Cool How to fit Jewel Bearings ?

Hi All,

I am doing a project & using RING Jewel bearings to support a moving element.

Jewel Bearings fit on a shaft (with interference fit).

As jewel bearing are brittle in nature, i am scared that hammering bearing on to the shaft will create cracks & bearing may ultimately break.

Any suggestions or other routes to fit JEWEL in interference fit?

Thanks in advance.

I'd not use interference fits with these, but a 0.02mm clearance and a bond like loctite glue. I would think any press fit in these would fracture the jewel.

Cheers James.
