Additional information

Assembly

Hardened steel hub with H7 reamed hole and keyway in compliance with DIN 6885/1 P9 tolerance, sheet 2 and tab for fitting on handwheel hub.

Features and applications

The PTFE-coated surfaces provide minimal friction between bearing surfaces even when lubrication is being neglected. An oil-hole is provided which in the completely assembled safety handwheel connects the wheel to the hub.

Material

Steel with PTFE-coated sliding surfaces.
