RDBK
Type RDBK is based on the RSCI centrifugal lift-off freewheel but is also equipped with a frictional torque limiter.
RIZ and RINZ
Types RIZ and RINZ are centrifugal lift-off sprag type freewheels with an inner race that moves during rotation.
RIZ..ELG2
The RIZ..ELG2 is a special kind of centrifugal lift-off sprag type freewheel with an inner race that moves during rotation.
RIZ..ESG2
The RIZ..ESG2 is a centrifugal lift-off sprag type freewheel with an inner race that moves during rotation.
RSCI
The RSCI is a centrifugal lift-off sprag type freewheel with an inner race that moves during rotation. Only this inner race is suitable for the overrunning motion, and the freewheel itself has no bearings.
RSRV and RSRT
The RSRV and RSRT are a special type of centrifugal lift-off freewheel. They are based on the RSCI sprag type freewheels but are also equipped with a frictional torque limiter.
RSXM
The RSXM series complements the RSCI range by offering freewheels in compact sizes. This special RSXM version is a sprag type freewheel that is characterised by the way the sprags lift off centrifugally when the inner race rotates.
