- Shaft tolerance f7 to h8
SHAFT MATERIAL
- Steel, hardened or untempered, surface roughness ≤ Rz 2-3
MOUNTING ADVISE
- Housing: Mounting bevel min. 1.5 mm x 15-45°
- Shaft: Mounting bevel 5 mm x 15°, edges rounded
- The application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.
- Stick-in: Adhesive should not contact the sliding surface
MAINTENANCE
- TEF-MET®/B is a dry sliding bearing with a PTFE sliding layer. Lubrication is therefore not necessary, but basically possible!*
RANGE OF APPLICATION
- Machine and plant construction, textile processing and agricultural maschines, automotive industry
CAPTION
Special dimensions are only available on request
*If you like to use lubrication nonetheless, please remember to lubricate the sliding bearing regularly.
