S34 - SEAL-GUARD® 2 PC BRONZE/NBR WIPER/SCRAPER - INCH

For heavy-duty protection against hard contaminants such as ice, mud or metal spattering, the self-adjusting Seal-Guard® “scraper” is an ideal exclusion ring. Seal-Guard® consists of two knife-like bronze rings and a nitrile cushion ring. To eliminate the clogging and caking of contaminants under the ring, the conically tapered bronze rings act as blades to remove and dispose of foreign matter away from the rod and ring. The notches in the bronze rings provide flexibility, allow for expansion and produce a spring effect resulting in constant contact with the rod, full circle. When compressed, the cushion ring preloads the wiper rings for wiper edge contact with the rod and it absorbs shock and side loads; therefore, its self-adjusting. To install the Seal-Guard® wiper, cut a groove in the gland, install the bronze rings, staggering the notches. Then using a dull tool and a light film of oil, push the cushion ring into the counter bore under the retaining ring. Temperature: -40° to 250°F.
