Bore – The diameter of a bearing’s shaft. The bore is also called the
inner diameter (ID)
Dynamic – lbs capacity while spinning or rotating
OD – Outer Diameter. Diameter of outer circle
Open Bearings – Not shielded or sealed
Radial load – Every ball bearing meets a specific load requirement–radial load is perpendicular to the shaft
Sealed Bearings – Completely sealed
Shielded Bearings – Not completely sealed—the shield is connected to the outer race with a clearance between it and the inner race
Static – lbs capacity while not spinning or rotating
Thrust load – Every ball bearing meets a specific load requirement—thrust load is along the line of the shaft
Weight – Weight of single bearing in lbs
Width – Thickness of bearing
Ball bearing – A bearing containing small metal balls held between an inner and outer ring to maintain separation between the moving parts. It is a low-friction or anti-friction bearing. Ball bearings support the shaft in a set position to allow the shaft to rotate. Ball bearings produce excellent resistance to wear and the best load carrying ability.
