The Oil Seal 26x50x7 NBR TC (26x50x7 mm) renews the sealing on a 26 mm shaft where grease or oil must stay in and grit must stay out — a typical fitment in AC motors, worm gearboxes, gear pumps and harvest machinery.

Inside the TC double-lip design
As a TC-pattern seal it seals in two stages: a primary spring-loaded lip holds the oil film on the shaft, while a second lip fends off dust and water spray; the rubber-covered case keeps the whole unit anchored in the bore.
NBR nitrile rubber at a glance
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.
Measuring your shaft a few tenths under the nominal figure is expected; the spring-loaded lip is built to seal with that small interference.
