Finishing Mandrel

Customer: Aerospace Manufacturing

Application: Large finishing mandrel used in sanding section 41 (Cockpit, Galley, and Crew Quarters) of the Boeing 787 aircraft

Issue: Load was extremely fragile and heavy at 35,000 per caster. The floor had minor variations in surface height. Space limitations would not allow for caster shift while swiveling.

Solution: Caster Concepts worked with the Boeing Offload Tool Design Engineering house to develop a double swivel caster to eliminate the castering effect of the tool as the casters went to swivel.
A super high capacity precision slew bearing was used for the main swivel while the 35,000 capacity 99 series swivel section was used as the secondary swivel bearing. An Oscillating axle was incorporated into the design to allow for inconsistent floor surfaces.
