Ball components

AMFLEX-S.A.F.E. ball components incorporate a floating ball that aligns itself up to 6 degrees to the angle of the part being machined, while maintaining precision height setting. The ball adjusts itself to draft angles and non-flat surfaces by virtue of a precision spherical seat which allows ease of movement under high loads, such as 1,800 to 22,500 lbs. depending on ball size. An O-ring incorporated into the housing insures that oil, cooling fluid, and dirt do not contaminate the ball seating area.

Harness mount system

Wire-harness mounting system is for high-volume harness manufacturing operations found in transportation, appliance, consumer electronics, and office equipment industries. Components of the system replace metal and plastic clips taped to the harness after construction. The tie harness-mount components are integrated into the harness construction process using cable ties to secure the mount to the harness. Ties can be hand-installed using hand or pneumatic-operated cable-tie tooling.
