Brake Calipers Twiflex, with headquarters in Twickenham, England, specialises in the design, manufacture and supply of Advanced Braking Technology for industrial applications. With extensive in-house facilities, Twiflex enjoys a global reputation for quality. Founded in 1946, Twiflex has produced more than half a million brake units, frequently for safety-critical duty, for applications around the world. From textile machines in the north of England to the world’s deepest mine shaft in South Africa, Twiflex brakes are specified by engineers and system designers in every type of industry. From...

Select the right Twiflex Brake to meet your requirements The charts below illustrate the range of standard TWIFLEX disc brakes. Model-specific publications and data sheets are available for each caliper shown. To determine which will suit your application compare the braking force required with that generated by the calipers*, noting that other factors (e.g. disc speed, pad material, service factor, etc) should be considered for optimal selection. Twiflex application engineers can provide assistance for your particular application. Spring Applied Calipers† MUS - (P) MS - (P, H) MR - (P, H, E)...

Metals Twiflex brakes are used on critical applications throughout the metals processing industry for reliable dynamic, holding and emergency-stop duties. Typical applications include: • Rolling and slitting • Finishing and coating • Cranes and haulage • Shears and forging Mining For more than 40 years, Twiflex has been specified to provide safety-critical braking control in the mining industry. Typical applications include: • Winders and hoists • Conveyors • Grinding mills • Drag lines and shovels • Reclaimers and haulage Lifts and Escalators Disc brake systems are typically used on industrial (freight)...

Energy Disc brake systems are used on and off-shore in the wind, wave, tidal, and oil and gas industries. Typical applications include: • ind and tidal turbine W over-speed control • raw-works stopping D and holding • ind turbine yaw W motion control Entertainment Twiflex calipers are used to provide speed control, static holding, and emergency braking on a variety of applications, including: • • • • Theme park rides Simulators Stage gear, props and scenery Monorails Marine and Shipping Twiflex provides specialist solutions for the marine industry ranging from main propulsion shaft and thrusters...

Brake and System Overview ­ Couplings Twiflex manufactures a range of torsionally flexible, rubberelement couplings for a range of duties. Sometimes combined with a brake disc, they are a critical interface between components of a transmission system. Twiflex engineers are available to discuss, analyse and advise on coupling suitability for any application, and provide the technical support needed. Brake Calipers 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...

Brake and System Overview Hydraulic Power Units Monitoring Equipment A number of electro-hydraulic power pack options are available, from standard ‘on/off’ control units to fully customised closedloop braking systems. All require careful selection in order to ensure full compatibility with the type and number of brakes being controlled. Consultation with Twiflex engineers is recommended. • he LC range provides a basic ‘on/off’ control for a range of T Twiflex spring-applied and direct acting hydraulic calipers • he MP range of modular power units offers flexibility of design T and function •...

MU Series MU Disc Brake Caliper Range 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 caliper is suitable for use with a disc thickness of 8mm (.032 in), however, with a revised thruster mounting arrangement, may be used with discs 12.7mm (0.5 in) thick. Minimum disc diameter is 150mm (5.9 in). A range of brake discs is available from Twiflex (see Disc and Hub Assemblies). Fixing bolt to be supplied by the customer. For pneumatic operation use...

MS Disc Brake Caliper Range 154 (6.06 in) The Twiflex MS series of disc brake calipers is suitable for use with a disc thickness of 12.7mm (0.5 in). Minimum disc diameter is 250mm (10 in). Normally one or two calipers are used per disc, mounted horizontally (i.e. at the 3 o’clock or 9 o’clock position) to prevent rubbing of one brake pad due to self-weight of the thruster. A range of brake discs is available from Twiflex (see Disc and Hub Assemblies). (lb-ft) For pneumatic operation use dry, filtered and non-lubricated compressed air. Pneumatic brakes require a control valve, TWIFLEX operated...
