Mini-scissor lift tables are electro-mechanically operated. It comes with two push buttons to control the vertical motion. It is usually available with casters for mobility.
Single-row deep groove radial ball bearings are the most common type of miniature ball bearings. It has a wide range of suitable applications. The raceway grooves on both inner and outer rings have circular arcs of slightly larger radius than that of the balls. In addition to radial loads, axial loads can be applied in either direction. Because of their low torque, they offer high-speed operation with low power loss.
