3308 C3 NSK Double Row Angular Contact Ball Bearing 40mm x 90mm x 36.5mm
The 3308 C3 NSK Double Row Angular Contact Ball Bearing is a robust, precision-engineered bearing designed to handle demanding combined radial and axial loads in high-speed industrial applications. This double row configuration delivers exceptional rigidity and load capacity, making it an ideal choice for heavy-duty equipment requiring superior performance and reliability.
Design & Functionality
Double row angular contact ball bearings are specifically engineered to accommodate simultaneous radial and axial loads with enhanced load-carrying capabilities compared to single row designs. The dual row arrangement provides increased rigidity and improved load distribution, making it particularly suitable for applications where both high speeds and significant loads are present.
Key design features include:
- Double row angular contact configuration for superior load capacity and rigidity
- Contact angle of 30-40 degrees for efficient load distribution across both rows
- Slightly increased radial clearance for accommodating thermal expansion and operational tolerance
- Open seal type (none) for applications where external lubrication management is preferred
- Steel cage construction for reliable performance under heavy-duty conditions
- Standard bearing steel construction for exceptional durability and longevity
- Tolerance class P0/PN2 (ABEC 1) for precision engineering standards
- Compact 40mm bore size ideal for space-efficient installations
