DB2017 Disc Brake Caliper - Type T40 Hydraulically Applied - 1

DB2017 Disc Brake Caliper - Type T40 Hydraulically Applied Nominal dimensions given. For specific dimensions please contact Twiflex Limited. Centre Mounting Plate 105 Space Required For Pad Removal Minimum Disc Diameter 300mm for full Pad Coverage 71 M24 Bolts Grade 8-8 Tightening Torque 680Nm (500 lbf-ft) Brake Disc Braking Force. 45kN @ 100 bar oil pressure (normal maximum working pressure). Braking Force is defined as the Tangential Force acting on the brake disc at the Effective Disc Radius. Braking Torque (Nm) = Braking Force (N) x Effective Disc Radius (m) Where Effective Disc Radius = Actual Disc Radius - 0.045. 80 60 40 Maximum working pressure 100 bar These figures are based on a friction coefficient (µ) of 0.4. These are typical performance figures for fully bedded and conditioned brake pads. For bedding-in and conditioning see publication M1060. When used with standard Twiflex brake discs an appropriate service factor should be applied when designing the braking system, and in case of brakes used for holding duties or in wet conditions this should be not less than 2.0.
