Sprag freewheel cage GM series

backstopindexingoverrunning clutch

the GM series.... is a cage with contact elements running on a metric sized freewheel race. the smaller dimensions and the high transmission torque offer some interesting technical and cost-saving solutions. Fitting multiple cages side-by-side increases torques. It is necessary to place one or two bearings next to the freewheel so that the outer race can rotate centrally to the inner race. When the sliding race is machined in the seats or on the shafts, the following specifications must be adhered to: 1) 60/62 hrc surface hardness 2) 1 mm minimum depth of tempering after grinding 3) ensure the concentric rotation of the races 4) lubrication suitable for the application.
