Dental Chair and Stool Casters – Wholesale Supply for Dental Offices

Most dental chairs and operator stools use casters ranging from 2 to 3 inches in diameter. Dental stools typically use twin-wheel or ball-style casters with grip-ring or threaded stems. Selecting the correct diameter ensures smooth rolling, proper seat height, and compatibility with the chair's existing socket or stem configuration.

Common locking options include total lock (locks both wheel rotation and swivel), brake-only (locks wheel rotation), and non-locking swivel casters. For dental chairs where patient safety and stability are a priority, total-lock casters are strongly recommended. Non-locking swivel casters are popular for operator stools requiring frequent repositioning.
