KB020AR0 Thin Section Bearings

KB020AR0 is a single-row angular contact ball bearing with a ‌circular window cage‌, which is available in brass or non-metallic composite material options. It belongs to the KB series of inch-sized thin-section precision bearings, specifically designed for space-constrained applications, achieving an excellent balance between lightweight design and high rigidity.
This is an ‌open-type non-sealed bearing‌, which adapts to user-defined independent lubrication schemes and comes with no pre-packed grease. It is widely used in scenarios with strict requirements for space, weight and rigidity, such as industrial robot joints, precision automation equipment, medical rehabilitation devices, and insulating glass production lines, and is especially suitable for the medium-sized joints of humanoid robots.
