Overview
The 7216BG angular contact bearing is a precision-engineered single-row ball bearing designed to handle combined radial and axial loads. With metric dimensions of 80 mm bore, 140 mm outside diameter, and 26 mm width, this bearing delivers reliable performance in demanding industrial applications requiring high-speed, high-precision operation.

- Single-row design for compact installation
- 40-degree contact angle optimized for axial load capacity
- High carbon chrome steel construction for durability
- Pressed steel cage for stable ball retention
- Open design—no seals or shields
- Non-separable bearing assembly

Typical Applications
Angular contact ball bearings are commonly used in machine tools, feed screw mechanisms, ball screw support units, pumps, compressors, gearboxes, conveyor systems, and industrial spindles. The 7216BG’s 40-degree contact angle provides excellent thrust capacity when loads are applied in one direction, making it ideal for applications where axial preload is required or where combined loads dominate. These bearings are often mounted in pairs to achieve bidirectional axial load capacity.
