The REGL F5-D2 (or D3) series comprises an REGL Base Unit freewheel, combined with an F5 Torque Arm and a D2 (or D3) Cover Flange.
Torque is transmitted to the inner race via a key from the shaft and the outer race by means of a Torque Arm. Shaft tolerance must be h6/j6.
The primary use of the REGL F5-D2 (or D3) freewheels is as a backstop. The freewheel should be fixed to the machine body by use of a fixing pin attached to the F5 Torque Arm, and a suitable hole in the machine. Note that the radial clearance of 1% of pin diameter is needed between the pin and hole.
The unit is supplied with two paper gaskets for use between outer race and sealing cover/fixing plates. Failure to use the gaskets may cause loss of lubricant and subsequent rapid failure of the freewheel.
Prior to use, the freewheel must be lubricated as per instructions on page 35 of our current catalogue.
The REGL F2-D2 (or D3) unit is a self sealed design. If a D3 type End cap is used, a sealant must be applied to the keyway to avoid loss of oil lubricant through the keyway.
For pre-greased lubrication options the REGLG range is available, contact Renold Sales for assistance.
