Design

Ball screw series, is designed to maximize smaller ball numbers with thicker I/R & O/R and 60 degree contact angle. This design allows BS series has greater axial rigidity than any other TPI angular contact bearing series.
HBS is designed to accommodate heavy load application, such as plastic injection molding machine. Compare to BS series, HBS provide relative higher load rating and stiffness.

Inner and outer rings
  • Carbonitriding on both inner and outer rings is a basic hardening process for many TPI bearings. Through this special heat treament, hardness on the raceway surface is increased; which reduce wear accordingly.

Rolling element
  • High precision steel balls ensure TPI's angular contact ball bearings have the best precision and stability. This also reflects in bearing performance under high speed rotation.

Cage

With the highly engineered arrangement of cages, remarkable characteristics were achieved.

  • T2 cage, desinged for low noise level, however, the temperature rise in high RPM is relatively high.

Contact seal
Seal
  • Contact seal, prevent dust and liquid contamination from getting into the bearings. However, the torque will be higher and the limiting speeds will be lower under such application.
  • Non-contact seal, provide a general protection for the bearings. It cannot prevent liquid contamination from getting into the bearings. Torque and limiting speeds are same as the open type.

Grease

TPI cooperates with the best grease manufacturers in the world which allows us to suggest and apply the best lubricating selection for our customer.

proimages/pro/angular_contact_ball_bearing/standard/life.png
Life

Bearing life is usually expressed as the number of hours an individual bearing will operate before material fatigue develops on either the raceways or the rolling element. The usual life rating for industrial applications is called “L10” life. The L10 life is the number of hours which that 90% of bearings will survive; or, conversely, 10% of bearings will have failed in the L10 number of service hours.

Preload / Rigidity

System rigidity, one of the main factors of productivity and accuracy when it comes to machine tools and other precision applications. By preloading the bearings, it becomes extremely rigid and the magnitude of elastic deformation becomes neglectable.

proimages/pro/angular_contact_ball_bearing/standard/arrangement.png
Arrangement

Angular contact ball bearings in duplex arrangements vary in combintations of two, three or four, in accordance to user's required specifications.
Back-to-back duplex (DB) arrangement and face-to-face duplex (DF) arrangement can both sustain radial and axial loads in both directions. The wider distance between the effective load centers of the DB arrangement allows larger moment loads to be handled.

Designation

The designation indicates the form, size, precision, internal structure, etc. of the bearing, and it's shown as below:
