TASS brake test element TR4, 63 to 140 Nm - Bosch Rexroth 3609438143

A nutrunner working at up to 140 Nm should be checked against a reference regularly, without being removed from the machine. The TASS TR4 63-140 Nm brake test element is applied to the installed tool and checks torque, angle and linearity in one run. 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

• Testing in the installed state, the spindle stays in the machine and the cycle is barely interrupted
• Three parameters in one pass: two torque values, angle and linearity, no second test setup required
• Immediate feedback after the test run, so release or readjustment can be decided on the spot
• Characteristic values M1 63 Nm and M2 140 Nm cover the working range stated in the designation, M3 is specified as 175 Nm
• Size TR4 at 2.82 kg with a 38 mm width across flats, easy to handle at the station
