Applications of Internal Circlips The operation method of internal circlips is simple, the structure is simple and reliable, and the cost is low. It is widely used in aviation, shipbuilding, automobile manufacturing, electrical appliances, chemical machinery, railway, construction engineering, mechanical and electrical equipment installation, instruments and meters, mechanical equipment, medical treatment, chassis cabinet, furniture, electronics and other industries.
Installation Methods of Internal Circlips 1, The installation must use the circlip pliers, insert the pliers mouth into the clamp hole of the stop ring, and clamp the stop ring, in order to put it into the pre-processed circular hole groove;
2, Install the hole with the external circlips on the tooling, and then through a hole to reduce the stop ring to the size of the installation hole and push the steel wire stop ring into the installation hole.
Advantages of Internal Circlips High tensile, the hardness and elasticity of qualified; The surface is flat, with standard pliers holes ; No burrs in the corner. Materials we can use on Internal Circlips Related Products Related News
