YRT bearing consists of a thrust/ seat ring, a thrust/ shaft washer, a thrust gasket, two needle roller cage components, and a set of radial cylindrical roller. Seat ring and shaft washer has uniform mounting screw holes. This type of bearing has high axial and radial load capacity, high rigidity and high precision, suitable for rotary table, chuck, iron head, and bearing device in measurement and test. This type of bearing has a higher requirement for matching equipment parts. The torque of the mounting screw should be controlled when installing.

Bearing characteristics:

High accuracy: the accuracy can reach p4, p2 level

High rigidity: this series bearing all has pre-load

High load: they can withstand radial load, axial load and torque load

High speed: YRTS series bearings can be used in high-speed working conditions
 

*YRTS bearing has high limit speed and low stable friction torque, this bearing is especially suitable for the engine with torque.

*Widely used in precision rotary table vertical grinding machine, dividing head, gear machine, milling machine shaft and other precision equipment.
*YRTS120-580, with 6 times rotate speed than YRT series. suitable for direct drive shaft bearing arrangement, especially suitable for using with torque motor.

Note:
1) including fixed screw and screw tapping hole.

2) the installation of screws

3) the bearing friction torque should be measured at 5r/min speed, and the starting friction torque should be 2-2.5 times the data of the table column
