Direct Acting Calipers

The Twiflex MU series of disc brake calipers is the smallest in the Twiflex range and is primarily intended for light stopping and holding duties. Its design permits left or right-handed assembly.

The Twiflex MS series of disc brake calipers is suitable for use with a disc thickness of 12.7mm. Minimum disc diameter is 250mm.

The Twiflex MR series of disc brake calipers is suitable for use with discs of 12.7mm or 25.4mm thick. Minimum disc diameter is 250mm. Minimum disc diameter for the MR2 is 460mm.

The Twiflex MX13, MX25, MX30 and MX40 series of disc brake calipers is suitable for use with discs of 12.7mm, 25.4mm, 30mm and 40 mm thick respectively. The SMX caliper is only suitable for use with discs 12.7mm think. Minimum disc diameter is 300mm.

The Twiflex GMX series of disc brake calipers is similar to the MX range but offers greater pad area. The GMX25, GMX30 and GMX40 are suitable for use with discs of 25.4mm, 30mm and 40mm thick respectively. The SGMX caliper is only suitable for use with discs 25.4mm think. Minimum disc diameter is 610mm.

The Twiflex GMR and GMR40 series of disc brake calipers is suitable for use with discs of 25.4mm, and 40 mm thick respectively. Minimum disc diameter is 610mm.

For pneumatic operation use dry, filtered and non-lubricated compressed air. Pneumatic brakes require a control valve, operated either manually or by pneumatic or electrical signal.

The Twiflex T2 disc brake caliper is split caliper design suitable for use with a minimum disc thickness of 5mm. The modules are mounted each side of a central mounting plate of the same thickness as the brake disc. Minimum disc diameter is 120mm. Alternatively, the brake may be side-mounted with a spacer equal to the disc thickness between the two halves.

Low and medium duty calipers with two bolt side mounting. Has inlet port and bleed screw in each cylinder. Pads are replaced without removing the caliper.

The Twiflex T40 disc brake caliper is split caliper design suitable for use with a minimum disc thickness of 20mm. The modules are
mounted each side of a central mounting plate of the same thickness as the brake disc. Minimum disc diameter is 300mm..

Similar to the VKSD in construction, but the brake force is provided by direct hydraulic pressure. An internal spring retracts the pad from the disc.

Manufactured to stringent world wide mining authorities specifications.

Heavy duty base mounting caliper with spring retraction of pads and manual adjustment for pad wear. Special tandam VH calipers with double torque capacity are available.

Similar to the VMS in construction, but the brake force is provided by direct hydraulic pressure. An internal spring retracts the pad from the disc.

Manufactured to stringent British Coal Specifications.
