These type of seals with single conical helical spring is unbalanced with 'O' Ring as secondary seal. Various seal face material and elastomers can be offered for wide application. As the torque transmission is done by conical helical spring. these seals are dependent of the direction of rotation. Direction of rotation is seen from the drive end of the shaft. Clockwise rotating shaft requires right handed spring and anti-clockwise rotating shaft requires left-handed spring.
For easier fitting and 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.
