Light- Medium Duty NSF-Listed Sanitary Friction-Ring Stem Caster; 325 lb. Load Rating, 5" Wheel Dia.

NSF-listed sanitary friction-ring stem casters are built to satisfy the National Sanitation Foundation's (NSF) rigorous testing requirements for casters that are used in environments where they will be exposed to frequent washdowns, oils, or chemicals. They are used in food-service areas, food-manufacturing facilities, cleanrooms, and similar environments where sanitary conditions must be maintained. The casters have double ball swivel bearings that allow them to swivel smoothly.

Friction-ring stem casters each have a stem that presses into an appropriately sized hole or socket in tubes, pipes, wood, or compatible brackets on furniture or equipment. A spring ring at the end of the stem expands to hold the caster in place once it's installed in the hole or socket. Also known as grip-ring stem casters, these casters are used on furniture or equipment such as office chairs, tables, and medical equipment to allow them to roll as they're being moved or repositioned. Friction-ring stem casters require few or no tools for installation, making them well suited for applications where casters need to be replaced frequently. These swivel casters can rotate 360°, allowing equipment to change directions while rolling.
