This design guide provides data on a widely used type of seal: the shaft seal. As you review the contents, please keep in mind that the many materials and designs featured in this guide are just part of the wide variety of sealing solutions offered by R.L. Hudson & Company.

Though we have tooling for over 20,000 standard shaft seal sizes, we recommend that each seal be designed for its specific application. For example, a gearbox seal designed for low speed and low temperature use will not necessarily work in a gasoline engine application. To determine the best seal for your project, consider the following factors: the materials (both elastomeric and metallic) to be used for the seal; the type of seal application; the operating conditions; the seal dimensions; and the design of the shaft and housing bore. Follow the steps below to design your shaft seal.

Before you begin, however, you may find it helpful to quickly review a few of the basics. A Shaft Seal Primer gives a brief overview of sealing concepts. Back to Basics takes a look at why elastomeric materials make good seals.
