C . YRT type Rotary Table Bearings Details
Product Features YRT bearings (rotary table bearings) are axial and radial combined cylindrical roller bearings, including two thrust needle roller bearings and a radial cylindrical roller bearing with the combination of axial and radial p reload, For the convenience of transportation and fixing, two or three symmetrical screws are fastened to the two rings in order to prevent rollers and rings generating collisions which influence bearing accuracy.
Series Introduction YRT bearings (rotary table bearings) are axial and radial combined cylindrical roller bearings, including two thrust needle roller bearings and a radial cylindrical roller bearing with the combination of axial and radial p reload, For the convenience of transportation and fixing, two or three symmetrical screws are fastened to the two rings in order to prevent rollers and rings generating collisions which influence bearing accuracy.

D . YRT type Rotary Table Bearings 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℃ .
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 YRT 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."
