Gland Piston Seal Manufacturer & Supplier - Coimbatore India
Gland
The cylinder head is fitted with seals to prevent the pressurized oil from leaking past the interface between the rod and the head. This area is called the seal gland. The advantage of a seal gland is easy removal and seal replacement. The seal gland contains a primary seal, a secondary seal/buffer seal, bearing elements, a wiper/scraper, and a static seal. In some cases, especially in small hydraulic cylinders, the rod gland and the bearing elements are made from a single integral machined part.
Piston
Inside the barrel, the piston is the component attached to the rod that bears the force of the hydraulic fluid, allowing it to extend or retract. A piston is often machined with several grooves to allow seals to fit around it and maintain hydraulic pressure inside the barrel. The piston transfers its power to the piston rod and is attached by threads, bolts, or nuts.
