Wiper Z-07 44,45x57,15x6,35 PU+Stal

The Z-07 type wiper ring is used as a protection against the ingress of dirt, mud, and moisture into the working parts of hydraulic cylinder components.

It is most commonly mounted on pins or trunnions in the cylinder eyes, where it prevents dirt from entering the lubricated space.

Construction and operation:

The wiper is made of highly abrasion-resistant polyurethane (PU) and is seated in a steel casing that ensures rigidity and secure retention in the socket. The Z-07 design allows the wiper to be driven into the housing, ensuring stable mounting even under severe dust and vibration conditions. During operation, it effectively "wipes" contaminants from the moving surface, protecting the bushings and internal lubricant from degradation.

Application:

• pins and hinges of hydraulic cylinders,
• cylinder eyes in construction and agricultural machinery,
• mechanisms lubricated with grease, exposed to mud and dust.

Materials:

• working part: polyurethane (PU),
• casing: steel,

Advantages:

• high resistance to abrasion and ageing,
• strong, secure seating in the socket,
• effective protection of the lubricant and working surfaces,
• easy replacement during cylinder servicing.
