FAQ
Q: How does preload class C1 affect linear motion performance?
A: The C1 light preload (150N/33.7lbf) optimizes friction coefficient while maintaining 0.02mm (0.0008″) backlash control – ideal for high-speed packaging machinery.
Q: Can R162211322 handle vertical orientation in semiconductor handlers?
A: Yes, its 4-way equal load design supports 10800N (2,428lbf) static capacity in Z-axis configurations. Use ML0 ≤76Nm (56lb-ft) for wafer transfer arms.
