Delrin® Acetal—Able to hold tight tolerances, these balls resist expanding when exposed to heat and moisture. They have a naturally slippery, wear-resistant surface. Use them for bearings and low-load rolling applications. Delrin® acetal resin is also known as acetal homopolymer.

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. 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.

Acetal Ball—Acetal ball transfers are best for light duty applications.
