AL12 ALP12 Roller 0.5KG Freewheel Cam Clutch Bearing
Features
Types AL, ALP are roller type freewheels. These units are
part of the modular system. They are bearing supported, using two
160.. series bearings, and require oil lubrication. These units may
be used in designs providing oil lubrication and sealing as on the
example overleaf.
The bearings must not be axially stressed. Typically, types
AL, ALP are used with standard covers that are designed to transmit
torque, and provide oil lubrication and sealing. Usually these
covers are used in pairs according to combinations shown on the
following pages.
The outer race of the AL model is plain to receive and
center any component bored to H7 tolerance. Torque is transmitted
by bolts through the cover plate in this case.
Types AL, ALP are identical except that type ALP has a keyway on
the outside diameter to transmit the torque.
Two paper seals are delivered with each unit to be placed
between the outer race and cover plates.
