Thin Section Ball Bearings are designed for applications where space is highly constrained.As the name suggests, these bearings have a minimized sectional difference between the inner and outer diameters, resulting in a compact and lightweight design.While this reduction in section thickness slightly limits load capacity, thin section bearings are still capable of supporting light radial, thrust, or combined loads.The 6808-2RS bearing is part of the 6800 series, which is suited for limited space applications with light loading requirements.It features a bore diameter of 40 mm, an outer diameter of 52 mm, and a width of 7 mm.Constructed from 52100 steel, this bearing includes rubber seals on both sides (2RS) to help retain lubrication and.It comes pre-greased and has a standard C0 internal clearance.The bearing meets ABEC-1 standards and weighs 33 grams per unit.Due to their small size and low sectional area, thin section bearings generate lower running torque compared to standard bearings.This contributes to improved efficiency in speed or energy-sensitive applications.The 6800 series offers a balance between compactness and load capability, making it suitable for such as robotics, medical devices, optical instruments, and aerospace systems.Available in various sealing configurations, including shielded, open, and sealed types, these bearings offer flexibility in lubrication and mounting options.The 6700, 6800, 63800, and 6900 metric series provide incremental differences in load capacity and dimensions to suit specific design needs.
