In test number 428 of the igus® test lab, the wear quality of the special lead screw linear system was tested in a service life test. The special lead screw linear system was set up and tested in continuous operation with the following test parameters:
Load: 250N (radial, centrical)
Pause time: 1 sec.
Lead screw: high helix thread, 10 x 25mm
Nut: SWZ-W-3008 (length 30mm)
Test setup: horizontal installation position
Achieved cycle number until stop: 544,000 cycles
Axial clearance after test: approx. 0.6mm
Torque after test: 0.8Nm
Power consumption for duration of test: 1. Electricity (A) | 2. Number of cycles
Linear unit surpasses required service life by more than Factor 2. Instead of the demanded 200,000 cycles, 544,000 cycles were achieved and the test was stopped.
