Slim Bearings or thin section bearings were used widely in the Textile printer, Medical devices, Rotary tables, Radar, Communication, Aircraft, Aerospace, Astronomy instrumentation, Industrial robotics, etc. characters such as small space, lightweight and low friction.

With their large complements of small diameter balls, Thin Section Deep Groove Bearings provide greater stiffness and lower torque while significantly reducing weight and space compared to standard section bearings. These advantages have found wide acceptance in many critical applications, including ordnance and aerospace guidance systems, large diameter encoders, and radar support systems. In some areas, the bearing is required anti-friction & clean & well lubricated, then, double sealed or single deep groove bearings is the optimal choice
