n the railway industry, plain bearings and self-lubricating bushings play a crucial role in ensuring smooth and reliable operation of various mechanical components. Among these, PTFE (Polytetrafluoroethylene) sleeve bushings are particularly suitable for heavy-duty linear plain bearing applications due to their exceptional properties.

PTFE sleeve bushings are made from a high-performance fluoropolymer material that offers excellent wear resistance, low friction, and chemical stability. These bushings are designed to withstand high loads and temperatures, making them ideal for use in demanding railway environments.

In heavy-duty linear plain bearing applications, PTFE sleeve bushings provide a smooth and consistent sliding surface that reduces friction and wear. The self-lubricating properties of PTFE allow these bushings to operate with minimal lubrication requirements, further enhancing their reliability and reducing maintenance costs.

The use of PTFE sleeve bushings in railway applications such as bogies, axles, and other critical components helps to ensure smooth and quiet operation while reducing the risk of wear and tear. This extends the service life of the equipment and reduces the need for frequent repairs or replacements.

Overall, PTFE sleeve bushings are an excellent choice for heavy-duty linear plain bearing applications in the railway industry. Their exceptional properties, including high wear resistance, low friction, and self-lubricating capabilities, make them ideal for use in demanding environments where reliability and durability are paramount.

Bronze + Bronze Powder + PTFE/Fibre

Dry Maintenance Free Bronze Base  Self Lubricating Bush SF-1B

· 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.

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.
