DH Casters Swivel Caster With 3 inch Polyolefin Wheel gives shop and facility carts a compact wheel that supports frequent moves under moderate loads. The 3 inch wheel diameter keeps overall cart height manageable while still rolling smoothly across typical shop and warehouse floors. A 1-1/4 inch tread width spreads the load across more surface area, which helps the wheel track straight under weight and turn cleanly when the swivel rotates. The heavy plastic polyolefin wheel material is specified as non-marking, so it rolls without leaving streaks on finished floors in medical, lab, food service, and institutional spaces. A built-in brake lets the caster hold position when carts are staged, which aids stability during loading or work at a fixed location. Combined with the swivel design, this caster supports both tight maneuvering and stable stops in daily cart use.
This plate mounted casters design centers around a 2-3/8 inch by 3-5/8 inch plate, so the caster fastens flat to a cart or equipment base built to accept that footprint. By using a plate mount rather than a stem, the load distributes over the plate area, which benefits shop carts and moving dollies that see frequent rolling under varying loads. The swivel type layout lets the wheel rotate freely around the vertical axis, giving pushers precise control as carts move through tight service corridors or between warehouse racks. Because the wheel diameter is 3 inches with a 1-1/4 inch tread width, installers can plan deck height and clearance under carts to match existing equipment runs while maintaining a stable stance.
This DH Casters swivel caster is defined for use on shop carts and equipment, where the 300 lb load capacity per caster helps support tool loads, parts bins, and general shop materials. The same construction is specified for medical and lab carts, so the non-marking polyolefin wheel can roll across clinical floors without leaving residue when carts are positioned repeatedly. Food service equipment also falls within the listed applications, where the zinc plating and non-marking wheel work together in kitchens and prep areas that are cleaned frequently. Warehouse carts and bread racks benefit from the 3 inch wheel diameter, which balances low overall height with easy rolling when workers move product along aisles. Automotive and electrical equipment carts use this caster to move heavier components, and moving dollies use the plate mount footprint to carry boxed goods through storage and staging spaces.
The full double ball bearing heat-treated raceways built into the swivel head provide smooth rotation under changing loads, which reduces binding when operators turn carts sharply in tight quarters. An axle and nut wheel assembly secures the 3 inch by 1-1/4 inch polyolefin wheel, helping the wheel stay aligned in the fork as the caster sees repeated directional changes on shop and warehouse floors. Zinc plating applied to the caster components offers corrosion resistance, which supports service in environments where moisture, spills, or frequent cleaning are present, such as food service equipment lines or medical and lab carts. The non-marking heavy plastic polyolefin wheel construction lets carts move through finished corridors, production areas, and institutional spaces without transferring wheel marks, reducing follow-up cleaning passes after material moves. Because the caster is a swivel type with an integrated brake, carts can be steered into tight positions and then held in place during loading, unloading, or on-site work.
This DH Casters swivel caster uses a 3 inch wheel diameter with a 1-1/4 inch tread width, which balances low cart height with stable contact and maneuverability for carts and equipment.
This plate mounted caster has a 300 lb load capacity, so cart designs can allocate weight per caster around this rating when planning total load for shop, warehouse, or institutional carts.
The caster uses a 2-3/8 inch by 3-5/8 inch plate size, which provides a flat mounting surface that spreads load into the cart base for stable operation under rolling loads.
The non marking polyolefin wheel suits medical and lab carts, food service equipment, and other institutional or industrial areas where floors need protection from wheel marks during frequent moves.
The swivel design lets the caster rotate around a vertical axis, allowing carts to change direction smoothly in tight aisles, around equipment, and in crowded work areas.
Zinc plating on the caster components provides corrosion resistance, supporting performance in environments with moisture, spills, or regular cleaning such as food service or medical areas.
This DH Casters 300 lb swivel caster with brake combines a 3 inch non-marking polyolefin wheel, zinc-plated construction, and a 2-3/8 inch by 3-5/8 inch plate mount to support controlled movement on shop carts, medical and lab carts, and food service or warehouse equipment. By aligning cart layouts, deck thickness, and load expectations with the 300 lb capacity and wheel dimensions, builders can put this plate mounted casters design to work wherever maneuverable, low-profile mobility is needed for daily operations.
