Mainly used in the transmission part of rolling mills and heavy machinery, the tension spring increases the radial force of the sealing lip on the rotating shaft. The GJFL already has an annular groove on its outer diameter, which saves the trouble of machining a lubricating groove on the seal groove. GJFL is the same as previous version of GJFR37.
