Application 1 — Hospital beds and patient transport
SX Series · Centralized brake
Polished 304 Stainless with Dual-Pedal Centralized Brake
Hospital beds need centralized braking — one pedal locks all four casters and the swivel simultaneously. Press the opposite pedal and all four release together. The SX series gives you that with polished 304 stainless construction, dual ball heat-treated swivel raceways for added cornering strength, and stainless precision ball bearings in the wheels for easier rolling motion when the patient is being transported.

Application 2 — MRI suites and non-magnetic environments
NM Series · Non-magnetic
Reduced-Metal + 316 Stainless for MRI Compatibility
MRI machines generate strong static magnetic fields. Standard metal casters get pulled toward the magnet, creating a safety hazard for patients and a calibration problem for the imaging equipment. The NM (Non-Magnetic) series uses glass-filled nylon for the body and rigging, with 316 stainless steel only where structural requirements demand it. Net effect: the caster doesn’t register on the MRI field gradient.

Application 3 — Surgical suite carts and instrument transport
SS Series · Polished stainless
Polished Stainless Swivel Casters with Easy-Roll Bearings
Operating room instrument carts, anesthesia carts, and crash carts all share the same caster requirements: stainless steel construction that survives daily caustic cleaning, sealed bearings that don’t shed particles into the surgical field, and quiet rolling so that caster noise doesn’t intrude during procedures. The SS series uses 304 stainless throughout with stainless precision bearings insert-molded into sealed raceways.

Application 4 — General clinical and rehabilitation equipment
NS Series · Next Generation
Next Generation Stainless Steel Performance — Maintenance-Free
Glass-filled nylon body with 304 stainless components (axles, mounting hardware) for chemical and water resistance. Maintenance-free: no grease zerks, no scheduled service. Designed for the bulk of clinical equipment that doesn’t need the centralized brake of a hospital bed or the non-magnetic spec of an MRI suite — wheelchairs, treatment carts, exam tables, mobile diagnostic units.

Why Medcaster instead of a generic stainless caster
Generic stainless casters are stainless on the frame but typically still use carbon-steel kingpins, brass bearing components, or non-medical-grade brake mechanisms. Medcaster builds everything to medical-grade tolerance from the start: heat-treated swivel raceways, sealed-for-life bearings (no grease that could contaminate a patient area), brake mechanisms tested against the actual hospital bed platforms they’ll mount to. That’s what makes Medcaster the spec on hospital purchase orders versus a generic stainless caster that costs less but doesn’t pass biomed engineering review.
Medcaster FAQs
Are these compatible with Hill-Rom, Stryker, and Steris hospital beds?The SX series with centralized braking is engineered to match the major bed platforms. Confirm bed model and existing caster mount pattern before ordering — mounting bolt pattern is the variable.
What’s the difference between SS and NS?SS is full polished 304 stainless (frame + rigging + wheel hardware). NS is glass-filled nylon body with 304 stainless components where structural — lighter, lower cost, still chemical-resistant, but not the all-stainless appearance.
Will the wheels mark a polished hospital floor?No — the standard wheel material on Medcaster series is non-marking polyurethane or thermoplastic rubber. Specifically engineered against vinyl tile and polished concrete.
How are these for autoclave or steam sterilization?Stainless rigging tolerates autoclave temperatures. The polymer wheels typically do not — the wheel material softens or deforms in 250°F+ environments. For autoclave-rated equipment, ask about high-temp wheel options.
Brake reliability over multi-year use?Medcaster brake mechanisms are tested to 10,000+ engagement cycles. Most hospital deployments run 5-7 years before brake service is needed.
