Dentail

The HCB70 - EDLR - P4S series of high - speed spindle bearings are produced by Luoyang Rockwell Precision Bearing Manufacturer. After adjustment, they are paired or grouped, with a contact angle of 25°, using ceramic balls and reaching P4S tolerance level. They are suitable for direct oil feeding through the outer ring and equipped with embedded O - rings. This design enables them to balance radial and axial loads. The ceramic balls are wear - resistant, reduce centrifugal force and ensure dimensional stability. The high - precision tolerance and elaborate lubrication and sealing design guarantee their performance.

Excellent high - speed performance: It can achieve extremely high rotational speeds, meeting the high - speed milling requirements of advanced manufacturing in aerospace and other fields.
Ultra - high precision: With extremely small radial and axial errors, it ensures the precision of precision machining, suitable for industries such as optical lens grinding.
Long service life: The ceramic balls, combined with good lubrication and sealing design, extend the service life and reduce maintenance costs, suitable for continuously operating production lines.
Strong stability: With balanced load distribution, it remains stable in the face of complex working conditions, improving the efficiency and reliability of processing equipment.

Application

The bearings can be used in the following industries

Aerospace: Facilitates the high - quality processing of aerospace engine blades and other components.
Precision machinery processing: Enables the precise movement of cutting tools in grinding machines and machining centers to process precision molds and other parts.
Electronic information: Provides stable support for semiconductor chip manufacturing and other processes, ensuring the quality of electronic products.
Medical devices: Used in the production of high - end medical devices to improve manufacturing precision.
