How to read a bearing designation
Break a designation into type, dimension series, bore, sealing and clearance suffixes without guessing.
ISO precision grades and ABEC cross-reference
Understand P0, P6, P5, P4 and P2 classes and why ABEC equivalence is never a complete substitution.
Internal clearance: CN, C3 and C4
Clearance is an operating condition, not just a suffix. Fit, temperature and preload change residual clearance.
Seals versus shields: 2RS, 2Z and open bearings
Compare contact seals, non-contact shields and open bearings by friction, speed and contamination.
Cage material selection
Steel, brass, polyamide and PEEK cages have different temperature, speed and lubrication boundaries.
