ABSTRACT:
A rubber dirt-excluding and grease-retaining seal for use in machine assemblies such as furrow forming disc assemblies in grain drills, marker disc assemblies and the like comprises a generally cylindrical, accordian-like body formed of interconnected pocket like rings defined by generally radially extending interconnected walls rendering the body axially compressible and extensible. In use, the seal is compressed between a rotary disk like member on a shaft and a stationary hub like member and is useful in excluding dirt from the disc bearing while retaining grease therein.
