GSZ5
The GSZ5 dust seal (wiper seal)is a type of double-lip dust-proof ring that consists of a wearing ring with sealing and dust-proof cutting edges, along with an O-ring that acts as a pre-tightening element. It is specifically designed for use in challenging environments characterized by severe dust, intense cold, and high-frequency reciprocating motion. The GSZ5 dust seal finds its primary application in hydraulic and pneumatic devices, equipment used in the chemical and food industries. Its main function is to provide effective sealing and prevent the ingress of dust and contaminants, ensuring the reliable operation and longevity of the systems it is employed in.
