3309 ANR/C3 SKF Angular Contact Ball Bearing 45mm x 100mm x 39.7mm
3309 ANR/C3 SKF Double Row Angular Contact Ball Bearing
This premium SKF double row angular contact ball bearing is engineered to deliver exceptional performance in demanding applications requiring simultaneous radial and axial loads. The 3309 ANR/C3 combines robust construction with precision engineering, making it an ideal choice for high-speed industrial equipment and machinery requiring reliable load handling in both directions.
Design & Functionality
As a double row angular contact bearing, this model features raceways in both the inner and outer rings that are angularly displaced along the bearing axis. This innovative design enables efficient handling of combined radial and axial loads acting simultaneously, while the double row configuration provides:
- Superior load capacity compared to single row variants
- Accommodation of axial loads in both directions
- Exceptional stiffness and stability in heavy-duty applications
- Capability to withstand tilting moments
- Compact axial footprint with double row performance
Key Features:
- 30° contact angle optimized for balanced radial and axial load distribution
- Sheet steel cage construction for reliable ball guidance and durability
- Slightly increased radial clearance for flexible installation requirements and thermal expansion accommodation
- Open bearing design (unsealed) allowing for custom sealing solutions or specific lubrication methods
- Outer ring with groove and circlip for secure axial positioning and mounting versatility
- P6/ABEC 3 tolerance class for precision performance in demanding applications
- Extended temperature range of -20°C to +150°C for diverse operating environments

Why Choose SKF?
SKF is the world's largest bearing manufacturer, renowned for exceptional quality standards and precision engineering. SKF double row angular contact bearings are trusted in high-speed applications and heavy-duty equipment where reliability and performance cannot be compromised.
Typical Applications:
Ideal for gearboxes, machine tool spindles, pumps, electric motors, and other precision machinery requiring combined radial and axial load handling. The circlip groove design makes this bearing particularly valuable for applications demanding secure axial positioning and simplified mounting. The slightly increased clearance provides flexibility for applications with thermal variations or where precise preload control is required. This bearing is well-suited for both standard industrial environments and temperature-sensitive applications within its operating range.
