Rotary Seal Ring Rod

ERR Rotary Rod seals are bi-directional, elastomer energized seals for low to medium speed rotary or oscillating applications. Advantages include long wear life, low friction, and simple groove design. Standard ERR seals are etched and coated with a friction promoter at the O-Ring/Seal mating surface. The ERR profile will retrofit non-Eclipse seals designed for similar hardware.
