Install these ball transfers in a threaded hole or use a nut to secure.

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.

The flange has mounting holes for fastening.

A thick rubber cushion underneath these ball transfers absorbs impact and reduces vibration.

Transfers recess into the mounting surface for a low profile.

With a ball recessed into the mounting surface, these ball transfers have a low profile. Their double-sealed ball keeps out dirt and debris, and side vents expel contaminants.

Drop-in design makes for easy installation.

The ball in these transfers is spring-loaded to absorb impact.
