Products / Industrial Caliper Brakes / VKHD Series

The Twiflex VKHD disc caliper for industrial caliper brakes is comprised of two halves, or hydraulic modules, and is suitable for use with a minimum disc thickness of 20mm. The modules of the industrial caliper brakes are mounted on each side of a central mounting plate 12mm thicker than the brake disc. Minimum disc diameter is 1000mm.

In standard industrial caliper brakes, one or two calipers are used per disc, but the number may be increased depending on disc size. The industrial caliper brakes may be positioned at any angle around the periphery of the disc, but should ideally be mounted horizontally (i.e. at the 3 o’clock or 9 o’clock position). A range of brake discs is available from Twiflex (see Disc and Hub Assemblies).


The ratings shown on the graph are based on industrial caliper brakes with fully bedded in and conditioned brake pads with a nominal friction coefficient μ = 0.4. Twiflex disc brakes must be used with Twiflex asbestos free brake pads.


Effective disc radius = actual radius (m) – 0.095m.
