V-Seals and ExcludersProduct OfferingCatalog EPS 5350/USAProduct LineThe V-Seals are flexible rubberseals which mount on and rotate withthe shaft against a counterface. Theflexibility of the seal allows for someshaft end play. The seal configurationprotects against contamination and canbe used to supplement the primaryshaft seal in a harsh environment.The DS can be used as a deflectoror an excluder and is manufacturedfrom a dense composite material.The SSW design is similar to theV-Seal, but is manufactured with anon-metallic composite constructionat the ID that is press fit onto the shaftfor heavy duty applications. The SSWwill not lose the press fit on the shaftat higher shaft speeds — allowing formore consistent lip contact.ProfilesTable 12-1.

The design is pressfit onto the shaft. DS isknown as a deflector seal.SSW is designed forapplications for externalwashdowns or severe dustyenvironments. The seal ridesagainst the face of thehousing to keepcontamination from theprimary seals.Used internally ongearboxes or otherindustrial equipmentwith internal splash.Also used asexternal slinger.Electric motors,mining or washdownapplications, rollingmills.12-912-9121203/28/0612-4 Parker Hannifin CorporationEPS DivisionToll Free: (800) 233-3900www.parkerseals.com
