Chesterton ® Hydraulic/Pneumatic Division 16K Metric Bearing Band Strips 16K - Product Data The 16K Metric Bearing Band Strips are the solution to costly cylinder re-machining and repairs for large diameter equipment. The bearing material is made from a thermoset polyester resin reinforced with synthetic fabric specifically designed to support heavy loads. The exceptional physical properties and built-in PTFE lubricants make it suitable for use on rams or pistons in reciprocating applications. Features & Benefits: ■ Prevent metal to metal scoring and prolong equipment life. ■ Reduce radial movement on both rams and pistons therefore extending seal life. ■ Built-in lubricant allows for lower coefficient of friction between mating surfaces. ■ Retrofit existing bearing grooves and eliminate unnecessary modifications. ■ Available in common sizes which minimizes inventory costs. ■ Cut to size from coil and accommodate equipment over 300 mm in diameter.
