K842
Design Introduction
Kintowe K842 rod wiper is designed to prevent the ingress of external particles and moisture into the cylinder. The profile has been specially developed for harsh environments, in particular the longwall mining industry.
The special feature is the flap on wiping which covers the gland housing , preventing the water/slurry trap so common with conventional wipers and thus ingress of contamination around the outside of the wiper.The internal ribs on the inside diameter prevent the possibility of pressure trapping between the gland seal and the wiper and ensure correct support and guidance of the wiping lip , even in cases of high eccentricity as can occur between the outer stage gland and the inner cylinder of a roof support leg.
K842 is precision moulded in high performance polyurethane-KINTOWE®01 , the material has excellent compression set characteristics, excellent wear and abrasive resistance, proven compatibility with HFA(95/5) fluids , as used in longwall mining equipment , and with mineral oil.
Advantages
● Compatible with HFA (95/5) high water-based working fluid and mineral oil used in long-arm mining equipment
● Excellent resistance to permanent deformation
