Caster 3″4″5″ Stainless Steel Anti-Rust Wheels Casters MOQ 100PCS

This heavy-duty load-bearing retractable caster adopts a foot-operated one-click lifting structure. A light step enables the caster to extend or retract, allowing easy switching between the “mobility” and “fixation” modes of the equipment. The bracket is made of thickened cold-rolled steel plate, and the wheel body is available in polyurethane, nylon or rubber materials. Each single wheel can bear a load of 100–500kg. Equipped with double ball bearings, it features flexible and smooth steering as well as quiet, anti-slip performance. Available in three types—fixed, swivel and brake-equipped—it supports multiple installation methods such as screw mounting and welding. Widely used in scenarios like industrial equipment, medical instruments and office furniture, it solves the pain points of fixed casters being hard to move and swivel casters tending to slide. It is a high-quality accessory that improves the flexibility of equipment use.
