NAK 1.25x1.875x0.313 inch Metal Cased Nitrile Rubber Single Lip Rotary Shaft Oil Seal with Garter Spring SB - Allow 7-10 Days

NAK SB Nitrile Oil Seals: Oil seals are used in a variety of different applications in which a rotating shaft is lubricated by oil or grease. They are engineered to facilitate the smooth operation of your equipment, serving as a barrier to prevent the leakage of oils and greases while also keeping foreign substances from entering. SB type seals (Also commonly called R4 seals) are commonly used oil seals, particularly in larger shaft sizes or when a smaller shaft requires extra strength. This is due to the metal-cased outside diameter which has a very stable construction and offers a better-protected sealing member in comparison to the open-backed style. The SB features a single-sealing nitrile rubber lip on the inside diameter. The SB types feature a garter spring which allows some give to prevent a build-up of friction. (Seals under 5mm width may not always feature a spring.)
Benefits: Excellent wear resistance, good running properties, high resistance to chemicals and petroleum-based fuels including petrol, diesel and LPG.
