The Twiflex VKSD disc brake caliper is comprised of two halves, or spring modules, and is suitable for use with a minimum disc thickness of 20mm. The modules are mounted each side of a central mounting plate 12mm thicker than the brake disc. Minimum disc diameter is 1000mm.
The Twiflex VS disc brake caliper is comprised of two modules secured between U-shaped top and bottom mounting plates by tie rods.
The Twiflex VMS3-SPS disc brake caliper is comprised of two modules bolted to a central mounting plate, 12mm thicker than the brake disc. Minimum disc thickness is 38mm and minimum disc diameter is 1500mm with no maximum except for practical limitations. Based on a development of the earlier Twiflex VMS2-SP disc brake, the VMS3-SPS provides a significant increase in braking force but in a similarly sized package.
Infinite fatigue life (>2 x 106 cycles) is achievable for most units at the 3mm air gap shown in the table and possible, by reducing this setting, for the higher rated brakes – contact Twiflex for further information.
Effective disc radius = actual radius (m) – 0.155m.
