The modernized production mode accelerates DMS Seals O Ring Manufacturers production process. The value of the product is reflected in superior quality and outstanding performance. Our O Ring Manufacturers is widely used. The modernized factory of Dms Seals Technology Co.,limited has very large scale and great capacity.

Product Description

Our O Ring Manufacturers has a certain share in the market because of the following characteristics.

1. Performance and use

It is suitable for one-way sealing of reciprocating piston rod or piston, and can also be used for rotating shaft sealing. It has good sealing performance at high, medium and low pressure.

The working pressure can be adapted to a wide range, and the pressure resistance can be enhanced by adding a retaining ring.

The friction coefficient is small, the contact pressure with the mating surface is low, the friction with the mating surface is very small during operation, it can work with or without lubrication, it is wear-resistant and has a long service life.

The working medium of the sealing sleeve has wide adaptability, except for soluble alkali metal, high-temperature fluorine gas and chlorine trifluoride, other chemicals do not react with it.

The wide operating temperature range can be used from -200°C to +250°C.

It can be used in special working conditions such as extremely high speed, extremely low speed, and micro stroke.

Suitable for aviation, military and industrial seal groove sizes, small installation grooves, open or semi-open grooves.

2. Materials

Sealing sleeve: Filled with polytetrafluoroethylene (PTFE). According to different working conditions and sealing requirements, different filling materials and filling processes can be selected, please contact us for details.

Spring: stainless steel 301, 302, 304, 316 or 718, depending on the specific working conditions, the default is 301, please inquire and explain before ordering for special working conditions.

3. Labeling method

FSKR "groove bottom diameter/hole diameter D" × "shaft diameter d" × "groove width L" – "spring material" O

For example, FSKR100×90×7.5-316O means “O-shaped spring hole shaft double-purpose universal plug, the working size is: shaft diameter 90, groove bottom diameter/aperture diameter 100, groove width 7.5, spring material is stainless steel 316.

4. Precautions:

Ⅰ, The installation groove must be open or semi-open, it is recommended to be open.

Ⅱ, If it is a rotary shaft seal, the surface hardness of the shaft should not be less than HRC40.

Ⅲ. When considering the adaptability of the working medium, the adaptability of the sealing sleeve and the spring should be considered.

Ⅳ. It is better to install an anti-fouling ring or a guide ring with anti-fouling effect on the front of the seal (opening direction).

Ⅴ, If the working pressure is greater than 20MPa, the groove width needs to be increased accordingly, and the specific value needs to consider factors such as working temperature and running speed.

Ⅵ, it is ideal for static sealing, if it is used for dynamic sealing, the dynamic axial runout is required to be no more than 0.05mm.
