The Twiflex GMR and GMR40 series disc brake calipers are suitable for use with 25.4 mm and 40 mm thick discs, respectively. Minimum diameter of the disc: 610 mm.
Normally one or two pliers are used for each disk, but the number may be greater, depending on the size of the disk. The brakes can be positioned at any angle on the circumference of the disc, but the ideal solution would be to mount them horizontally (ie at 9 and at 15). If the mounting angle of the clamp is greater than 10 ° compared to the horizontal line, or in applications on vertical axis, it is possible to use a kit for inclined mounting. A wide range of brake discs is available from Twiflex (see Discs and hubs).
For the operation of the pneumatic units it is necessary to use filtered, dry and non-lubricated compressed air. Pneumatic brakes require a manually operated control valve or an electric or pneumatic signal.
The performances of the graphs referred to the various configurations are intended, with well-run shoes and with a coefficient of friction equal to µ = 0.4. Twiflex disc brakes must be used with asbestos-free Twiflex brake pads.
Effective radius of the disk = Radius of the disk (m) - 0.06 m. |
