4″ 5″ Professional Medical Wheels-Grade Silent Swivel Casters – Plate Mounting

## Advanced Engineering for Healthcare
Our TSD series is specifically designed for high-end medical carts, diagnostic equipment, and hospital beds. Whether you are replacing old wheels or building new equipment, these casters offer industry-leading stability.
### Performance Features:
Reinforced Structure: The frame uses PA6 (High-strength Nylon) and a PP core for maximum impact resistance.
Superior Floor Protection: The high-quality TPU (Thermoplastic Polyurethane) tread is soft enough to protect delicate flooring but durable enough to resist oils, water, and detergents.
Total Lock Brake System: Provides rock-solid stability during surgical or diagnostic procedures.

FAQ
Q: What does “Total Lock” mean?
A: Unlike standard brakes that only stop the wheel from rolling, our Total Lock mechanism freezes both the wheel rotation and the swivel head. This ensures the equipment stays exactly where you put it without any “drifting.”
Q: Will these wheels leave marks on my floor?
A: No. The TPU (Thermoplastic Polyurethane) tread is non-marking and floor-friendly, making it safe for hardwood, tile, and specialized medical linoleum.
Q: Can I use these in cold storage or high-heat areas?
A: Yes, these casters are rated for extreme environments, performing reliably in temperatures ranging from -30°C to +80°C.
Q: Is the mounting bolt included?
A: The caster comes with an integrated M12x25mm threaded stem. Please ensure your equipment has a matching M12 socket for installation.
