Thin Section Ball Bearings are designed for applications where space is highly constrained.As indicated by the name, these bearings feature a minimized radial section—meaning the difference between the inner and outer ring diameters is reduced.This design allows for compact installation while maintaining functionality for light radial, thrust, or combined loads. This item is a 6820-2RS Thin Section Ball Bearing with metric dimensions of 100 mm bore diameter, 125 mm outer diameter, and 13 mm width.It is constructed from 52100 steel, features rubber seals (RS), has ABEC-1 grade, C0 internal clearance, and is pre-lubricated with grease.It is compatible with applications requiring the 6820, 6820RS, or 61820 RS bearing designation.The compact profile reduces required mounting space compared to standard 6000 series bearings.Sealing options include rubber sealed (2RS) configuration.The low sectional area contributes to low running torque.
