Stein’s bushing seals are the perfect choice for high-pressure gas and liquid applications. Each bushing seal is custom designed to fit the application and is often combined with our other seals to create sealing systems that meet the most stringent operating requirements. The bushing seal is a sleeve that forms a small clearance about a shaft where leakage is limited by flow resistance between the clearance and the bushing. Bushings can be designed in either a fixed or floating sleeve configuration depending on the operating clearance requirements, shaft movement, vibration or misalignment. For machinery such as steam turbines, segmented bushings allow easy maintenance access to the shaft.

Typical applications include aircraft engine main shaft seals, compressors, pumps, and high-speed processing equipment. Configurations include either a floating or fixed design depending on the tolerances of the specific applications

• Floating bushings move radially, but are captured axially in the housing with spring loading, to better tolerate any shaft movement
• Available in a wide variety of materials suitable to each application: alloy, steels, 300/400 series stainless steel, Inconels, Hastelloy, ceramics and carbon graphite
