Features: 1.The AS-R12 seal contains secondary seal——o ring,and the face materials and elastomers can be changeable according to different application requirements. 2.The seals depend on the direction of the rotation. One can judge the direction of the rotation from the drive end of the shaft.(The clockwise rotating shaft asks for the right handed spring and anti-clockwise rotating shaft asks for left handed spring.) 3.The conical helical springs transmits the torque and can be fitted easily by pushing on the shaft and twisting as the spring winding. So, the spring diameter can be enlarged easily to make easy installation.
