Twiflex Brakes

Twiflex offers the largest range of industrial disc brake calipers in the world. Spring applied units may be retracted pneumatically, hydraulically or electrically (depending on caliper design) while most direct acting brakes have some form of positive retraction device.

Kor-Pak Corporation: Twiflex Brakes Dealer

Twiflex Spring Applied Brakes

Twiflex MU Series BrakesTwiflex MU Series Brakes MR-A

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.

Twiflex MS Series BrakesTwiflex Brakes T20-picture

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

Twiflex MR Series Brakes

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.

Twiflex Direct Acting Brakes

T2 Series Brakes

Twiflex T2 Brake

Twiflex T2 Brake

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.

Twiflex T20 Series Brakes

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.

T40 Series

Twiflex T40 Series Brake

Twiflex T40 Series Brake

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..

VKHD Series

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.

VH Series

Twiflex VH Series Brake

Twiflex VH Series Brake

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.

VMH Series

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.

Twiflex VKSD-VR

Designed for the industrial and mining sector, the VKSD and VKSD-VR (large pad) calipers are spring applied, hydraulically released disc brakes which comprise two spring modules located on either side of a mounting plate. The plate can be made in any thickness to accommodate brake discs of 20mm thickness or over.

The minimum disc diameter is 1000mm and there is no maximum. For high duty and frequent stopping applications the large pad version (VKSD-VR) offers excellent thermal capacity. With the brake in the “parked off” position, disc spring load and hydraulic pressure are zero, allowing pads to be removed in safety. This feature also permits brake installation without the need for hydraulic pressure.

LC – Electro Hydraulic Power Units

The “LC” range of stand alone power units is designed to operate the Twiflex range MR, MX, GMX, GMR and VCS spring applied hydraulically released brakes, providing a basic brake on/off control. There are various options available including “soft braking”, a range of operating and motor voltages, and various add-on accessories including a terminal box.

The “soft braking” option is available as an additional manifold slice to facilitate a fast approach, soft braking system. This enables rapid closing of the pad/disc air gap followed by controlled application of braking force up to full torque. Refer to data sheet DS3001.

MP – Electro Hydraulic Power Units

The modular “MP” range of electro-hydraulic power packs has been designed to provide a completely flexible means of brake control in the most arduous operating environments.

The units are composed of one of three base modules, dictated by the size and number of calipers to be controlled, comprising motor, pump and reservoir.

The hydraulic circuit is then selected, based on the operation and control logic required by the application and may range from a simple ‘on/off’ function to full closed loop PLC control. Finally, auxiliary options are specified (for example, hand pump for manual caliper release; heater for low ambient temperatures; stainless steel components for marine environments, etc.).

The “MP” solution is especially useful when the application requires independent control of multiple brake circuits. Refer to data sheet DS3002 or contact Twiflex for more details.
