The twin-wheel structure divides the equipment’s weight across two contact points, reducing pressure on floor surfaces and minimizing wheel wear. This design allows the caster to support heavier medical devices without compromising mobility.
The grip ring stem design enables fast assembly and disassembly without additional tools. The ring structure tightly grips the equipment’s mounting hole, preventing loosening even during frequent movement, which saves maintenance time for healthcare facilities.
With three size options (2.5"/3"/4"), this caster is compatible with almost all types of mobile medical equipment. Whether for lightweight nursing carts or heavy-duty diagnostic machines, it delivers consistent performance across diverse healthcare scenarios.
