Checklist
Mounting Fasteners
г
Inspect fasteners for proper torque, interferences, and wear. Tighten and correct as required. Refer
to
Ball Bearings/Alignment Pins/Bushings/Bearing Race
г
Inspect for wear and proper lubrication. MobilGrease XHP222 Special a NLGI #2 lithium complex
grease with molybdenum disulfide additive is suggested for locking mechanism and alignment
pin lubrication. Over time, lubricants can become contaminated with debris. Therefore, it is
recommended to thoroughly clean the existing grease and replace with new as needed. See
Section 5.2—Cleaning and Lubrication of the Locking Mechanism and Alignment Pins
.
г
Inspect for excessive alignment pin/bushing wear that may be an indication of poor robot position
during pickup/drop-off. Adjust robot position as needed. Check tool stand for wear and alignment
problems. The QC-27M model has replaceable alignment pins, refer to
г
Wear on the balls/bearing race could be an indication of excessive loading.
Sensors and Cables
г
Inspect sensor cable connectors for tightness, and if loose, tighten the connections.
г
Inspect sensor cables for any damage, cuts, and abrasion. Replace as necessary. Refer to
