BRS High Precision Crossed Roller Bearing INA SX series

SX series crossed roller bearings are designed for high precision applications, its dimension belongs to ISO 18. Unlike CRB/RB crossed roller bearing, 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, can be divided into normal clearance, small clearance and preload(VSP type). Besides, SX0118 crossed roller bearings’ dimension are same to some deep groove ball bearings, which makes the replacement very convenient if customer want to improve current bearings’ loading capacity, rotation accuracy and stability, so there is no need to change the design of the applications.

SX Series Crossed Roller Bearing Features

1. Sustain radial, axial and moment loads at the same time.

2. High rotation accuracy is ensured through adjusting the bearing clearance to preload.

3. Stable rotation

Applications

SX cross roller bearings are specially suitable for the 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.
