Thin Section Deep Groove Bearings with their large complements of small diameter balls provide greater stiffness and lower torque while permitting a significant reduction in weight and space when compared to standard section bearings. These advantages have found wide acceptance in many critical applications including ordnance and are os pace guidance systems, large diameter encoders and radar support systems.

In some area, the bearing is required anti-friction & clean & well lubricated, then , double sealed or single deep groove bearings is optimal choice.
