SX thin-type precision bearings feature an ultra-thin design, with a smaller cross-sectional dimension compared to RB type bearings while maintaining the same journal diameter. Due to this ultra-thin design, neither the inner nor outer rings have mounting holes, requiring flanges and support seats for installation. They are typically used in applications requiring inner ring rotation.
Product Advantages
SX series cross roller bearings are a special type of bearing with a split inner ring and a rotating outer ring. The rollers are arranged in a cross pattern, allowing them to withstand loads in all directions. Compared to traditional models, their rigidity is increased by 3-4 times. The inner or outer ring is a two-part structure, and the bearing clearance is adjustable. Even under preload, high-precision rotational motion can be achieved. They feature high precision, high rigidity, high load capacity, and small size. They are commonly used as spherical plain bearings in industrial robots, offering 3-4 times higher rigidity than traditional models.
