Technical data

Types of Crossed Roller Bearings

CRBC Series: Consist of an inner ring and outer ring, which is suitable for rotating the inner ring and outer ring in both

Structure of sealed type and open type

1. Sealed type: The seal has a perfect sealing effect, which can effectively prevent the foreign substance from entering the track and the lubricant from leaking from the channel. In addition, the seal has oil holes for lubricating.

2. Open type: There is no seal. The friction resistance is more minor. It is suitable for the use of low torque. The Open type also has oil holes for lubricating

Installing steps

Upon installation of the Crossed Roller Bearing, please follow:

1. Inspect parts before installing: Clean bearing bracket, central axle, or other details to remove dirt or grease

2. Place the bearing into the bearing bracket and central axle: As for the design of clearance match, keep the bearing horizontally and insert the bearing into the bearing frame or axle. If it is challenging hard the installation, use a rubber hammer to slightly hit every part of the bearing so that the bearing can be inserted into the bracket or axle easily. Finally, the sound change confirms the match of bearing and bare face. As for the design of interference match, Use heating or cooling to expand or shrink the parts for ease of installation. But the bearing temperature should not be over 80℃C. In addition, it has to pay attention to the hitting force of the bearing; if the point is too large, the bearing may be damaged. If the inner ring or outer ring of the split bearing is acentric, the bolt of the inner ring or outer ring can be loosened slightly. Then, turn the outer ring or inner ring up or place the bearing into the bearing bracket so that the bearing can be established smoothly.

3. Install mounting disc: Place the mounting disc on the bearing, and align the screw hole for locking the bolt. Tighten the bolts diagonally. Then tighten all bolts in sections. Prevent tightening all bolts at a time.

Description of lubrication

1. There is the lubricant in all Crossed Roller Bearings. So, the delivered bearing can be used directly, If the lubrication is insufficient, the friction resistance will be increased, and the service life will be reduced. The lubricant should be supplemented for the open bearing periodically, The lubricating frequency depends on the use condition- Installation sequence. The lubricant should be distributed evenly inside the bearing.

2. Prevent mixing different lubricants

3. If the bearing is used at a high vibration, clean room, vacuum, high temperature, or low temperature, the specific lubricant should be used, please contact us.

Use cautions

1. The average use temperature of the bearing is 10-80℃; if it is over this temperature range, please contact us.

2. If a foreign substance enters the inside structure of the bearing, the rotation route of the roller may be damaged, and even the bearing may fail. So, prevent the foreign substance enters into the inside structure of the bearing.

3. If a foreign substance enters the inside structure of the bearing, please clean it and then refill the lubricant.

4. Please do not remove the bolt and nut of the split bearing. Upon installing, please do not apply force to the bolt and nut.

The application of the CRBC series crossed roller bearing.

CRBC series crossed roller bearing is a lightweight, compact type with the thinnest possible inner and outer rings, especially for the lightest, with high rigidity. It is optimal for applications such as joints, swiveling units of industrial robots, and swiveling tables of machining centers. Rotary units of manipulators. Precision rotary tables, medical equipment, measuring instruments, and IC manufacturing machines.
