Bearings support rotation or linear motion and reduce friction — life-determining, 30-40% of equipment failures originate in bearings. SKF, Schaeffler (FAG/INA), NSK, NTN, Timken and Koyo lead — deep-groove, spherical roller, taper roller, thrust.

FAQ
Q Spotting SKF/FAG counterfeits?
A
Original outer-ring laser etching is crisp; packaging carries SAP serial + batch + anti-fake QR (SKF Authenticate, Schaeffler MEDIAS). Below 30% market price = counterfeit.
Q C0/C3/C4 clearance?
A
C0 standard (normal temperature, light load); C3 above standard (motors, VFD-driven with temperature rise); C4 larger (large motors, high temperature); C2 tight (precision spindles).
Q Hybrid ceramic balls?
A
Si3N4 with low density, low thermal expansion, corrosion-resistant — ultra-high-speed spindles (dn > 2e6), electrical isolation, vacuum. 2-4x cost, 3-5x life.
