Experience the power of PU5 Wipers - wipers that effectively ward off dirt thanks to an additional static sealing lip and bearing segments. The sealing edge of the wiper lip is slightly rounded for optimal performance.
The benefits of PU5 Wipers are remarkable. These single-acting wipers can also be used in standardized housings according to ISO 6195 Type A. The added static sealing lip prevents the ingress of dirt and splashing water. The wiper lip with a slightly rounded sealing edge reliably wipes away dirt and leaves a residual oil film on the retraction rod. This improves friction behavior and lifespan. The support on the wiper heel prevents twisting in the groove and pressure buildup between the wiper and seal.
PU5 Wipers find their application in various sectors, including mining, earthmoving equipment, industrial vehicles, loading platforms, agricultural machinery, cranes, presses, injection molding machines, support cylinders, and telescopic cylinders. Careful assembly is a prerequisite for the proper operation of the Merkel Wiper PU 5. Generally, wipers can be quickly and easily adjusted by deforming them into a kidney shape. Refer to the technical manual for detailed instructions. The length and angle of the run-in chamfers must be designed to match the rod seal used for seamless integration.
Choose PU5 Wipers for effective dirt protection and optimize your machinery's performance. With their static sealing lip, rounded sealing edge, and precise assembly, these wipers contribute to smooth equipment operation, even in demanding conditions, while minimizing wear and tear.
