- **Caution**: 

### Q: What is the difference between lead screw and ball screw in linear actuators?
**A**: Lead screws use sliding contact for cost-effective precision, while ball screws use rolling elements for higher efficiency and speed, making them ideal for demanding industrial applications.

### Q: How do I select the right linear actuator for my machinery application?
**A**: Consider load capacity, speed requirements, stroke length, duty cycle, and environmental conditions. Our actuators offer customizable specs including motor type, screw selection, and housing materials.

### Q: What maintenance do industrial linear actuators require?
**A**: Regular lubrication of screw mechanisms, inspection of limit switches, and cleaning of piston rods. Our aluminum/stainless steel construction minimizes corrosion for reduced maintenance in harsh environments.
