Trelleborg Sealing Solutions has just unveiled its newest rotary seal, the Turcon Roto Glyd Ring V. It is a double-acting rotary seal intended for double-acting pressure applications within severe working conditions that require extended rotary service.
The seal has been specifically engineered for machinery where a high pressure-velocity value is required. This allows equipment to run at the highest possible speeds in extreme pressures.
Rigorous tests have been carried out on the Turcon Roto Glyd Ring V, and reveal that it runs with low frictional torque at all pressures from 0.5 MPa and above with low sensitivity to pressure increases from 0.5 to 20 MPa. It also has a built-in valve function, with valve ports connecting to both sides of the Turcon ring profile to the lubricating groove in the centre. An elastomer ring is installed in the lubricating groove to prevent static leakage through the ports.
Rotary seals are used to seal rotary elements such as a shaft or rotating bore. They are most often found in components with oscillating or rotating parts to help keep lubrication fluids in while preventing mud and water from getting in.
