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
Nitrile rubber (NBR) is the workhorse of oil sealing: fully compatible with mineral oils, lubricating greases and common hydraulic fluids — the media found in most gearboxes and motors. Avoid contact with brake fluid, and keep spares shaded from sunlight.
Should the shaft read slightly below the listed size — typically a few tenths of a millimetre — no concern: the lip’s interference fit accounts for it.
