Rotary Glyd Ring

Size: Standard, or custom made

Material: Copper modified PTFE + NBR, FKM, as you need

What is the rotary glyd ring

The rotary glyd ring is composed of a rubber O-ring and a PTFE ring. In the combination, the O-ring is a force applying element as an elastic element, and the grid ring is a double acting seal. Low friction, no creeping, small starting force, high pressure resistance. According to the use position, it can be divided into hole glyd ring and shaft glyd ring

Advantages of the glyd ring

1) Excellent static sealing performance.

2) A large extrusion gap can be allowed.

3) The friction is small, the friction generates less heat, and there is no creeping phenomenon.

4) The groove structure is simple and can be made into an integrated piston. The installation groove conforms to the international standard ISO7425/2.

5) Good wear resistance and long service life,

6) The mating surface will not adhere during a long period of inactivity or storage.

7) Suitable for most hydraulic oils and most modern hardware materials.

8) Excellent pressure resistance

Matters needing attention in the design of rotary glyd ring

1) Design requirements for glyd ring groove

Reasonable seal ring groove design is a necessary prerequisite for the seal ring to play its advantages. Therefore, it is necessary to refer to the corresponding standards and specifications or the manual of Guangzhou Family for reasonable design of the groove. Here, it is necessary to remind that the size of the radial clearance will affect the sealing pressure. The shaft hole size and the cross section size of the glyd ring with different sizes and specifications may also affect the selection of the radial clearance, which requires special attention

2) Lead in angle design

In consideration of the later assembly of the glyd ring, the piston rod and the hydraulic red cylinder shall be designed with corresponding guide chamfers, so as to facilitate the assembly of the seal ring and not easily cause scratch or damage to the seal ring.

3) Roughness requirements

The reliability and service life of the seal ring largely depend on the quality and surface roughness of the sealing mating surface. Scratches and scratches will not only affect the sealing performance, but also increase the wear of the seal, causing premature seal failure

In addition to the requirements for Ra and Rz of the sealing mating surface, in order to make the seal more durable, the bearing length ratio Rmr (d) of the contour of the mating surface should be controlled. Generally, Rmr (=70%) is required.

Installation requirements for rotary glyd ring

1) If the chamfer is not introduced into the piston rod, a mounting sleeve is required.

2) Deburr and chamfer, and cover the thread end of the bolt to prevent scratching the seal.

3) All workpieces shall be cleaned and free of ash, debris and other external particles.

4) It is better to apply grease or oil to the sealing element during installation, so as to make the installation easier and more convenient. However, it is necessary to ensure the compatibility between sealing materials and these greases. Lubricants containing solid additives are not allowed to be used.

5) The installation tool used must be free from sharp edges.
