YRT Rotary Table Bearings
 | YRT basic rotary table bearings are designed with a radial full roller, two groups of axial needle roller, cage assembly, an out ring, an L-section inner ring, and the second ring. The out ring and inner ring are equipped with fixing holes, allowing the bolt to secure the bearings directly. The YRT rotary table bearing structure is capable of bearing double-direction axial load, radial load, and tilting moment. This series bearing has a preload applied prior to leaving the factory, eliminating the need for clearance adjustments during installation. This series bearing is particularly well-suited for applications requiring high precision, high stiffness, low speed, and a short rotate period, such as rotary tables, index heads, and revolving milling heads. This bearing offers axial and radial running precision to suit your specific requirements. |
Features
1. High precision: P4 precision, P2 precision
2. High rigidity: This series bearing have preload
3. High load:This series bearing can bear double-direction axial load, radial load and tilting moment
4. High speed: YRTS series bearing can be applied to the situation of high rotating speed
