NAK 30x40x7mm Metal Cased FKM Rubber Single Lip Rotary Shaft Oil Seal with Stainless Spring SB - Allow 7-10 Days

NAK SB FKM 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 FKM 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: High-temperature range, Chemical resistance, Higher wear resistance, Lower drag coefficient.
