Ball transfers solve a variety of material handling and motion control challenges, whether used in the traditional “ball up” position or as a caster in the “ball down” orientation. Ball transfers offer advantages to traditional casters, such as lower profiles and omni-directional movement, often at a lower cost.
Arrangement of the ball transfer units depends on the weight of the load, surface of the application and under-surface of the conveyed load. Determine the number of units required to support the load based on the considerations stated above. Once the number of ball transfer units has been calculated, these units should be arranged symmetrically under the load. The minimum distance between ball transfers should be the length of the shortest dimension of the load divided by 2.5. This minimum spacing will support the conveyed article and prevent it from becoming unstable. Our technical staff is available to assist you with mounting, loading, and spacing recommendations for your particular application.
