Features 1.Aluminum Alloy Material: The 60mm omnidirectional wheel is made of aluminum alloy materials, with high friction, light movement, solid structure. The omnidirectional wheel operates smoothly without jumping and low noise. 2.Omnidirectional Motion and Rotation: 60mm omni directional wheel can move and rotate in all directions, and have rotation and lateral mobility. It is easy to control and track the direction, making steering faster than ordinary wheels. 3.Round and Cross Shaft: Equipped with round and cross shaft couplings. It makes the omni directional wheel more solid, the fixed direction is clear, the installation selection is simple and stable, and the load stability is excellent. 4.Driven Pulley: Each driven pulley is embedded with two rolling bearings, precise machining and control of the driven pulley shaft clearance in a small range, especially suitable for a variety of small robots. 5.Composed of 8 Rubber Rollers: Each 60mm omni directional wheel is composed of 8 rubber rollers with a load capacity of 10KG. It is powered independently and has better stability.
