low noise agitator/blender bearing 30305 taper roller bearing 30304

Tapered roller bearings can be separated, and the assembly consisting of the inner ring and the roller and cage, and the outer ring can be installed separately. Correcting the nip line where the rollers and track meet reduces stress concentrations.

If you want to know more details, please feel free to contact us.

    Tapered roller bearings with case hardened parts. The outer ring, inner ring and rollers are made of "bearing grade" surfacing alloy steel for excellent wear life and reliability. Precise control of part heat treatment, dimensions and surface finish further increases bearing reliability.

    Introduction : HL TRB Bearings,the outer and inner raceway and roller of the bearing are designed with convexity. At the same time, the rib structure is optimized to effectively reduce the friction between the bearing parts, improve the transmission efficiency, and make the bearing life and performance better.
