NAK 20x28x4mm Metal Cased Lead-in Chamfer FKM Rubber Double Lip Rotary Shaft Oil Seal with Stainless Spring TM - Allow 7-10 Days

NAK TM 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. TM type seals are often used 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 TM type oil seals feature a lead-in chamfer and have an additional inner rubber lining particularly fit for protecting the case from erosive fluid. The TM features a sealing FKM rubber lip on the inside diameter as well as an external dust lip. The TM 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.
