✔️ Durable sealed self-aligning ball bearing for misalignment, 1 piece
The 2307 self-aligning ball bearing is designed with a spherical outer raceway that lets the inner ring, balls, and cage align with misalignment. This makes it ideal for equipment where shaft deflection or mounting tolerances exist, delivering smooth, reliable operation under dynamic loads.
✅ Inner diameter: 35 mm
✅ Outer diameter: 80 mm
✅ Width: 31 mm
✅ Dynamic load rating C: 40,000 N
✅ Static load rating Co: 11,300 N
✅ Limiting speed (grease): 7,100 RPM
✅ Limiting speed (oil): 9,000 RPM
💡 What is a self-aligning ball bearing and why is it handy when alignment is off?
- It lets the inner ring, balls, and cage adjust to shaft misalignment, reducing binding.
- It supports smooth operation under dynamic loads in machines with mounting tolerances.
- It simplifies setup and maintenance in gearboxes, conveyors, and automated equipment.
