Installation method of Stefon and Glyph rings

The Ste seal is to install the O-ring first and then the Ste seal wear ring. First heat the wear ring and then put it on the shaft and then cool it. When installing the wear ring, first press the wear ring inward in the diameter direction. One point. Then install the wear-resistant ring into the groove, and then smooth out the deformation. When placing the shaft, be sure to observe whether the shaft is completely inserted into the wear ring. At the same time, be careful not to block the shaft with the guide belt, otherwise the guide belt may be squeezed out of the groove and crush the seal.

The Glyph ring is the seal of the oil cylinder. Generally, the O-ring is installed first and then the wear-resistant ring of the Glyph ring is installed. For small sizes, the direct installation method is generally used. First, heat it with oil. The oil temperature should not be too high. When the wear-resistant ring is soft, put it on the shaft and then cool it. Large-sized grating rings should use a tapered sleeve, gradually pushing from the small end of the sleeve to the large end, and finally into the groove.

In order to avoid damaging the sealing lip and causing leakage before it is officially put into use, special care must be taken during installation.

1. The sharp edges must be deburred and rounded, and must be chamfered according to the specific requirements of the installation.  

2. Threads, guide ring grooves, etc. should be covered because the seal cannot be pushed through grooves, drilled holes, and rough surfaces.

3. Dust, dirt, debris and other foreign matter must be carefully removed.

4. The cylinder barrel, piston, piston rod and seals should be coated with oil and grease before installation, and consideration should be given to matching the sealing medium.

5. In heated oil or hot water (about 80℃-120℃), the seal is easily expanded and restored to its original shape.

6. The tools used during installation must be made of soft materials (such as polyamide) and have no sharp edges.
