We are offering zys high precision yrt50 rotary table bearings for indexing tables and swivel type milling heads. Zys precision yrt bearings consists of thrustradial housing washer, a thrustradial shaft, two axial needle roller and cage assemblies and a group of radial cylindrical roller. They can support radial loads, axial loads from both sides and tilting moments without clearance and are particularly suitable for bearings arrangements with high requirements for running accuracy. Due to the fixing holes in the bearing rings, the units are very easy to fit. The bearings are radially and axially preloaded after fitting. bearing features: 1. high precision: precision at p4, p2. 2. high rigidity: yrt series bearings are with preload. 3. high speed: yrts series bearings can be applied in the high speed working condition. 6. Regular stock list: yrt50, yrt80-tv, yrt100, yrt120, yrt150, yrt180, yrt200, yrt260, yrt325, yrt395, yrt460, yrt580, yrt650, yrt850, yrt950, yrt1030, yrt1200 zys high precision yrt50 rotary table bearings model number: yrt50 type: high precision rotary table bearings brand name: zys material:gcr15 bore size:50 mm outside diameter: 126 mm width: 30mm place of origin: china precision: p4, p2 packing details: water-proof packing, single plywood case application: rotary tables, face plates, indexing tables, milling heads and reversible clamps, face plates, machine tools, measuring system etc.

We are offering precision angular contact ball bearings. Zys b7208thq1 precision angular contact ball bearings for spindles the zys precision angular contact ball bearings for spindles, have four size series, 718, 719, 70 and 72. With the same inner diameter, the outer diameters and the widths of 718, 719, 70 and 72 series increase in turn. zys precision angular contact ball bearings with 15â°(c) and 25â°(ac) contact angles. As for the angular contact ball bearings, the bigger the contact angle is, the greater the axial load capacity is, but the lower the limited speed of bearings becomes. Therefore, the spindle, with high speed and small axial load, should adopt the 15â° angular contact ball bearings, whereas the 25â° angular contact ball bearings should be adopted. the inner ring, outer ring and rolling element of rolling bearing under normal operating conditions are made of high carbon chromium bearing steel, but the steel bearings cannâ��t meet the requirements of such special conditions as high speed, wear-resisting, low temperature rise, long life, high reliability, etc., then si3n4 ceramics are believed to be present optimum rolling bearing materials to replace bearing steel. zys also offers widely used hybrid angular contact ball bearings for spindles in high-speed precision machine tools and other high-speed precision machines, that is, the inner and outer rings are made of high-quality bearing steel materials, while the rolling elements are made of si3n4 ceramics. compared to the angular contact ball bearings made of steel, hybrid angular contact ball bearings with the same structure and size have high speed, high rigidity, low friction heat, long life, etc. zys precision hybrid bearings with ceramic balls(hq1) can significantly improve the speed, rigidity, reliability and productivity of machine tools, and greatly reduce the friction heat, then extend the service life of host machine, etc.
