Overview
The FAG 7228B.MP.UA is a single row angular contact ball bearing engineered for applications requiring simultaneous radial and axial load capacity. This bearing features modified internal construction, a solid brass cage, universal design, and small axial internal clearance. The bearing has metric dimensions of 140mm bore, 250mm outside diameter, and 42mm width. It is manufactured to DIN 628-1 standards and is suitable for machinery where combined loads and high rigidity are critical.
Key Features
- 40° contact angle to DIN 628-1 specifications
- Solid brass cage with universal design for pairing in X or O arrangements
- Supports high radial forces and axial forces in one direction; greater contact angle provides higher axial load capacity
- Brass cage design for optimal ball guidance and minimal wear
- Solid inner and outer rings for structural integrity
Technical Specifications
The bearing’s core dimensions and load ratings are as follows:
- Basic dynamic radial load rating: 214,000 N; Basic static radial load rating: 231,000 N
- Fatigue load limit (radial): 11,500 N
- Maximum rotational speed: 4,800 rpm
- Operating temperature range: -30°C to +200°C
- Weight: 8,695 kg
Typical Applications
The FAG 7228B.MP.UA is particularly suitable for applications where bearing arrangements must support combined loads (radial and axial simultaneously), moderate to high loads are present on one side, rigid axial guidance is required, and the arrangement must be axially clearance-free or preloaded. Common uses include:
- Spindle bearings in machine tools
- Gearbox and transmission assemblies
- Industrial pump and compressor shafts
- Automotive and aerospace equipment
- High-speed rotating machinery
