Precision tapered roller bearings


              • ZYS single row tapered roller bearings can support radial load and axial load in one direction. The axial component force will be generated under the radial load, therefore, this bearing is often used with another tapered roller bearing in conjunction. Taper roller bearings can bear large axial load, but its speed performance is low. In addition, due to the separable inner and outer ring, mounting and dismounting tapered roller bearing are very convenient. Tapered roller bearings have tapered inner ring and outer ring raceways, and tapered rollers are arranged between the two rings. The projection lines of all conical surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for the combined load of radial and axial loads. The axial load capacity of taper roller bearing is mostly determined by the contact angle α; the larger the angle α, the higher the axial load capacity. The size of the angle is expressed by the calculation factor e; the greater the value of e, the greater the contact angle, the greater the applicability of the bearing to bear axial loads. This type of bearing is divided into single row, double row and four row tapered roller bearings according to the number of roller rows. Tapered roller bearings are widely used in automotive, rolling mill, mining, metallurgy, plastic machinery and other industries.

                The most commonly used taper roller bearings in machine spindles are ZYS 32000 dimension series. Features of ZYS tapered roller bearings: 1. Bearing inner and outer ring Made of high-quality bearing steel raw materials. With advanced heat treatment process, it effectively extended bearing service life. 2. Rolling body With optimized design of rolling surface number curve, higher reliability and stronger bearing capacity can be achieved. 3. Bearing cage The stamped steel plate material effectively reduces the frictional heat between the rolling elements and the load is evenly stressed.
