Bore must be specified at time of quotation request and also on the order.

Dimensions in millimeters unless otherwise stated.

G is the amount by which clamping screws need to be withdrawn to release tire
J is the wrench clearance to allow for tightening and loosening the bush on the shaft and the clamp ring 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 project beyond the flanges as shown. In this event allow sufficient space between shaft ends for end float and misalignment.
Mass and inertia figures are for single flange with mid range bore and include clamping ring, screws and washers and half tire.
Flanges are also available finish bored with keyway if required.
Bore must be specified at time of quotation request and also on the order.

FLEXIBLE TYRE CODE NUMBERS
Unless otherwise specified Fenaflex flexible tyres will be supplied in a natural rubber compound which is suitable for operation in temperatures -50° C to +50° C. A chloroprene compound is available which is Fire Resistant and Anti-Static (FRAS) and has greater resistance to heat and oil. This is suitable for operation in temperatures -15° C to +70° C. For temperatures outside these ranges - consult your local Authorised Distributor. The FRAS tyre variant is used with specifically modified metal flanges to create the ATEX approved variant
