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.
