Scraping dirt, moisture, and debris off a cylinder rod as it retracts, this Raymond wiper seal keeps outside contamination from being dragged past the main seal and into the hydraulic system. Sitting at the outermost point of a rod gland, it clears the rod on every stroke, protecting the rod seal and the fluid from the abrasive grit that causes most premature seal and cylinder wear.
Scraping dirt, moisture, and debris off a cylinder rod as it retracts, a wiper seal keeps outside contamination from being dragged past the main seal and into the hydraulic system, and Raymond fits this one to that duty. A wiper, or scraper, seal sits at the outermost point of a rod gland, where it is the first line of defense for everything sealed behind it.
By clearing the rod on every stroke, it protects the rod seal and the fluid from the abrasive grit that causes most premature seal and cylinder wear. It is a small part guarding much more expensive ones, which is why it earns a place in every seal service.
A wiper hardens, cracks, or loses its edge over time, and once it stops clearing the rod cleanly, contamination reaches the main seal and cylinder wear accelerates. Confirm the rod diameter and the wiper's groove dimensions against the seal being replaced, since a wiper has to match both the rod it rides and the gland it seats in.
