Spno Rolling Mill Bearing Seal Ring Mg

1 Рекомендации по установке 

It is suitable for piston rod sealing, mainly used in medium and high pressure cylinders, and can withstand high working oil pressure.

The friction coefficient is small, which is conducive to the rapid response of the cylinder to the action, and can be applied to the servo cylinder.

The adaptability of the working medium and the working temperature range can be changed by changing the material of the O-ring.

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

The mounting groove is relatively small. The seal is easy to install and generally requires no special tools.

Comply with GB/T 15242.1-94 and GB/T 15242.3-94 standards.

Strong pressure bearing capacity and larger installation clearance than ordinary seals, which can reduce the matching accuracy of corresponding metal parts and reduce manufacturing costs.

2. Материалы

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

O-ring: nitrile rubber NBR, fluororubber FKM. The material of the O-ring is determined according to the temperature and working medium of the working condition, if you are not sure, please contact us. If you need to match fluorine rubber (FKM) O-ring, you need to explain before ordering.

3. Precautions:

Ⅰ. If other parameters of the matched O-ring are qualified, the diameter of the ring is 1-2% larger than the value listed in the sample, which will not affect the use.

Ⅱ. When installing, you can bend the sealing ring into a heart shape and put it into the groove, but there must be no creases. In the two cases shown in the figure below, A is allowed and B is prohibited.
