced?
Who provides drawings, software, certificates, test data and change notices?
Where are stock, service, repairs and technical support located for the buyer’s market?

A distributor can be the right partner when availability, multi-brand integration and local support dominate. A manufacturer may be stronger for custom engineering, production evidence or long-term design control. The comparison should reflect the role the buyer actually needs.

A four-day component-sourcing route

3 November — establish technical families

Start with the component groups that carry the greatest machine risk or cost. Give each candidate the same duty brief and record the proposed series, size and assumptions. Do not spend the first day resolving every commercial detail; use it to expose different technical routes and missing information.

End the day with a shortlist by component family and a list of questions that require product specialists rather than sales introductions.

4 November — compare calculations and configuration

Return for application reviews. Ask suppliers to walk through selection calculations, limits and derating. Compare what is included around the main component: sensors, manifolds, cooling, filters, controls, mounting parts, cables, connectors, lubrication, commissioning tools or software.

For a machine platform with several sizes, test the selection against more than one duty point. This shows whether the proposed family can cover future variants without unnecessary redesign or inventory growth.

5 November — examine quality, service and change control

Move from selection to supply continuity. Discuss drawing and revision control, critical characteristics, inspection, traceability, sub-supplier management, production change notification, warranty analysis, spare parts and repair. For safety- or uptime-critical components, identify the evidence needed before approval and the response expected after a failure.

Buyers localising an existing part can use the day to compare sample and validation plans. Agree which dimensions, material properties, performance tests and endurance conditions must match the current design, and which changes require the machine owner or engineering authority to approve them.

6 November — close the follow-up plan

The official schedule closes at 2:00 pm on the final day. Reserve it for planned second meetings, missing documents and agreement on the next evidence step. A useful output is a component-by-component action register showing owner, data required, sample route, test method, quotation revision and decision date.

Add CeMAT ASIA for application context, not a second component search

CeMAT ASIA 2026 takes place on the same dates at the same venue. Its focus is intralogistics: forklifts, conveyors, sortation, automated storage, warehouse robots, controls, packaging and logistics software. It gives selected PTC buyers a way to see how motors, reducers, bearings, chains, hydraulics and controls enter complete handling systems.

The extension is most useful for component manufacturers, OEM engineering teams and buyers developing conveyors, cranes, storage and retrieval systems, mobile robots, forklifts or other material-handling equipment. Use CeMAT to observe integration demands and identify application partners, then take the resulting questions back to the PTC shortlist.

Machine builders outside intralogistics, maintenance teams with a defined replacement task and buyers focused on one fluid-power or bearing category may obtain little extra value. The two fairs share an industrial network, but they solve different procurement problems and do not need equal time.

Plan samples, tests and factory follow-up

The next step should match the component risk. A catalogue confirmation may be enough for a low-risk standard item. A configured drive or hydraulic assembly may need design review and a functional sample. A new supplier for a high-duty bearing, gearbox, brake or safety-related actuator may require material, process, endurance and application evidence before approval.

When a factory visit is justified, confirm that the site performs the relevant design, production and test work. Focus on the processes that determine the proposed component: machining, heat treatment, surface finishing, cleanliness, assembly, calibration, end-of-line test, software loading or repair. A general tour adds less than a review tied to the buyer’s drawing and validation plan.

Keep first-article, pilot and production approval separate. A sample can show that one part meets selected checks; it does not establish stable serial supply. Define the later controls, change-notification route and response to field failures while technical and commercial teams are still aligned.
