Low-Friction TM-Seal for Transmission Bearings

NSK_TM-Seal_compared_874x555.indd

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.
