introduction

Roller type freewheel clutch ALMKMSD2

Feature

Type AL..KEED2 is a roller type freewheel, self-contained, sealed and bearing supported, using two 160.. series bearings. Unit is delivered oil lubricated.This combination is used as overrunning clutch as shown overleaf.

In this design, a standard AL freewheel is connected to a flexible coupling for in-line mounting.The KEE type is a high performance coupling used to damp torsional vibrations and to accept misalignement without excess bearing loads. D2 cover is used to close the unit. It is equipped with two screws for oil filling, drain and level. We recommend the unit is supplied assembled.

Please specify inner race direction of rotation seen from the D2 flange. Refer to manufacturer’s catalogue to check coupling selection
