Flange Type Screw Bearing

Advantages of Flanged Screw Bearings

1. The outer ring used for the integral flange can be directly installed on the fixed end, which solves the problem of high technical requirements for the installation of ordinary 7 types of bearings. The company can customize the flange structure according to customer requirements.

2. Flange-type screw bearing has a compact structure and small size, can be subjected to two-way force, has low vibration, low noise, high rotation accuracy, low friction torque, excellent sealing performance, high-speed operation performance, wide adaptability, and easy installation , And the characteristics of price and long life.

Installation Notes:

The flange-type screw bearing unit is used to replace a pair of common single-row matched bearing structural parts, which saves the bearing seat, sealing ring, bushing, end cover and grease. Only locking bolts are required, no adjustment is required, and the installation is simple and convenient, and improves The assembly precision reduces the cost and improves the efficiency.

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.
