Radial shaft seal for general industrial applications
Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. The seals have an outer covering of steel or elastomer, designed to fit the housing bore. The sealing lip is made of elastomer or thermoplastic for best sealing against the rotating shaft. A garter spring in the seal optimizes the sealing against the shaft.

Small diameter seals
I use a lot of small diameter inch dimension seals for the repair of older chainsaws. MRO is a great resource for many seals with very competitive prices and free shipping for larger orders. I will continue to use MRO whenever I can.
