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,...

Twiflex disc brakes are found on industrial applications worldwide. 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...

Energy Disc brake systems are used on and off-shore in the wind, wave, tidal, and oil and gas industries. Typical applications include: • Wind and tidal turbine over-speed control • Draw-works stopping and holding • Wind turbine yaw 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...

Brake 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 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 closed-loop 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. • The LC range provides a basic on/off control for a range of Twiflex spring-applied and direct acting hydraulic calipers • The MP range of modular power units offers flexibility of design 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, however, with a revised thruster mounting arrangement, may be used with discs 12.7mm thick. Minimum disc diameter is 150mm. 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 dry, filtered and...

MS Disc Brake Caliper Range The Twiflex MS séries of dise brake calipers is suitable for use with a dise thickness of 12.7mm. Minimum dise diameter is Normally one or two calipers are used per dise, 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 dises is available from Twiflex (see For pneumatic opération use dry, filtered and non-lubricated compressed air. Pneumatic brakes require a control valve, operated either manually or by pneumatic or electrical signal. The ratings shown on...
