(Type F10 - bushing with a flange)
(Type W10 - sliding washer)
Sliding bushings made of wrapped, tin-plated steel (less commonly copper-plated) with a sliding surface made of PTFE polymer (polytetrafluoroethylene called Teflon).
Other manufacturers/distributors markings: TUP1, PAP....P10, PCM, SBT, BS.....
These are bushings with very low working clearance, very high load capacity and durability, designed for maintenance-free operation (they should not be lubricated!).
Series available in accordance with ISO 3547 and DIN 1494.
