ACBB, which is the abbreviation of angular contact ball bearings. With different contact angles, the higher axial load can be well taken care now. TPI standard ball bearings are the perfect solution for high runout accuracy applications such as machine tool main spindles.
Inner and outer rings
Standard ball bearings steel with content of carbon and chromium was selected and hardended to withstand the intense pressure between the rolling element and bearing rings.
Carbonitriding on both inner and outer rings is a basic hardening process for many TPI ball bearings suppliers. Through this special heat treatment, hardness on the raceway surface is increased; which reduces wear accordingly.
Ultra-clean steel is available in some of TPI standard ball bearings' product series now, higher wear-resistance is obtained accordingly.
Rolling element
High precision steel balls ensure TPI's standard ball bearings have the best precision and stability. This also reflects in bearing performance under high speed rotation.
Ceramic balls are an additional option when it comes to severe operating conditions. Extreme high speed rotation, heavy-duty applications and high heat generation while operating are some situations that ceramic balls that can definitely help.
Cage
With the highly engineered arrangement of cages, remarkable characteristics were achieved.
T1 cage, desinged for the requirement of high RPM and stable temperature rise.
T2 cage, desinged for low noise level, however, the temperature rise in high RPM is relatively high.
T3 cage, improvement of T2 cage, it's not only applicable to high RPM operation but also remain low noise level under low RPM.
