Overview
The SKF 7215BG is a precision-grade angular contact ball bearing engineered for industrial automation, motion control, and mechanical power transmission systems. This single-row configuration combines radial and axial load capacity in one compact unit, making it a trusted replacement for original equipment and maintenance applications.
Key Features
- Single-row design accommodates combined radial and axial loads in one direction
- High-speed capable with precision ball-to-raceway contact geometry
- 52100 bearing steel construction for durability and load carrying capacity
- Standard ABEC-3 tolerance class suitable for general industrial use
- Open type (unsealed) design for applications requiring custom lubrication strategies
Technical Specifications
- Bore Diameter (ID): 75 mm
- Outer Diameter (OD): 130 mm
- Width (Height): 25 mm
- Bearing Type: Single-row angular contact ball
- Material: 52100 bearing steel
- Tolerance Class: ABEC-3
