Thermoplastic polymer plain bearings and sleeve bearings, especially those lined with (Polytetrafluoroethylene), offer exceptional properties for a wide range of applications. , commonly known as ptfe, is renowned for its excellent chemical resistance, low friction coefficient, and high temperature tolerance.
When wrapped or lined within a thermoplastic polymer matrix, these bearings exhibit improved wear resistance, longer service life, and the ability to handle higher loads and speeds compared to traditional metal or plastic bearings. The thermoplastic polymer provides a strong base for the lining, ensuring dimensional stability and resistance to deformation under heavy loads.
The combination of thermoplastic polymer and also allows for bearings that are lightweight, corrosion-resistant, and suitable for use in both dry and lubricated environments. This versatility makes them ideal for applications in the automotive, aerospace, medical, and food processing industries, among others.
The installation and maintenance of thermoplastic polymer plain bearings and sleeve bearings lined with are typically straightforward, further enhancing their appeal for use in various industrial settings. With their superior performance and durability, these bearings are becoming increasingly popular as a reliable and cost-effective alternative to traditional bearing materials.
Carbon Steel self-lubricating bearings used high quality low-carbon steel plate as base, sintered porous bronze as its interlayer and the Compound of and Lead as its surface.
Our lined wrapped bearings have been developed for high duty, oil lubricate applications. Such applications include, but are not limited to:
Our VIIPLUS range of lined wrapped bearings is suitable for dry running, low friction, low wear applications. These wrapped bearings have excellent sliding characteristics forming a transfer film that can protect the mating metal surface.
We are able to offer lined wrapped bearings in metric plain, imperial plain, metric flanged, metric washers, imperial washers, metric strip and imperial strip. Special sizes can be produced to customer requirements,

VSB-40 low friction bushings offer good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Very good performance in lubricated applications
· Good performance in greased applications
· Suitable for linear, oscillating and rotating movements
Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surfaces, suitable for rotating and oscillating movement, high chemical resistance, low absorption of water and swelling. The VSV-40 improved the friction and much good wear resistance over the common CSB-10 range under lubricated operation.
1. /Polymer fibres mixture thickness 0.01~0.03mm. Lead-free bearing layer provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the mixture.
3. Steel backing, provides high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.
