How to read a bearing designation

Break a designation into type, dimension series, bore, sealing and clearance suffixes without guessing.

Understand P0, P6, P5, P4 and P2 classes and why ABEC equivalence is never a complete substitution.

Clearance is an operating condition, not just a suffix. Fit, temperature and preload change residual clearance.

Compare contact seals, non-contact shields and open bearings by friction, speed and contamination.

Steel, brass, polyamide and PEEK cages have different temperature, speed and lubrication boundaries.

Avoid damaging raceways through uncontrolled press force, induction heating or excessive axial preload.

Separate evidence from assumption using load path, lubricant condition, mounting marks and damage morphology.
