How to order

Steel

Serrations nitrided

Bearing surface
TEFLON-coated

KeywayDIN 6885/2

Die Teflon-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 with the wheel hub.
