DESIGN
In some sealing applications, the use of the standard design 76.90H / 76.97H is more complicated because of functional, construction or production-related reasons. This is the case, when the seal type 76.90H / 76.97H is installed into cylindrical bores.
The 76.91 adapter rings are an exceptional choice when a strong abrasive environment results in significant retaining lip wear on the housing contour.
The 76.91 style rings eliminate the need to re-machine the housing, saving time and costs during scheduled maintenance activities.
The Adapter Ring, which is available in possible forms A and B, consists of deep-drawn sheet rings, which are encased in an oil-resistant elastomer material. The static sealing and transmission of torque is guaranteed by an outer wave-profile of elastomer, which also protects from corrosion.
