Conical Single Spring Seal

We are popular as a trustworthy Conical Single Spring Seal Manufacturer and Exporter from India. Our Conical Single Spring Seal is made from high quality raw material that ensures excellent durability. The Conical Single Spring Seal is known for its easy to install feature.

Construction & Working :
Our GLOBE STAR Make U3 Series of Conical Single Spring Seals are Single Conical Helical Spring & Unbalanced Seals With 'O' Ring as Secondary Sealing Member. As the Torque Transmission is done by Conical Helical Spring, these Seals are Dependent of the Direction of Rotation. For Easier Fitting the Conical Helical Spring should be pushed on the Shaft with a Twisting Motion in the sense of the Spring Winding. This movement enlarges the diameter of the Spring Enabling Easy Fitment. Direction of Rotation is seen from the Drive end of the Shaft. Clockwise Rotating Spring Shaft Requires Right Handed Spring & Anti-Clockwise Rotating Shaft requires Left-Handed Spring.
