TASS brake test element TR4, 54 to 120 Nm - Bosch Rexroth 3609438142

Testing spindles between 54 and 120 Nm calls for a reference that works on the installed spindle. The TASS element TR4 54-120 Nm simulates the joint as a brake test element and records two torque values, the angle of rotation and linearity in a single pass. As the largest size of the TASS elements, TR4 has a 38 mm width across flats and a length l3 of 273 mm, and weighs 2.82 kg.

Benefits

• Three parameters in one pass: two torque values, angle and linearity, no second test setup required
• Testing in the installed state, the spindle stays in the machine and the cycle is barely interrupted
• Suitable for short intervals, for example daily, so deviations are detected before they carry over into many joints
• Characteristic values M1 54 Nm and M2 120 Nm cover the working range stated in the designation, M3 is specified as 150 Nm
• Size TR4 at 2.82 kg with a 38 mm width across flats, easy to handle at the station

Specifications

Applications

• Daily validation of tightening stations in the 54 to 120 Nm range
• Setting nutrunners after maintenance or modification of the spindle
• Checks of handheld and fixtured nutrunners with a target value in this torque band

System compatibility

• TASS (Tool Analysis and Setup System) by Bosch Rexroth, size TR4 with elements from 54 to 160 Nm
• Adapters match the interface to the joint (hex socket, external hex, Torx, internal thread)
