Product Description

 

PRODUCT DETAILS

The double-row thin-walled angular contact ball bearing, with its innovative structural design and advanced manufacturing techniques, has become a core component in the field of high-end equipment manufacturing. The exquisite thin-walled structure lies in the fact that by optimizing the material ratio and processing techniques of the raceway, it can maintain excellent compressive strength and fatigue resistance even when the thickness is only one-third of that of traditional bearings. This significantly reduces the overall weight and space occupation of the equipment, providing a crucial support for lightweight design. The precise arrangement of the double-row angular contact balls (with the contact angle customizable from 15° to 45°) forms a unique force balance system. It can precisely distribute radial and axial combined loads according to actual working conditions, effectively suppressing shaft deflection and ensuring the extremely high stability of the equipment operation.
