RWS Seal Guard® Metallic Rod Wiper/Scraper

RWS Seal Guard® Metallic Rod Wiper/Scraper

Description

Each Seal-Guard® contains two staggered, wear compensating flexible bronze rings encased in a synthetic rubber cushion. The cushion ring absorbs side loads, and under compression, exerts a steady inward force to keep the conical surfaces of both metal rings in full circular contact with the rod. The knife edges of these specially slotted metal rings effectively lift or shave foreign materials off the surface of the rod.  Seal-Guards® are self-adjusting and create very little friction. They are simple to install. Use of nitrile cushions and bronze wiper/scraper rings permits Seal-Guards® to operate at temperatures ranging from -45°F to +250°F (-43°C to +121°C).
