What are the types of hydraulic cylinder piston rod wipers?

There are various types of hydraulic cylinder piston rod wipers, and the following are the common classifications:

According to the structural form

Rectangular dust ring: simple structure, good sealing effect, suitable for general working environment.

Chamfered dust ring: It has a certain chamfer design, which can better adapt to the movement of the piston rod and reduce friction.

J-shaped dust ring: The shape is J-shaped, which has a good dust scraping effect and can effectively prevent impurities from entering.

Triangular Dust Ring: Through the triangular structure design, the sealing performance and wear resistance are enhanced.

According to the presence or absence of skeleton

Skeletonless wiper ring: There is no skeleton support, usually made of elastic rubber material, suitable for light and medium load working environments.

Skeleton Dust Ring: A skeleton with metal or other materials that enhances the strength and stability of the dust ring, making it suitable for heavy loads and harsh working conditions.

According to whether it is combined or not

Single-type wiper: made of a single material, simple structure, low cost, suitable for general dust protection needs.

Combined Dust Ring: It is made of a combination of various materials, such as polytetrafluoroethylene (PTFE) and rubber, which has better wear resistance and sealing performance and is suitable for special working environments such as high speed and high temperature.

It is divided by the installation method

Snap-in wiper ring: Installed by snapping into the groove of the end cover of the hydraulic cylinder, the structure is relatively simple, easy to install, and suitable for less harsh environmental conditions.

Press-in wipers: Pressed in the end cap of the hydraulic cylinder, usually wrapped with a layer of metal over the polyurethane material to increase strength, suitable for harsh, heavy-duty conditions.
