Is it normal for the threaded head to protrude from the bearing end face?

It is normal, and there is no specific restrictions regarding the size of the protruding part. During installation and use, attention should be paid to interference with the equipment.

Why are bearings rusted during use?

If a steel bearing is used, the bearing surface is prone to rusting due to the lack of surface treatment. If you have anti-rust requirements, please choose products with both bearings and shafts made of stainless steel.
