Gleycircle and Steffen differ significantly in several ways:
1. Composition and structure:
The Glay ring consists of a high-wear PTFE composite with a rectangular section, slip ring seal and an O-shaped rubber seal as a preload element. It has pressure guide grooves on both sides to accommodate rapid pressure changes.
The Sterseal is composed of a step-shaped polytetrafluoroethylene slip ring seal and an O-shaped rubber seal. The cross section of the Steffen slider is in a stepped shape on the side of the seal (relative moving side).
2. Function and function:
The Gray ring is bidirectional sealing, suitable for sealing between the hydraulic cylinder hole and the piston, for the design of pressure on both sides of the piston. It has very high pressure stability, good thermal conductivity and extrusion resistance, high wear resistance, low friction, no hydraulic crawling phenomenon.
The sterseal is one-way sealed and is divided into piston and piston rod. It can only seal the pressure in one direction, and is especially suitable for the piston rod seal of the sealing system. The sealing effect of Sterseal is generally better than that of Grey-ring seal.
3. Application Scenario:
Both Grey Ring and Sterseal are suitable for hydraulic equipment, such as presses, excavators, metallurgical equipment, loading and cutting machines, machinery manufacturing and other places. The Gray ring can be applied to the larger diameter of the hydraulic cylinder 2500mm, and the Sterseal is applied to all piston cylinders and piston rods within the larger diameter of 1330mm.
In general, the Glei ring and the ster seal have their own characteristics in composition, function and application, and the choice of seals depends on the specific application scenario and needs
