Product Description

Slim ring Crossed roller bearing RA12008 (120x136x8) Thin Section Type Replace 

 (Separable Outer Ring, Type for Inner Ring Rotation)

BYC RA12008 Crossed roller bearing are lightweight, compact bearings with thinnest possible inner and outer rings with high rigidity, because of its vertical arrangement of cylindrical rollers with a 90°V groove through the separate spacers in the deep groove rolling surface. This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads.

 

 RA12008 thin type is a small and light weight bearing with a very thin wall thickness. It carries heavy loads. Therefore, the bearing housing and pressure flange can be light weight. It is being used in rotary locations such as in robot hands. The outer rings of the RA thin type are separable and fixed by special rivets.

C. 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

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

 

D. Product Application

•Industrial Robotic arm,Reducer drive

•Percision Turntable,NC rotary table

•Rotation part of Machine tools

•Inspection instrument,Medical equipment

•Aero&Aviation equipment,Military radar etc

 

E. Installation & Cautions

Example of installation for Crossed Roller Bearings:

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 BYC.

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.

Packaging & Shipping

1. Industrial Neutral Packing,Package as your requirements.

2. Small size Bearings:Plastic vacuum packaging bag+Paper Box/Neutral Carton

3.Large size Bearings:Plastic film+Pergamyn paper+Roll tape+Wooden Box

4.Shipping:By air or By sea:DHL/TNT/UPS/EMS etc
