The Faultless Medical 4" x 1-1/4" Swivel Caster is precision-engineered for the unique mobility demands of medical, laboratory, and pharmaceutical environments. Featuring a non-marking thermoplastic rubber (TPR) tread, this caster ensures smooth, quiet movement while protecting sensitive flooring surfaces commonly found in hospitals and clean rooms.
Constructed with a durable stainless steel frame, the caster resists corrosion and is ideal for sterile or moisture-prone settings. It can be safely sanitized for infection control and long-term use in environments such as surgical suites, patient care units, and pharmaceutical labs. The industry-standard 2-1/2" x 3-5/8" top plate allows for secure mounting to a wide variety of medical carts, stainless steel utility tables, and case carts.
Supporting up to 190 lbs per caster, this model offers exceptional performance in medium-duty applications without sacrificing maneuverability. The 360° swivel design allows for precise directional control in tight spaces, which is critical in clinical settings where space is limited and safety is paramount.
Whether outfitting hospital equipment, clean room trolleys, or mobile surgical tables, this caster delivers quiet operation, hygienic strength, and user comfort. It also integrates seamlessly into healthcare workflows thanks to its low maintenance needs and compatibility with standard carts.
Trusted by professionals across the medical and laboratory industries, Faultless provides reliable, high-quality casters that meet rigorous operational and hygiene requirements. The SS-04TPX-125-SW-TP01 model exemplifies this commitment—offering a blend of durability, ergonomic performance, and floor safety unmatched in its class.
This MedCaster SS-04TPX-125-SW-TP01 4" x 1-1/4" TPR Swivel Stainless Caster – 190 lb is rated to 190 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.
This caster runs a Gray Rubber wheel with a 1-1/4" tread width. Rubber absorbs shock and protects floors, and runs quietly, which suits noise-sensitive and light-to-medium duty use.
This caster uses a top-plate mount with a 2-1/2" x 3-5/8" plate and a 1-3/4" x 2-13/16" bolt pattern. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.
This is a Swivel caster. Swivel casters rotate 360 degrees for full maneuverability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -20°F to 180°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Gray Rubber wheel performs best on rough, uneven, or outdoor surfaces such as asphalt, gravel, and cracked concrete. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 5.4375". Account for it when checking equipment clearance, dock height, and ergonomic working height.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
