💡 What steps prevent premature wear when replacing linear bushings on a moving gantry?

- Check the outer casing clearance fits your mounting brackets tightly
- Wipe the contact track clean before seating the recirculating steel spheres
- Pack each unit sparingly with grease so friction stays low on the rails
