YRT bearing is a high precision, low torque, the combination of long-life bearings. Structure consists of an outer and two inner rings, two cages and three-row roller composition, seat and shaft ring have uniform mounting screw holes. Which constitute two-row roller thrust load can withstand two-way bearing, the third-row roller radial play a guiding role. Its accuracy is divided into two kinds of normal level and the compression level. The bearing has a compact, wall thickness, light weight, stiffness, high rotational accuracy, large load capacity, starting friction torque, more than the number of mounting holes and other characteristics, but also has a higher radial and axial load carrying capacity for high precision indexing plate, machine tools or precision machinery, such as rotary table configuration. Traditional indexing plate bearing three most common action need only ensure its axial, radial precision, large volume, heavy weight, supplies and more, this set can meet the high precision bearings indexing rotation requirements. When installing the screw tightening torque for certain requirements. Series Model: YRT50, YRT80, YRT100, YRT120, YRT150, YRT180, YRT200, YRT260, YRT325, YRT395, YRT460, YRT580, YRT650, YRT850, YRT950, YRT1030, YRT1200 temperature range: -30 ℃ to 120 ℃. Scope: widely used in precision equipment precision turret vertical grinder, dividing head, hobbing machine, milling machine the workpiece shaft. Table, chuck, blade iron, vertical grinder.
