The Guide bar rollers are a kind of rolling bearing, and are one of the most widely used parts in modern machinery. Guidebar rollers rely on rolling contact between the main components to support rotating parts. Roller bearings are now mostly standardized. Roller bearings have the advantages of small starting torque, high rotation accuracy and convenient selection.

The Guide bar rollers are a kind of rolling bearing, and are one of the most widely used parts in modern machinery. Guidebar rollers rely on rolling contact between the main components to support rotating parts. Roller bearings are now mostly standardized. Roller bearings have the advantages of small starting torque, high rotation accuracy and convenient selection.

　　Guidebar rollers rely on rolling contact between the main parts to support rotating parts. Different roller bearings can bear different radial and axial forces. When selecting roller bearings, the choice should be made according to the specific working conditions.

　　The Guide bar rollers are the characteristics of an inner ring integrated with the outer ring. Guide bar rollers are cylindrical rollers in a 90-degree V-shaped groove rolling surface through the isolation block is perpendicular to each other, so the Guide bar rollers can withstand radial load, axial load and torque load and other multi-direction load. The size of the inner and outer rings is miniaturized, and the extremely thin form is close to the limit of small size, and has high rigidity, and the accuracy can reach P5, P4, P2. It is suitable for parts requiring high precision of inner ring rotation.

　　Rollers installation introduction:

　　I. Inspection of parts before installation of Guide bar rollers

　　Clean the bearing seat or other mounting parts thoroughly and check for burrs or burrs.

　　Two, the Guide bar rollers into the shaft or bearing seat

　　Because the thin wall bearing is easy to tilt when loaded. In order to prevent this phenomenon, please keep the level while beating evenly with a rubber rod, and carefully load the cross roller bearing into the bearing seat or shaft bit by bit until it is confirmed by sound and the datum level is completely close.

　　Three, Guide bar rollers fix the installation of flanges

　　(1) Place the fixed flange on the cross roller bearing. Shake the fixed flange several times to match the position of the bolt hole.

　　(2) Insert the fixing bolt into the hole. When turning the bolt by hand, ensure that the bolt is not hard to screw in due to the deviation of the bolt hole.

　　(3) The locking of the fixed bolt needs to be tightened repeatedly from incomplete locking to full locking. When tightening the divided inner or outer ring, the outer or inner ring of the whole can be slightly rotated to correct the deviation between the inner and outer ring and the main body.
