SX Series Crossed Roller Bearings

SX series crossed roller bearings are designed for high-precision applications. Unlike the CRB series crossed roller bearing, the SX series crossed roller bearing 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 average, small, and preload(VSP type). Besides, SX0118 series crossed roller bearings’ dimensions are the same as some deep groove ball bearings, making 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.

SX series crossed roller bearing characteristics:

1. Have average clearance or are preloaded

2. Fixed the adjacent construction using clamping rings

3. Suitable with average clearance for circumferential

4. Shaft diameters from 70 mm to 500 mm

Installation instructions for cross rollers bearings

The cross roller bearing should be mounted with the following steps:

1. Inspection before mounting the parts:

Wash and clean the bearing base or other mounting parts to remove the dirt and confirm that the burr on the details has been removed.

2. Mount the bearing into the bearing base or onto the shaft. Because the thin-walled bearing may be mounted tilt, it should be leveled and mounted by beating it evenly with a plastic hammer in the circumferential direction until it is fully contacted with the contact surface can be confirmed with the sound.

3. Side pressing flange mounting

(1) Place the side pressing flange in place, and shake it back and forth several times in the circumferential direction to adjust the positions of the mounting bolts.

(2) Mount the pressing bolts. Tighten the bolts manually and ensure no deviation from the bolt holes.

(3) The pressing bolts can be tightened progressively and diagonally in 3~4 stages. Slightly rotate the integrated inner or outer ring to correct the two divided parts.

Приложения

SX series crossed roller bearings are especially suitable for applications where space is limited. At the same time, 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.
