Lipped seal

circularbearing protectionfor gearbox

NSK has developed a low-friction seal for transmission bearings that reduces the seal friction by 50%, in comparison to the old TM-seal design (10% friction reduction on the complete bearing). NSK's fitted bearings with TM-seals are used inside transmissions to inhibit the ingress of gear dust and other contaminants. Condition Description Corrosive Environment Low Friction Industries Automotive Product Features The seal friction was reduced by narrowing the seal lip by 10% and lengthening it by 70%, compared to conventional bearings The seal lip shape was improved based on computer analysis; the new shape improves lip-following and stabilises the contact pressure along the edge. Benefits Seal friction reduced by up to 50% compared to the old TM-seal design and total bearing friction reduction of around 10%. Same durability as the replaced TM-bearings by preventing the ingress of contaminants to the transmission oil in the bearing. The bearing life is improved by 2,5 times in comparison to open bearings.
