Rotary Shaft Seals FAQ
Q: What is the expected service life of rotary shaft seals?
A: The service life depends on operating conditions, but our premium rotary shaft seals typically last 3-5 years in normal conditions. Extreme temperatures, aggressive chemicals, or abrasive environments may reduce lifespan.
Q: How do I select the right rotary shaft seal for my application?
A: Consider these factors: shaft diameter, operating temperature range, media being sealed (oil, water, chemicals), pressure requirements, and rotational speed. Our technical team can assist with proper selection.
