Material Handling

Stud-Mount Ball Transfers

Install in a threaded hole or use a nut to secure.

Washdown Stud-Mount Ball Transfers

Ball transfers have a double-sealed ball to keep out dirt and debris. Side vents expel contaminants.

Clean Room Stud-Mount Ball Transfers

Unlike most ball transfers, which have metal balls, these have a plastic outer ball that rolls on stainless steel inner balls, so there's no metal-on-metal contact that could create and release particles into your clean room. They've also been ultrasonically cleaned and then individually bagged to prevent dust contamination.

Heavy Duty Stud-Mount Ball Transfers

These ball transfers have capacities up to 2,200 lbs.

Ball Transfers for Delicate Surfaces

A large-diameter rubber ball handles delicate or polished surfaces. The stem spins and the ball rotates around the stem.

Drawbar Rings

These rings mount to a trailer and connect to the drawbar coupler or tow hook on a vehicle.

Tooling Balls

The shoulder on these tooling balls provides a consistent height reference point.
