30313

The 30313 single row tapered roller bearing is engineered to manage high-capacity radial and axial loads simultaneously, thanks to its specialized metric dimensions of 65mm x 140mm x 36mm. Featuring a separable "cup and cone" design, this bearing allows for independent mounting of the inner ring (cone) and the outer ring (cup), significantly simplifying installation in heavy-duty machinery. Its internal geometry utilizes precision-ground tapered rollers and optimized raceways, ensuring even stress distribution across the contact surfaces to minimize friction and heat generation during high-speed rotations.

Built for durability in demanding environments, the 30313 bearing is typically manufactured from high-grade chromium steel (GCr15), offering superior wear resistance and extended service life for industrial gearboxes, automotive transaxles, and agricultural equipment. The unit excels in applications requiring high rigidity, as a pair of these bearings can be adjusted against each other to apply a specific preload, effectively controlling shaft deflection. With a dynamic load rating that supports rigorous mechanical stress, the 30313 remains a standard choice for engineers seeking a balance between high-load performance and operational reliability.
