441 Series: Rotary Seal
The 441 Series Rotary Seal is a popular seal used in low-to-moderate speed applications that require maximum reliability and long service life.
441 Series
The 441 Series Rotary Seal is a popular seal used in low to moderate speed applications that require maximum reliability and long service life. The unique encapsulated spring ensures that the spring remains in place during a blind installation. The main body is strong yet flexible for ease of installation and stability within the groove. The lip force is optimized for the full range of sizes by varying design of the internal spring, allowing low friction and minimal wear.
