Stroke: 315 mm
Load: 250 N (radially, centered)
Speed: 0.22 m/ sec.
Duty cycle pause: 1 sec.
Lead screw: high helix thread, 10 x 25 mm
Nut: SWZ-W-3008 (length: 30 mm)
The tested linear unit exceeds the required service life by more than a factor of 2
In the experiment number 428 of the igus® test laboratory, the wear behaviour of the special lead screw lift table was checked in a service life test. The special lead screw table was set up and tested in continuous operation under the following test parameters:
Test parameters:
Test setup: horizontal installation orientation
Test results:
Cycle count attained until discontinuation: 544,000 cycles
Axial clearance after test: approximately 0.6 mm
Torque after test: 0.8 Nm
At the time the test was discontinued, the linear unit was still operational.
Cumulative test power consumption: 1. Current (A) | 2. Cycle count
Conclusion:
The tested linear unit exceeds the required service life by more than a factor of 2. The unit attained 544,000 cycles instead of the required 200,000 cycles, at which point the test was discontinued.
