Introduction

BER10/19 Ultra-high-speed Series

The bearing can correspond to high-precision, ultra-high-speed rotation with an inner diameter of less than 30mm, making it compact
Draw high-performance and high-function series products.
Features: A wide sealing ring, compared with open bearings, the grease life is increased to 1.7 times, realizing a long life. The use of heat and abrasion resistance is very good, to achieve high speed, long
life. The standard adopts high-precision specifications.

Details

Structural point: Adopt small ball design, with high-speed performance, high rigidity and low heat generation.
Ring material: Imported IQ high-purity bearing steel, combined with special heat treatment process, cold treatment process and material modification technology, greatly improve the fatigue life of this series of bearings.
Contact angle: 30°(BAR10 series) and 40°(BTR10 series), bearing width dimension is special; bearing outer diameter deviation is specially treated, so that there is a gap between the outer diameter of the bearing outer ring and the inner diameter of the housing, that is, no radial load , Can only bear axial load; the assembly method is back-to-back installation.
Cage: Ball-guided nylon cage; it can work stably under 120ºС for a long time.
Rolling elements: steel balls (BAR10S; BTR10S) and ceramic balls (BAR10H; BTR10H).

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.
