Polyurethane-coated bearings and cam followers combine a precision bearing with a resilient urethane tread. The coating can reduce noise, absorb impact, protect mating surfaces and provide controlled traction in conveyors, guides and automation equipment. Profiles include flat, crowned, V-groove and U-groove designs, with custom hardness and color options.

We can mold polyurethane directly onto customer-supplied bearings or source the bearing and deliver a complete assembly. Existing cores may be suitable for stripping and recoating after inspection. Material, dimensions and tolerances are selected from the load, speed, temperature, chemical exposure and contact-surface requirements.

Applications of Polyurethane-Coated Bearings

pu-bearing

Manufacturing and Automation

– Conveyor systems: Reduce noise and vibration while protecting tracks and conveyed products from metal-to-metal contact.

– Diverter wheels and guides: Support controlled product movement in AGVs, sorters and material-handling systems.

Automotive and Electric-Vehicle Manufacturing

– Assembly and handling equipment: Guide wheels and coated bearings support quiet, low-marking movement of components.

– Fixtures and conveyors: Custom formulations can be selected for oil, abrasion and repeated-cycle exposure.

Heavy Industry & Construction

– Excavators and cranes: Coated guide bearings and rollers can be designed for shock, contamination and repeated loading.

Agriculture

– Farm machinery: Formulations can be selected for moisture, fertilizer, oil and abrasive contamination.

Consumer Goods

– Cash-handling machines: Provide controlled traction and quiet movement in bill sorters and currency counters.

– Sporting equipment: Reduce noise and vibration in exercise machines, skate equipment and guide assemblies.

Profiles for Custom Polyurethane-Coated Bearings

1) V-groove: A V-shaped groove is molded into the polyurethane coating or machined after casting.

2) U-groove: A U-shaped groove is molded into the polyurethane coating or machined after casting.

3) Straight: A flat running surface with square edges.

4) Chamfered: The coating edges are beveled to remove sharp corners.

5) Radiused: The coating edges use a specified radius for smoother contact.

6) Crowned: The running surface has a specified crown radius to support tracking and centered contact.

Why Choose Our Polyurethane-Coated Bearings?

groove-polyurethane-bearings

– Direct manufacturer: Engineering, molding and finishing are coordinated through one supplier.

– Custom engineering: Dimensions, hardness, profile and formulation can be matched to the application, including antistatic or flame-retardant options where specified.

– Bonding control: Metal preparation, bonding systems and molding parameters are selected for the core and service conditions.

– Flexible supply: Send your preferred bearings, ask us to source them or submit used cores for recoating assessment.

– Inspection: Dimensions, coating condition, concentricity and free rotation are checked before delivery.

  • How long do polyurethane coated bearings last compared to standard metal bearings?

    They typically last 50% longer—thanks to wear-resistant urethane that shields against vibration and heavy loads.

  • What maintenance do PU coated wheels and bearings require?

    Wipe with a dry cloth to remove debris; avoid harsh solvents that damage the urethane coating.

  • Can your polyurethane coated bearings withstand extreme temperatures or chemicals?

    Yes—they work in -40°C to 120°C and resist oils, solvents, and agricultural/industrial chemicals.

  • If a bearing’s urethane coating wears down, can it be recoated instead of replaced?

    Yes—we offer recoating services for your existing bearings to save cost vs. buying new units.

  • Are you a manufacturer?

    Yes. We are manufacturer. Welcome to visit our factory.

  • Can you introduce your customized process ?

    Yes. The process includes Share needs → design & quote → prototype (opt) → production → delivery.

  • How do you control your product quality?

    We have 10 inspectors to carry out raw material inspection, process control ,first article inspection and final inspection.

  • How do you monitor the production process to avoid delayed delivery?

    We use the ERP system to execute orders, and can check the order status and expected delivery time at any time.

  • What is warranty of products?

    All of products with 3-6 months guarantee (except very frequently wearing parts).

  • How do you deal with after sales service?

    We will response in 24 hours with solutions such as replacement or reworking.

  • How do you deal wtih customers' molds?

    We have dedicated personnel to sort out and maintain molds regularly.

  • What about the lifespan of molds?

    20,000 times for compressions molds and 30,000 time for casting molds.

  • How long can you keep customers' molds for free?

    Due to the large quantity of molds, we can keep the molds for free for 2 to 3 years even if no order.

  • If the molds are damaged or reach the lifespan , who will be responsible for it ?

    Customers only need to pay mold cost once. We will cover the cost if molds are damaged or reach the lifespan.
