The Metal-Polymer Bronze-Backed PTFE Plain Bearing is a unique and advanced bearing solution that offers exceptional strength and durability. Combining the robustness of a bronze backing with the slippery smoothness of Polytetrafluoroethylene (PTFE), this bearing is designed to handle heavy loads and demanding applications with ease.
The bronze backing provides the bearing with a solid foundation, ensuring stability and rigidity. Bronze is known for its excellent wear resistance and strength, making it a reliable material for supporting and protecting the bearing surface.
The PTFE liner, on the other hand, offers unparalleled lubricity and low friction properties. PTFE is a synthetic fluoropolymer that is renowned for its non-stick and self-lubricating characteristics. This allows the bearing to operate smoothly, even in the absence of external lubricants, reducing wear and extending the bearing's service life.
The combination of these two materials creates a bearing that is not only strong but also efficient and reliable. The high strength of the bronze backing ensures that the bearing can withstand heavy loads and demanding operating conditions, while the PTFE liner ensures smooth and low-friction operation.
Overall, the Metal-Polymer Bronze-Backed PTFE Plain Bearing is an excellent choice for applications that require a bearing with high strength, durability, and smooth operation. Whether it's used in automotive systems, industrial machinery, or any other demanding application, this bearing is sure to deliver superior performance and reliability.

Standard and custom Plain Bearings made for you.

Maintenance free thus lower your cost.

As a manufacturer, we produce almost all possible plain bearing dimensions.

PTFE composite bushings are referred to as prelubricated because their material is designed to operate with marginal lubrication.

VSB-11 Metal-Polymer Bronze Backed PTFE Plain Bearing
 

Structure Characteristics

 
Bronze Gleitlager Viiplus Bearing Metal-polymer self-lubricating composite materials consist of metal backing sintered porous bronze with PTFE polymer as working layer. The metal backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bonding between the backing and the bearing lining, the PTFE polymer offers exceptional low friction even under dry condition and the thermoplastic polymer is generally designed to operate with marginal lubrication. The construction promotes dimensional stability and improves the thermal conductivity. This material meets the demanding criteria for long life and trouble-free performance with or without lubrication.

· VSB-11
· Very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Suitable for lubricated applications
· Suitable for linear, oscillating and rotating movements
· Bronze back offers improved corrosion resistance in humid/saline environments
· Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surface, suitable for rotary and oscillating movement. Very high chemical resistance, low absorption of water and swelling, also performs very good lubrication feature, the bronze backing provides the improved corrosion resistance comparing with VSB-10.
Sliding Bearing Design, Selection, Inspection

Correct Design, Resonable Selection, Better Using

1. PTFE/fibre mixture thickness 0.01~0.03mm, 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 PTFE/Fibre mixture.
3. Bronze backing, provides exceptionally high load carrying capacity, excellent heat dissipation and very good corrosion resistance.
