Hydraulic seals, also called hydraulic cylinder seals or shaft seals, are parts used to keep fluids from escaping from cylinders, at the same time preventing contaminants from entering into cylinders. They are critical parts in many types of machinery since they help create a method for fluid power to be converted into linear motion. These seals need to be designed and produced to withstand high p...

PTFE (Polytetrafluoroethylene) material is widely used in hydraulic and pneumatic seals. PTFE gets high melting point in excess of 300℃, has good resistance to ageing, as well as low coefficient of friction. PTFE seals are used to enhance friction capabilities, withstand high pressure applications, and extend seal life in applications outside the parameters of elastomeric seal use. We offer a rang...

Piston seals for hydraulic cylinders are quite similar to rod seals, but they are attached to a piston that seals a bore or cylinder housing. These seals are specifically designed to prevent pressurized fluid from leaking down in between the piston and the bore, while the piston itself is pushed down the cylinder bore. The high-quality hydraulic piston seals from JST will keep the pistons in your ...

Spgo seal, also known as glyd ring, is a low friction piston seal, which improves the perfect combination of sealing performance and service life by optimizing contact pressure and reducing the heat generated by friction. The D-section of this seal combines two special groove designs to maintain sufficient lubricating oil film between the seal and the contact surface, which can ensure sufficient f...

Hydraulic cylinders are used to perform work in a variety of different situations and applications on a daily basis. In order to contain pressurized fluid and maintain its movement in the hydraulic cylinder system, two basic types of complex configurations of high-performance seals are required: static seals and dynamic seals (supported by guide rings). There are certain types of seals in each cat...

The processing technology of turning seals is different from that of traditional molded seals. The raw materials for turning hydraulic seals are blank barrels formed by high-pressure extrusion of raw materials after heating and melting, and then the hydraulic seals are turned by special turning CNC seal processing equipment that programs various seal data through software. Turning hydraulic seals ...
