7256-B-MP-UA FAG Single Row Angular Contact Ball Bearing 280mm x 500mm x 80mm

7256-B-MP-UA FAG Single Row Angular Contact Ball Bearing

This premium single row angular contact ball bearing from FAG is engineered to deliver exceptional performance in large-scale industrial applications requiring simultaneous radial and axial loads. With a substantial bore diameter of 280mm and outer diameter of 500mm, this heavy-duty bearing is designed for high-speed precision machinery where reliability and load capacity are critical. The bearing pair configuration with low axial clearance in both O- and X-arrangements provides versatile mounting options for demanding industrial environments.

Design & Functionality

Single row angular contact ball bearings are specifically designed to handle combined radial and axial loads acting in one primary direction. The 7256-B-MP-UA features a 40° contact angle that optimises load distribution and provides superior axial load capacity in a single direction, making it ideal for applications where unidirectional load support is required. The open design with no seals allows for straightforward maintenance and lubrication accessibility in demanding operational scenarios.

The bearing pair arrangement with low axial clearance offers exceptional flexibility, allowing configuration in both O-arrangement (back-to-back) and X-arrangement (face-to-face) depending on specific application requirements. This versatility eliminates the need for custom bearing solutions, simplifying installation and reducing overall system complexity.

Applications

The 7256-B-MP-UA is ideal for large-scale industrial applications including heavy-duty gearboxes, industrial electric motors, spindle systems, compressors, pumps, and other precision machinery where high-speed operation combined with significant unidirectional axial loads is essential. The generous bore and outer diameters make this bearing particularly suited for large rotating equipment in industries such as mining, cement production, power generation, and heavy manufacturing.

The bearing pair configuration with low axial clearance provides exceptional versatility, allowing mounting flexibility in both O-arrangement (back-to-back for load support in opposite directions) and X-arrangement (face-to-face for load support in the same direction). This configurability makes it an excellent choice for applications requiring precise axial load management without the expense of custom bearing solutions. The brass cage construction and open design ensure excellent performance in environments where lubrication accessibility and long-term reliability are critical considerations.

FAG angular contact bearings are recognised globally for their exceptional quality standards and durability, making them the preferred choice for the most demanding industrial applications requiring large-format precision bearings.
