The ST-XLFT was developed for hard environments, particularly longwall mining. These wipers include a dust lip to prevent contaminates from entering through the groove. They also have a ribbed inside diameter for low friction operation and to prevent pressure traps between the wiper and rod seal.
93A Durometer | Urethane Material | 6 in Nominal Inner Diameter
Features
- Include a dust lip to prevent contaminates from entering through the groove
- Ribbed inside diameter for low friction operation
- Prevent pressure traps between the wiper and rod seal
A wide range of ST wipers are now offered in the slotted heel design. The slots in the heel allow excess hydraulic fluid to bypass the wiper, preventing wiper blowout.
90A Durometer | Urethane Material | 1 1/8 in Nominal Inner Diameter
Features
- Slotted heel design
- Slots in the heel allow excess hydraulic fluid to bypass the wiper
Style ST wiper rings are precision molded from 90A durometer urethane. Flexible enough to easily snap into a groove yet tough enough to handle difficult rod wiping applications. “V” tagged wipers are constructed of fluorocarbon.
90A Durometer | Urethane Material | 1 7/8 in Nominal Inner Diameter
Features
- Flexible enough to snap into a groove
- Wipers are constructed of fluorocarbon
A wide range of ST wipers are now offered in the slotted heel design. The slots in the heel allow excess hydraulic fluid to bypass the wiper, preventing wiper blowout.
90A Durometer | Urethane Material | 2 in Nominal Inner Diameter
Features
- Slotted heel design
- Slots in the heel allow excess hydraulic fluid to bypass the wiper
The style MW38 wiper is made from tough abrasion resistant polyester based material for difficult conditions found in mining and earth moving applications. It incorporates a sealing lip on the outside diameter to prevent moisture entering the groove.
The Hallite 38 single-lipped polyester wiper/scraper is designed to fit metric housings including those of ISO 6195A. Suitable for heavy duty applications. The proportions of the wiping lip ensure that contact is maintained with the surface of the rod to remove heavily deposited containments such as mud and ice.
55D Durometer | Polyester Material | 180 MM Inner Diameter | Wiper
Features
- Crush lip design provides effective seal on housing
- Ribs relieve pressure and improve stability
- Effective scraping lip to scrape off heavily deposited containments including ice
Wipers are installed in hydraulic cylinders to prevent dirt, dust, and moisture from entering the cylinder as they retract back into the system. A hydraulic wiper prevents contamination that could damage wear rings, seals, and other cylinder components.
90A Durometer | Urethane Material | 3/4 in Nominal Inner Diameter
Features
- Installed in hydraulic cylinders to prevent dirt, dust, and moistures
- Hydraulic wiper prevents contamination that could damage wear rings, seals, and other cylinder components
Style AN-M2 scrapers conform to MS28776-M2 sizes and are manufactured in brass. The scrapers are suitable for extreme environments with aggressive contaminants. The unique spring-loaded construction and ductile material result in close rod contact even when coping with rod ovality and helix grinding patterns.
Brass Material | 2 1/2 in Nominal Inner Diameter
Features
- Scrapers are suitable for extreme environments with aggressive contaminants
- Unique spring-loaded construction
- Manufactured in brass
