1311 Self Aligning Ball Bearing 55x120x29mm

1311 Self Aligning Ball Bearing 55x120x29mm
✔️ Designed for misalignment and smooth tracking

This is a single 1311 self-aligning ball bearing (pack of 1) built with a spherical outer raceway so the inner ring and balls can naturally compensate for shaft misalignment or mounting imperfections. It’s commonly used in applications where flexing, vibration, or deflection would stress a standard bearing.

✅ Inner diameter: 55mm
✅ Outer diameter: 120mm
✅ Width: 29mm
✅ Type: self-aligning
✅ Dynamic load rating: 51,500 N
✅ Static load rating: 17,900 N
✅ Max grease speed: 5,000 rpm
✅ Max oil speed: 6,300 rpm
✅ Quantity: 1 bearing

💡 Why do self aligning bearings work better in applications with shaft deflection?
They use a spherical outer raceway that lets the inner ring float slightly without binding.
- This prevents edge loading during misalignment
- Reduces friction when shafts flex under load
- Keeps rotation smooth even with imperfect mounting

If your build needs a bearing that can deal with real-world misalignment instead of fighting it, this one is a smart pick, drop one in and enjoy smoother motion without headaches.
