Teflon Bronze Specifications

Teflon Bronze Bearings are among the highest performing plain bearings available. The porous bronze inner structure of Teflon Bronze Bearings acts as a reservoir for very low friction Teflon lubricant. The lubricant transfers, forming a film on the mating surface. As the film is depleted, the relative motion draws further lubricant from the bronze layer. When load or speed are significant, localized heat is generated and additional lubricant is forced to the surface. The bronze inner structure is bonded to a steel backing, giving Teflon Bronze Bearings a high load carrying capability and dimensional rigidity in addition to being able to withstand shockload.

Teflon Bronze Bearing Features:

• Medium Speed and Heavy Load capability
• Suitable for Rotational, Oscillatory or Linear Motion
• Resilient to Dirt, Dust and Shock Load
• Very High and/or Very Low Operating Temperature tolerant
