SPBL bushings, bronze with PTFE plugs (SL4), under water use   SPBL bronze embedded sliding bearing is made of high strength casting bronze, with PTFE solid lubricant embedded in holes on working surface of bearings, then have fine machining on CNC. The bearing combines the advantages of copper alloy and non-metallic friction-reduction material, it has better corrosion resistance performance, so it suits for application in the field of water conservancy machinery.

Structures ①  Bronze backing ②  Solid lubricant plug (PTFE) ③  Solid lubricant film

Typical Applications

• Usable in water
• Serviceable without the need for lubrication. Demonstrates high performance under high-load and low-speed operations.
• Demonstrates superior wear resistance in applications where oil film is seldom produced such as reciprocating motions, oscillation,
   frequent starts and stops, etc.
• Superior chemical resistance and corrosion resistance.
• Standard products are available.
