These are notches cut into the inner and outer rings so that ​extra balls can be inserted​, creating a full complement bearing with no cage. This increases radial load capacity compared to standard bearings.

1.Higher radial load capacity due to more balls in the raceway. 2.Suitable for heavy-load, low-speed applications where space and load bearing are priorities.

1.Axial load capacity is limited​—they're primarily radial-load bearings. 2.Cannot handle high rotational speeds like standard deep groove bearings. 3.Ring slots create slight stress concentrations, reducing overall strength mildly.

1.Radial load life improves due to ball count increase 2.Axial and dynamic fatigue life may reduce slightly from stress risers at slot edges 3.Generally, they outperform standard bearings in radial-heavy roles and under moderate speeds.

1. Shielded or sealed versions typically come factory-lubricated for life, with no need—or ability—for relubrication. 2. Open-slot bearings must be lubricated during assembly; maintenance lubrication may be applied depending on the application.

Highly suited for heavy radial, low-speed uses—e.g.: 1.Agricultural machinery 2.Gearboxes 3.Pumps 4.Fans and conveyors

Choose filling-slot versions when​: 1.The application has high radial loads 2.Operates at lower speeds 3.Axial loads and high-speed performance are uncritical ​Avoid if: Need to carry axial loads or rotate at high RPMs—standard caged bearings are better.
