It also provides soft rubber wheels that can be used for hardwood floors and popular polyurethane wheels that can be used for both hardwood floors and carpets. Soft rubber wheels are available in 2 "and 3" diameters.

Steering: Hard, narrow wheels are easier to steer than soft, wide wheels. The turning radius is an important parameter for the turning of the wheel. If the turning speed is too short, it will increase the difficulty of steering. If it is too large, it will cause the wheel to shake and shorten the life. Factors affecting the flexibility of casters are: the structure of the bracket and the choice of bracket steel, the size of the wheel, the type of wheel, the bearing, etc.
Although we do not recommend any casters for cork floors like pine, some soft rubber wheels have been successfully used for cork floors. The weight that industrial casters can withstand at rest. The static load should generally be 5 to 6 times the driving load (dynamic load), and the static load should be at least 2 times the impact load.
