Harsh Environment Dry-Running Sleeve Bearings
Even in the presence of harsh chemicals and extreme temperatures, these bearings operate under heavy loads and at high speeds.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

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.
Vespel® polyimide ball transfers are nonconductive, which means they prevent stray electrical charges from passing between your material and equipment. They're best for moving glass and other material with a polished surface because they're smoother than acetal and PEEK ball transfers and won't scratch surfaces.
