Piston combination seal Two-way sealing ring and other combined piston seals

A combination seal is a combination of two-way acting piston seals. Combined seals suitable for installation in closed grooves.
The oil seal is a double-acting piston seal consisting of three parts: an elastomer, two support rings, and two guide rings. In the middle a sealing element that really plays the role of sealing; A retaining ring and a wear ring are placed on each side. The retaining ring prevents the seal from being squeezed out into the gap; The sealing ring in the middle is a toothed sealing ring, which can play a good sealing role when stationary and moving. The wear ring guides the piston in the cylinder and bears radial forces.

Combined seal ring is a bidirectional acting piston seal ring of this combination. Combination seal ring suitable for installation in closed ditch. The sealing ring is composed of an elastic rubber ring, two additional stop rings and two wear rings. A sealing element in the middle that really plays a sealing role; A retainer and a wear ring are placed on each side. The retaining ring prevents the sealing ring from being extruded into the gap; The sealing ring in the middle is toothed sealing ring, which can play a good sealing role in static and motion. The purpose of the wear ring is to guide the piston in the cylinder block and
