Three-Row Roller Yrtm Rotary Table Bearing for Precision CNC Rotary Table Indexing Head

We are a professional manufacturer with our own export team. We control production, quality and delivery directly, so you get competitive price and reliable service.

YRT is the standard series with basic combined thrust/radial capability. YRTS features a brass cage on the radial rollers for higher limit speed and lower friction torque. YRTM adds an integrated angle measuring system (steel/magnetic grating) for closed-loop angular position control, making it ideal for high-precision applications requiring real-time angle feedback.

Yes. The non-contact measurement system and sealed bearing design make YRTM bearings suitable for Class 100 to1000 cleanroom applications, including semiconductor and optical equipment.

Yes. We offer custom YRTM bearings with bore diameters ranging from 100mm to 1030mm, and can accommodate special preload requirements, custom seal configurations, and bespoke signal output formats.

Installation screws must be tightened to the specified torque values (typically 14 Nm for M8 screws, 34 Nm for M12 screws). Incorrect torque will affect bearing preload and performance. We provide detailed torque tables with each shipment.
