GN000.5 Coupling Attachment with Needle Bearings, for Safety Handwheels
This coupling attachment GN 000.5 utilises needle bearings. The use of needle bearings and the hardened bearing surfaces make the clutch engagement extremely straightforward. This is also assisted by the finer teeth of the clutch and the increased length of the coupling attachment.
Its suitability for high shaft speeds, especially when these are maintained for long periods, is a further advantage of the needle bearing.
An oil-hole is provided which in the completely assembled safety handwheel connects with the wheel hub.
Steel - hardened
Bearing surfaces - ground
