1. Low center of gravity The 50 mm widened nylon wheel increases ground . It has high elasticity and toughness, strong impact resistance, can absorb shocks and vibrations, and is very slipresistant and makes no noise when driving. 2. Flat mounting Coldrolled industrialgrade steel material, manufactured using a multilayer oxidation process, uniform thickness, stronger loadbearing capacity, used for heavy furniture wheels. When the brake is applied, the mounting plate and wheels are simultaneously locked. 3. 360° rotation without dead angle Double shaft plate precision ball bearing, smooth rotation, laborsaving, low friction, up and down double bead guide design, smooth rotation, more flexible steering, stable operation, suitable for transport. 4. Save worry and effort The wheel uses carbon steel balls inside, is 360° rotatable, flexible and smooth, easy to operate, and has high strength and hardness. With it, objects can be moved easily and ly to the desired location.
