High speedball bearings, with smaller rolling elements, HS bearings are able to withstand higher rotating speed than the standard design. Inner and outer rings Standard bearing steel with a content of carbon and chromium was selected and hardened to withstand the intense pressure between the rolling elements and bearing rings. Carbonitriding on both inner and outer rings is a basic hardening process for TPI high speed ball bearings. 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 ball bearings manufacturers’ product series now, higher wear-resistance is obtained accordingly. Rolling element High precision steel balls ensure TPI’s high speed ball bearings have the best precision and stability. This also reflects in bearing performance under high speed rotation. A ceramic ball is 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. Seal The non-contact seal provides general protection for high speed ball bearings. It cannot prevent liquid contamination from getting into the high speed ball bearings. Torque and limiting speeds are the same as the open type.
