The casters' wheels are impregnated with an antimicrobial compound that prevents microbes from growing on the wheels and damaging them or causing odors. The casters have thread guards that stop dirt and debris from getting into the casters and damaging them. The casters' wheels have precision ball bearings that provide quiet rolling, and the casters have double ball swivel bearings for smooth swiveling. These casters are used on carts and equipment in locations where noise must be minimized and high standards of cleanliness must be maintained, such as medical, laboratory, pharmaceutical, and food-service facilities.

Maintenance-free high-performance expanding stem casters have sealed precision ball bearings in their swivel raceways and wheels that do not need to be routinely greased. This reduces time spent on maintenance and helps extend the life of the casters. These casters roll more quietly than other types of expanding stem casters. The casters' nylon frames resist chemicals and corrosion and weigh less than metal frames. This makes these casters well suited for use on carts, racks, and other equipment in medical facilities, pharmacies, laboratories, food-service areas, and other settings where the equipment will be moved frequently and may be exposed to chemicals. The casters have thread guards that prevent dirt and debris from getting into the casters and damaging them.
