TEF-MET®/P

Wrapped composite sliding bearing steel / Special PTFE coated Maintenance-free dry sliding bearing | DIN 1494 / ISO 3547

Bearing properties

TEF-MET®/P is a versatile dry sliding bearing with PTFE sliding layer. Therefore, no lubrication is necessary. However, it is very well suited for lubricated applications (e.g. hydraulic oil lubrication).
