Our factory uses military armor bearing steel (ZGCr15), US Saint-Gobain ceramic balls, and De Kruber grease. During the production of P4 and P2 precision, CNC engraving machine spindle bearings, CNC drills, milling machine spindle bearings, etc. Our factory produces high-speed precision motors, engraving machine spindle bearings, military quality, high reliability, high precision, low noise, the company strictly implements international quality, the application of bearing materials, product design, bearing cold and hot processing technology, bearing testing Technology, bearing accuracy and other aspects are at an internally good level. Manufacturers directly supply, the price advantage is obvious.

Quality Standard

Rockewell Bearings has added parameters that are not defined by ISO/ABEC for customers, including preload tolerances, functional tests, traceability and micron codes, cleanliness, raceway curvature, balls, etc. and roundness, surface processing (function And non-functional surfaces), steel specifications, cage trim and design, and installation chamfering. The definition of these parameters improves the quality of precision angular contact ball bearing products, thereby improving the performance of machine tool spindles.
The element of precision angular contact ball bearings is the cage, which is very important for machine tool bearings. The performance of the cage will affect the stability of machine tool bearings under high-speed rotation. The standard cage produced by Rockewell is made of phenolic resin. The internal design and the tolerance of the pocket gap are tight and the guide surface is controlled to ensure the stability of the cage during high-speed operation, lubrication and dynamic load.
The two elements of precision angular contact ball bearings are cleanliness, which is very important for precision angular contact ball bearings. Generally, the parts of the bearing products must be cleaned with a multi-solvent for 3 hours to prevent impurities from entering the bearing and prevent inherent pollution sources. In addition, the non-working surface of the bearing must be ground to ensure that the bearing is free of impurities before leaving the factory. Therefore, the bearing products produced by Rockewell can increase the normal operating time of the machine tool.
There are two main structural design methods for precision angular contact ball bearings: the high-rigidity WI series and the high-speed HX series to meet the requirements of different applications. The basic, open Rockewell bearing design has a higher spindle speed and greater dynamic radial stiffness, so the spindle can cut more material in a shorter time while ensuring excellent finished product tolerances. These improvements are attributed to the combination of the ball body and the precision engineering design of the raceway profile, which improves the processing rate.
