Dimensions in millimeters unless otherwise specified.
* G is the amount by which clamping screws need to be withdrawn to release tyre.
J is the wrench clearance to allow for tightening/loosening the bush on the shaft and the clamping screws on sizes F40, F50 and F60. The use of a shortened
wrench will allow this dimension to be reduced.
* M is half the distance between flanges, Shaft ends, although normally located twice M apart, can protect beyond the flanges as shown. In this event allow sufficient space between for end float and misalignment.
Mass and interia figures are for single flange with mid range bore and included clamping ring, screws and washers and half tyre. For pilot bore ‘B’ flange code is listed.
Flanges are also available finish bored with keyway if required.
Bore must be specified on order.
#Note: On sizes F70, 80, 100 and 120 the ‘F’ direction bush is larger than that in the ‘H’ direction.
