The Oil Seal 35x50x7 NBR TC is a TC rotary shaft seal sized 35x50x7 mm (ID × OD × width). It keeps oil inside and dirt outside on a 35 mm shaft seated in a 50 mm bore — a size common in AC motors, worm gearboxes, gear pumps and harvest machinery.

About the TC profile
Three features define the TC type: the rubber outer case that fills small bore imperfections, the garter-spring-loaded lip that maintains contact under runout, and the auxiliary lip that acts as a dirt barrier.
Why NBR for this seal
Made of NBR (acrylonitrile-butadiene rubber), the seal tolerates the mineral oils and lithium greases that lubricate most machinery. Standard practice: keep NBR away from brake fluid, and store unused seals in their bag, out of sunlight.
It is normal for a shaft to measure a few tenths of a millimetre smaller than nominal; the sealing lip is engineered to take up that difference.
