If your 38 mm shaft is weeping oil, the Oil Seal 38x75x8 NBR TC — a TC spring-loaded seal at 38x75x8 mm — restores the barrier between the 75 mm housing and the outside world. A staple size for drive motors, planetary gearboxes, irrigation pumps and feed mixers.

Why the TC profile is so widely used
The TC layout brings three protections together: a rubber outer surface that grips the housing bore, a garter-spring lip that tracks slight shaft movement, and a secondary dust lip that blocks grit before it reaches the sealing edge.
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.
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.
