A double-sealed ball keeps out dirt and debris, and side vents expel contaminants. With a ball that’s stainless steel, these ball transfers resist corrosion. They also don’t need to be lubricated. They can be used at an angle, so you can use them to build support stands.

Weight capacity is given for the ball up orientation. Using these ball transfers in a ball down or angled orientation could reduce the weight capacity stated.

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. These ball transfers were originally developed for the electronics manufacturing industry, where aligning glass layers in monitors and screens must be done without introducing dust. Use them to create conveyors, transfer tables, and material staging areas in your clean room.
