The 2.5"/3"/4" Grip ring stem Twins wheels Medical Casters are specialized mobility solutions built for high-end medical equipment—think nursing trolleys, medication carts, diagnostic machines, and home care furniture. Compliant with the European EN 12530 standard (for medical equipment casters), they prioritize three core needs: ultra-quiet operation (critical for patient rooms), hygiene (anti-tangling design), and durability (resists frequent cleaning). Unlike general-purpose casters, they’re engineered to perform in sterile, calm healthcare environments.
Bracket: High-strength engineering PA (Polyamide) material—PA is lightweight, impact-resistant, and won’t rust, making it ideal for frequent disinfection. The integrated non-standard precision bearing turntable ensures smooth, effortless steering.
Wheels: PP (Polypropylene) core + TPR (Thermoplastic Rubber) surface—PP provides structural rigidity, while TPR delivers ultra-quiet rolling, floor protection, and shock absorption (critical for fragile medical supplies).
Bearings: Precision double ball bearings—reduce friction, ensuring the casters roll smoothly even after 10,000+ uses.
Fully enclosed anti-tangling design: Prevents hair, threads, or debris from wrapping around the wheels—eliminating a common hygiene risk in hospitals and making cleaning easier.
Clear brake/release functions: The brake system uses color-coded markers (e.g., red for brake, green for release) to avoid operator confusion—essential for fast-paced clinical settings.
Corrosion-resistant coating: All metal components (where used) are coated to resist moisture and disinfectants, ensuring the casters don’t degrade from daily cleaning.
Mounting options: Grip ring stem (tool-free, quick install), plate mounting (stable for heavy equipment), or thread stem (adjustable height)—compatible with 90% of medical trolleys.
Wheel sizes: 2.5” (75mm), 3” (standard), 4” (100mm)—2.5” for compact equipment (e.g., small medication carts), 4” for larger trolleys (e.g., nursing stations).
Load capacity: 70kg (2.5” model ME04-01-75TPRG) to 90kg (4” model ME04-01-100TPRG)—matches the weight of standard medical equipment.
Ultra-quiet performance: TPR wheels and precision bearings produce <40 decibels (similar to a quiet conversation)—no disruptions in patient rooms or operating theaters.
EN 12530 compliance: Meets strict European safety standards for medical casters, ensuring reliability in critical healthcare settings (e.g., ICU equipment).
Ergonomic efficiency: Lightweight (each caster weighs <300g) and smooth-rolling, reducing the force needed to move equipment—critical for nurses working 12-hour shifts.
Color customization: Available in white, gray, or black to match hospital decor or equipment branding.
A1: Yes. The fully enclosed design prevents debris accumulation, and the materials resist medical-grade disinfectants (e.g., alcohol or hydrogen peroxide). They meet the hygiene standards required for sterile operating room environments.
A2: Absolutely—use the grip ring stem option. Just push the stem into the trolley’s leg hole (matching size) until it clicks. No tools are needed, and the installation takes 2–3 minutes per caster.
A3: The precision bearings last 2–3 years with daily use. Yes, they’re replaceable—contact the manufacturer for replacement parts, and follow the included guide for easy installation.
A4: No. The TPR wheel surface is non-marking, so it won’t scuff polished linoleum or tile floors—maintaining a clean, professional look in hospitals or clinics.
