Ball screw bearings series, shorten as BS bearings, is designed to maximize smaller ball numbers with thicker I/R & O/R and 60 degree contact angles. This design allows BS bearings to have greater axial rigidity than any other TPI angular contact bearing series, like standard ball bearings.
HBS bearing is designed to accommodate heavy load applications, such as plastic injection molding machines. Compare to BS bearings series, HBS bearing provides relatively higher load rating and stiffness.
Inner and outer rings
Carbonitriding on both inner and outer rings is a basic hardening process for TPI BS bearings. Through this special heat treatment, hardness on the raceway surface is increased; which reduces wear accordingly.
Rolling element
High precision steel balls ensure TPI ball bearings suppliers' BS bearings and HBS bearing have the best precision and stability. This also reflects in BS bearings performance under high speed rotation.
Seal
Contact seal, prevent dust and liquid contamination from getting into BS bearings. However, the torque will be higher and the limiting speeds will be lower under such application.
The non-contact seal provides general protection for BS bearings. It cannot prevent liquid contamination from getting into BS bearings. Torque and limiting speeds are the same as the open type.
