Flexible Directional Casters, Shock Absorbing PU, Protects Floors Provides Smooth Movement

The wheels are made of PU and iron. The rotating upper plate adopts a single steel ball track design, which has large bearing capacity and flexible rotation. The lower pallet and angle are made of steel plate stamped and welded. The soft PU wheel has shock absorption and abrasion resistance, which can ensure that the wheel rolls smoothly without making a harsh sound or leaving scratches on the surface.
