Product Description

Four-point angular contact ball bearings primarily accommodate pure axial loads or combined loads dominated by axial forces. A larger contact angle enhances bidirectional axial load capacity. As a special variant of single-row angular contact ball bearings, their separable inner ring design enables substitution for paired single-row angular contact ball bearings. Four-point contact ball bearings can simultaneously handle radial loads, bidirectional axial loads, and moment loads, operating stably at elevated rotational speeds.

Features and Advantages

● High bidirectional load capacity

The separable inner ring design permits increased ball packing, enabling not only higher radial load handling but also exceptional bidirectional axial load capacity.

● High operating speeds and stability

The minimal contact area between rolling elements and raceways minimises operational heat generation and ensures superior guidance, making them suitable for high-speed applications with a higher limiting speed than standard angular contact ball bearings.

● Compact, space-saving design

A single bearing provides bidirectional axial positioning, eliminating the need for paired installations. This significantly reduces axial space requirements, offers a compact structure, and accommodates equipment with limited installation space, enhancing assembly efficiency.

● Easy Installation and Versatility

The inner ring features a split-type dual-half structure, allowing separate installation with the outer ring (equipped with balls and cage). This facilitates straightforward disassembly, enables rapid and precise positioning, and adapts to diverse industrial applications.
