SKF Self-aligning ball bearings Series Ball Bearing, 35mm Inside Diameter, 80mm Outside Diameter - 2307 ETN9/C3
This ball bearing is a two-row self-aligning unit designed to accommodate shaft misalignment and support radial loads in rotating assemblies. It features steel balls with a cylindrical bore and an open end, intended for applications where angular displacement between shaft and housing can occur while maintaining smooth rotation at elevated speeds.
Features & Benefits
• 39.7 kN dynamic load capacity for sustained radial loading
• 11.2 kN static load rating to resist heavy stationary loads
• Permissible angular misalignment 3° to absorb shaft deviation
• Limiting speed 12,000 r/min for high-speed operation
• Non-metallic cage reduces friction and minimises maintenance
• C3 internal clearance to allow thermal expansion under service
• 11.2 kN static load rating to resist heavy stationary loads
• Permissible angular misalignment 3° to absorb shaft deviation
• Limiting speed 12,000 r/min for high-speed operation
• Non-metallic cage reduces friction and minimises maintenance
• C3 internal clearance to allow thermal expansion under service
**Applications**
• Suitable for conveyor drive systems with shaft deflection
• Ideal for motor and gearbox assemblies in automation
• Used with electrical motors requiring high running speed
• Can be used for rotating equipment in electronics production
• Suitable for bearings in mechanical actuators and linkages

What seating tolerances should I consider for mounting?
Use standard seat tolerances
recommended d1 ≈ 46.7mm and D1 ≈ 67mm Interface dimensions support appropriate fits for normal conditions.
How does mass affect dynamic behaviour in precision systems?
The bearing mass is 0.68kg, which influences rotor balance and inertia during acceleration and deceleration phases.
What are the abutment limits for housings and shafts?
Minimum shaft shoulder diameter da min is 44mm and maximum housing bore Da max is 71mm with fillet allowance ra max 1.5mm.
Which calculation factors assist fatigue and life estimates?
Use factors such as kr 0.05, e 0.46, Y0 1.4, Y1 1.35 and Y2 2.1 when performing bearing life and load distribution calculations.
