6303ZZ deep-groove ball bearing

This single 6303ZZ deep-groove ball bearing measures 17 mm bore, 47 mm outer diameter and 14 mm width. It suits maintenance tasks or light assemblies that require a standard metal-shielded carbon-steel bearing.

Metal shields handle normal heat and noise

The carbon-steel races and ZZ metal shields tolerate typical operating temperatures without extra cooling. Friction stays low under normal loads, so audible noise remains minimal and no additional power draw is introduced.

Questions about this item

How do I press-fit the 6303ZZ bearing onto a 17 mm shaft without damaging the metal shields?

Use a sleeve that contacts only the inner ring, press evenly until the inner face seats against the shaft shoulder, and never hammer the outer ring or shields.

When should I replace the 6303ZZ bearing if the metal shields stay intact but the grease degrades?

Replace it once vibration or temperature rise signals lubricant breakdown, typically after the rated fatigue life for the 47 mm outer diameter and 14 mm width.
