Conical Spring Seal (CSO 100 Series)


Quba’s Conical Spring Seal CSO 100 Series is a conical helical spring, unbalanced seal with ‘O’ ring as secondary sealing member. Various seal face & elastomers can be offered for different service applications. As the torque transmission is done by the conical helical spring, these seals are dependent of 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 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, the conical helical spring should be pushed on the shaft with a twisting motion in the sense of spring unwinding. This movement enlarges the diameter of the spring, enabling easy fitment.
