Description
Custom High Precision PU Wheels for Measuring Devices
Why Choose This Product
Our PU wheels are designed with a precision-machined hub and a specially formulated polyurethane compound that offers Shore A 85° hardness with excellent wear resistance. This feature means the wheels maintain consistent rolling characteristics over thousands of cycles, reducing the need for frequent recalibration of your measurement devices. The benefit to your operation is higher measurement accuracy, less downtime, and lower total cost of ownership. Evidence from our in-house testing shows less than 0.02mm wear after 2000 hours of continuous use on granite reference surfaces. Additionally, the non-marking tread protects sensitive floors and measuring stages, while the sealed precision bearings prevent contamination from dust and debris. For demanding applications such as coordinate measuring machines, optical scanners, and portable inspection carts, these wheels offer a reliable, long-lasting solution.
Custom roller compounds (PU, NBR, EPDM, silicone), hardness from Shore A 20° to 98°, and surface patterns are available. Dynamic balancing tolerance ≤0.05mm reduces noise and extends bearing life. ISO9001 certified, our wheels are ideal for factory conveyors, packaging lines, logistics automation, and assembly stations.
Typical applications: Belt conveyors, roller conveyors, AGV transport systems, automated production lines, warehouse sorting equipment, food processing lines, and heavy-load transfer stations.

Ratings: 1 = low, 5 = high. Polyurethane offers the best overall performance for heavy-duty conveyor wheels – high abrasion resistance and load capacity, which directly translates to longer service life and reduced replacement frequency for your factory conveyor systems. Custom hardness from Shore 20A to 98A is available from our factory.

Production & Inventory Policy
Lead time: Actual delivery time may vary due to raw material availability, machine scheduling, and peak season fluctuations. After order confirmation, we provide the most accurate estimate and keep transparent communication.
Stock status: We generally do not hold large finished-goods inventory, but some popular standard models may have limited dynamic stock (which changes as sales and production progress). Please confirm real-time availability with our team before ordering.
Bulk & urgent orders: For mass production or tight schedules, we recommend early discussion of capacity and production planning. We will do our best to support your timeline.
Frequently Asked Questions – PU Measuring Wheels
1. Can you provide custom mounting solutions for our specific measuring device?
Yes, we offer full OEM/ODM customization for mounting holes, stud lengths, bracket designs, and wheel diameters. Our engineering team can work from your drawing or sample to create a precise fit for your equipment. This custom solution ensures seamless integration with your existing design.
2. What is the minimum order quantity for custom PU wheels?
For standard sizes and mounting, our MOQ is 50 pieces per type. For fully custom designs with new tooling, the MOQ is typically 200 pieces. We understand smaller quantities are sometimes needed for prototype or R&D projects, so please discuss your requirement with us and we will find the best approach.
3. How does the polyurethane compound improve measurement accuracy compared to rubber wheels?
Our polyurethane formulation offers consistent Shore A hardness across the entire tread, with minimal variation from temperature changes. Unlike natural rubber, PU does not develop a glazed surface over time, ensuring stable rolling friction and reducing micro-vibrations that could affect sensitive measurements. This has been verified in our lab tests on granite surface plates.
4. What are your typical delivery times for custom orders?
For custom PU wheels with existing tooling, delivery is usually 15-20 working days. For new custom designs requiring mold fabrication, please allow 25-30 working days. We always provide a confirmed schedule after order placement and keep you updated on progress.
5. Do you provide quality documentation or test reports with each batch?
Yes, every shipment includes a certificate of conformance with hardness, dimensional, and load test data. Third-party inspection reports (such as SGS or TÜV) can be arranged upon request. Our ISO9001 quality system ensures full traceability from raw material to finished wheel.
6. What are the available payment and shipping options?
We accept T/T bank transfer, L/C at sight, and for established clients, PayPal or Western Union for small orders. Shipping options include FOB Shanghai, CIF major ports, or door-to-door express for samples. Our team will recommend the most cost-effective method based on your order size and location.
