Product Description

NRXT2508 N series crossed roller bearings for the rotating joints of robots

N series Crossed Roller Bearings are thin-wall bearings consisting of an inner ring, a two-part outer ring, cylindrical rollers, and separators. The rollers are oriented at right angles to each other and kept apart by separators.
 
This kind of N series Crossed Roller Bearings can sustain axial loads in both directions as well as radial loads and strong moment loads. And with their internal clearances factory-adjusted, it can be installed directly without troublesome shim adjustment. Mounting is facilitated by the outer ring parts being inseparable

Feature of Crossed Roller Bearing

 

1. High accuracy and load capacity. Precision ground V grooved ways and rollers. 

2. Withstands force in any direction. Alternately crossed rollers 45º angle.

3. Easy Installation and get used to small spaces. Threaded mounting holes in standard pattern.

4. Factory preloaded for minimum axial play and low coefficient of friction.

 

Installation & Cautions

 

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

2.Place the bearing into the bearing bracket and main axle:To match the design clearance ,keep the bearing horizontal and insert the bearing into the bearing bracket or axle.If it is hard to install,use a rubber hammer to slightly hit every part of the bearing,so that the bearing can be attention to the hitting force is too large.Afterwards,the matching status of bearing and basic face can be examined by checking the noise.For a interference fit,use heating or cooling to expand or shrink the parts for ease of installation. Be sure the bearing temperature does not exceed 80℃ . If the split inner or outer ring is acentric, please loosen the blots slightly and rotate the monolithic ring to adjust the concentricity of split ring, so that the bearing can be fit in the bracket.

3.Install the mounting disc:Place the mounting disc onto the bearing and align the screw holes, Screw all the bolts in the holes first and follow the orders show in below diagram when tightening bolts in diagonally opposite sequence,Do not tighten bolts randomly.

 

 

Cautions:

1.The normal operating temperature of Crossed roller bearing is 10-80℃, If it is over this range,please contact LDB.

2.If a foreign substance enters inside the bearing structure, the rotation route of the roller may be damage, or the bearing may fail.Please clean the bearing by refill the lubricant grease.

3.Please do not remove or apply force to the bolt and nut of the split bearing
