SKF 3307 Series Angular Contact Ball Bearing, 35mm Inside Diameter, 80mm Outside Diameter - 3307 ATN9
This angular contact ball bearing supports radial and axial loads in combined-loading applications within automation, electrical and mechanical systems. It is a double-row configuration designed for installations requiring parallel bores and open-end access, offering a balance of rotational performance and load capacity for medium-duty machinery.
Features and Benefits:
• 54 kN dynamic load capacity for sustained operational stress relief
• 38 kN static load capability to resist Peak or shock loads
• 30° contact angle for effective axial load transmission
• Non-metallic cage reduces noise and minimises friction
• CN internal clearance for controlled preload and shaft alignment
• 8,500 r/min maximum speed for high-speed rotating assemblies
• 38 kN static load capability to resist Peak or shock loads
• 30° contact angle for effective axial load transmission
• Non-metallic cage reduces noise and minimises friction
• CN internal clearance for controlled preload and shaft alignment
• 8,500 r/min maximum speed for high-speed rotating assemblies
Applications
• Suitable for spindle support in automated assembly equipment
• Ideal for shaft guidance in precision motors and drives
• Used for rotor support in electrical machines with axial forces
• Can be used for bearing seats in conveyor drive systems

What bore type does it accommodate and why does that matter?
It fits a parallel bore shaft which simplifies mounting and ensures uniform contact across the inner race for accurate alignment.
How does the cage material influence maintenance intervals?
The non-metallic cage lowers wear against rings and balls, which can extend lubricant life and lengthen inspection intervals under normal operating conditions.
What internal clearance classification is provided and how does it affect preload?
The CN internal clearance affords a NEUTRAL gap suitable for standard thermal expansion, allowing predictable preload settings without excessive axial play.
What outer geometry should housings provide for proper fit?
Housings require a plain outer-race seating to ensure even load distribution across the outer ring and to maintain the designed contact geometry during operation.
