SKF FBF excavator bearing SX011818 Crossed Roller Bearing

Cross roller bearing is a split inner ring, outer ring rotation of special types of bearings. Because the divided inner or outer ring, after loading rollers and the spacing, a Cross-Roller Ring and secured together to prevent separation from each other, so the installation Cross-Roller Ring is simple. since the rollers is staggered, so only one set of Cross-Roller Ring can receive loads in all directions, as compared with conventional models, rigidity increased by 3 to 4 times. At the same time, because of the cross roller bearing inner or outer ring is constructed of two divided bearing gap can be adjusted, even if they are applied preload can be obtained with high accuracy rotary motion. Moreover, because of its special structure, commonly used in industrial robots bearing joints.

Install cross roller bearings, follow these steps:

1, check the installation of the front part: the spindle bearing or other mounting components thoroughly cleaned to remove oil or impurities, and confirm whether or burr burr.

2, the cross roller bearing into the shaft or bearing Lane: Because it is thin-walled bearings, load easily tilting. To prevent this behavior, while maintaining the level of the side with a plastic hammer beating evenly, little by little, the cross roller bearing or carefully loaded into the bearing shaft until confirmed by a sound when the plane is fully up and close.

3, flange mounting:

(1) placed on the flange cross roller bearing. Shake flange several times to match the bolt hole location match.

(2) the fixing bolt penetration hole. When the bolt is rotated by hand, make sure that no deviation from the bolt hole caused by a bolt screwed difficult.

(3) as shown, the fixing bolt locking the lock to full lock is not completely divided into 3-4 stages, the order on the diagonal repeatedly tightened. When tightening the inner or outer ring divided body, the whole of the outer or inner ring is slightly rotated some amendments can deviate from the inner and outer rings and body.

Edit this paragraph folded cross roller bearing Installation Notes:

1, cross roller bearing is divided into two parts of the inner or outer ring, using special rivets, bolts or nuts when delivered. When the cross-roller bearings installed in the system, not dismantle it. In addition, if you install the cross roller bearing isolators block error, it will seriously affect the performance of the rotation system. Do not remove the bearings.

2, cross roller bearing concentricity divided inner or outer ring may be slightly bias. Therefore, before loading the bearing can be used to loosen the inner or outer ring fixing bolts, and then use a plastic hammer deviation correction after assembly. 

3, when installing or removing the cross roller bearings, do not apply force to the connecting rivets, bolts and rollers.

4, when the mounting flange, to consider the dimensional tolerances of the mounting member such that the inner and outer flange pressed from the side. At the same time can not be too pressing cause bearing deformation, affect the rotation flexibility and bearing life. 

Edit this paragraph folded cross roller bearing Caution: 

1, foreign body into the bearings may cause damage, so please prevent dust, cutting chips and other foreign matter from entering the bearing. If reinjected fat dust, saw foreign material adheres, please use a clean white kerosene after cleaning.

2, the bearing temperature exceeds 80 degrees, please contact contact us to resolve.

3, when you want to use in place of regular vibrations, clean room, vacuum, low or high temperature and other special circumstances, please contact us for advice solutions.

Crossed Roller Bearing special design: special structure if needed (such as the outer ring with mounting holes, no inner hole, etc.), non-standard sizes, special materials and greater accuracy and so on.
