machine tool spindle bearing material
With the continuous improvement of the requirements of the spindle speed of the machine tool spindle, on the one hand, the internal structural design of the bearing is improved, and on the other hand, the new bearing material is developed. At present, hybrid ceramic ball bearings made of silicon nitride ceramic as rolling elements have been widely used in the field of high speed machine tools.This article from QIBR official website, for reproduced, please specify from this website www.qibr.com!
2017-01-05Effect of heat treatment on bearings
1.The quality of heat treatment directly affects the life of the bearing.If the heat treatment temperature is too high, that will result in coarse grains and quench cracks. on the contrary,If the quenching temperature is too low, the hardness of the bearing will be slightly reduced. 2.If the tempering temperature is too high, the hardness will decrease and the stress relief will be better.The tempering temperature is too low, the hardness of the material is high, but the stress is difficult to re…

The microscopic defects of steel include various non-metallic inclusions, carbon segregation, carbide network and ribbon, and annealed tissue unevenness in the steel that can be found under the optical microscope. Including pits, cracks, folds, cracks, scratches, crusting and slag inclusions found on the surface appearance inspection, as well as shrinkage holes, subcutaneous bubbles, white spots, over-burning, central looseness, general Loose and segregation, surface decarburization, etc. These a…
2016-12-07Robot bearing
As one of the key components of industrial robots, industrial robot bearings are most suitable for joints or rotating parts of industrial robots, rotary tables for machining centers, robot rotating parts, precision rotary tables, medical instruments, measuring instruments, and IC manufacturing. Wide range of applications such as devices. It mainly includes two types of bearings for industrial robots, one is a thin-walled bearing with equal section, and the other is a crossed cylindrical roller be…
2016-12-02General bearing type introduction
1. Deep groove ball bearing: It is simple in structure and easy to use. It is the most widely used type of bearing. These bearings have a small friction factor and a high limit speed. 2. Self-aligning ball bearings: Mainly bearing radial loads, and can withstand a small amount of axial load while receiving radial loads. 3. Angular contact ball bearings: The limit speed is higher and increases as the contact angle increases. 4. Cylindrical roller bearings: A generally radial load, o…
