Hard rubber casters from Xiamen Yirong Hardware Co., Ltd. offer a balance of durability and grip, ideal for applications requiring more rigidity than soft rubber but more floor protection than metal. Crafted from hard rubber (70-85 Shore A), these casters combine wear resistance with moderate shock absorption, making them suitable for medium-duty carts, office furniture, or light industrial equipment. The rubber treads grip surfaces like concrete, tile, or linoleum to prevent slippage, while resisting abrasion to maintain performance over time. Supporting 100-800kg, they roll smoothly with minimal noise, enhancing comfort in offices, workshops, or retail spaces. Swivel models feature precision bearings for 360° maneuvering, while fixed models provide straight-line stability. These casters bridge the gap between soft rubber (floor-friendly) and hard materials (durability), offering versatile performance for diverse applications.
