SX series crossed roller bearings are designed for high precision applications, its dimension belongs to ISO 18. Unlike CRB/RB crossed roller bearing, the SX slewing ring’s split outer ring is fixed by three locking rings instead of screws.
SX crossed roller bearings have higher rigidity and running accuracy. Its clearance can be divided into normal clearance, small clearance, and preload(VSP type). Besides, SX0118 crossed roller bearings’ dimensions are the same as some deep groove ball bearings, which makes the replacement very convenient if the customer wants to improve the current bearings’ loading capacity, rotation accuracy, and stability. There is no need to change the design of the applications.
1. Sustain radial, axial, and moment loads at the same time.
2. High rotation accuracy is ensured by adjusting the bearing clearance to preload.
3. Stable rotation
SX cross roller bearings are especially suitable for applications where space is limited, while high rigidity and high rotation accuracy are required. Such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments, and IC manufacturing machines.
