7405-BCBM SKF Single Row Angular Contact Ball Bearing
7405-BCBM SKF Single Row Angular Contact Ball Bearing
This precision-engineered SKF angular contact ball bearing is designed for applications requiring simultaneous radial and axial load capacity. As a single row design, it offers reliable performance in high-speed, precision-demanding environments. The bearing pair configuration with low axial clearance provides exceptional stability and is ideal for both O- and X-arrangement preloaded mounting configurations.
Key Features:
- 40° contact angle for optimal load distribution and combined axial-radial load handling
- Bearing pair with low axial clearance in O- and X-arrangements for precision preloaded applications
- Brass cage design for lightweight, reliable operation with excellent cage guidance and reduced friction
- Open bearing design (no seals) allowing for flexible mounting, maintenance, and lubrication options
- SKF manufacturing excellence – a globally recognized bearing manufacturer known for superior quality and precision engineering
- Standard bearing steel construction for durability and long service life
- Normal radial clearance with P0/PN2 tolerance class (ABEC 1 standard)
- Extended operating temperature range from -20°C to +150°C for versatile application capability
