Radial “Deep Groove” Ball Bearings

Good for Smaller Spaces & When Axial Loads Move in Two Directions

Radial Ball Bearings are generally the most popular high precision bearing type used in industrial applications because of their versatility.

They are usually chosen over Angular Contact Bearings when:

• Support is needed for axial loads that move in both directions
• Bearing space is limited, therefore multiple sets of Angular Contact Bearings won’t fit
• Machine operates at low to moderate speeds (RPM)
