KASTAS WIPER SEAL K11
K11 is a single acting scrapper ensuring that foreign particles do not penetrate into the hydraulic cylinders, avoiding wear and damage to all the internal components incuding seals.
| PRODUCT ADVANTAGES |
| Superior scraping effect |
| Simple, easy-construction groove |
| No twisting in the housing |
| Design in a way that the wiping lip contacts with the rod surface to remove heavily deposited mud, ice, etc so that the particles do not enter into the cylinder |
| Outside diameter contacts the housing and has a sealing lip toprevent moisture entering the groove. |
| APPLICATION |
| Especially used in heavy construction machinery that operate in the open feld, telescopic cylinders, cranes, mining equipment and loading platforms. |

SURFACE ROUGHNESS | Ra | Rmax | |
| Sliding Surface | Ød | ≤0.4 μm | ≤3.2 μm |
| Groove Base | ØD | ≤1.6 μm | ≤10 μm |
| Groove Flanks | S1 | ≤3.2 μm | ≤16 μm |
| INSTALLATION |
| Open housing is recommended but closed grooves can be used for wipers bigger than 40 mm inner diameter. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil. |
