Premium Medical-Grade Silent Swivel Caster with Total Lock – M12 Threaded Stem (4″/5″ Options)

Professional Grade Mobility Solution

Designed for medical carts, hospital beds, and high-end laboratory equipment, our TSD Series Casters provide the perfect balance between effortless movement and rock-solid stability. The dual-wheel design ensures a low center of gravity and smoother turns compared to single-wheel alternatives.
### Key Material & Performance Features:
Advanced PA6 & PP Core: The frame is constructed from high-load reinforced Nylon (PA6), providing exceptional structural integrity and impact resistance.
Premium TPU Tread: The outer wheel is made of wear-resistant Thermoplastic Polyurethane (TPU). It is specifically designed to be oil-resistant, water-resistant, and anti-corrosive, while significantly dampening noise.
Precision Ball Bearings: Equipped with high-precision internal bearings to reduce friction, ensuring the caster glides smoothly even under maximum load.
Total Lock System: The “Total Lock” brake is a critical safety feature—one press stops both the wheel rotation and the swivel direction entirely.

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.
