A Unitized Pinion Seal for Automotive Applications 890657
A new unitized pinion seal has been developed for use in automotive pinion applications, particularly where the design of the differential can accommodate a yoke-installed unitized seal. The paper reviews a number of existing pinion seal designs and discusses the philosophy behind the new unitized design. The test results presented demonstrate the improved performance of the new unitized design over the conventional non-unitized multi-lip radial lip design commonly used in pinion applications.
