We have CNC machines and cooperate with universities and research institutions and have rubber material research and development team.
We established long-term cooperative relations of technology talents with Qingdao University of Science & Technology, Hebei University of Technology, northwest Rubber Institute, each batch on employee training, improve the staff technical level and cultural structure, creating a number of business elites. It lays a solid foundation for the healthy development of the company.
1. Standard:
VD rubber seal JB / T 6994-93
2. Features:
Rotating end face sealed with pure rubber to prevent the outside of dust, powder, water and their mixtures and grease into the bearing or sealing system. Can be used in most bearings, and can be used as a secondary seal for the main seal easy to failure in harsh environments.
3. Materials:
Under normal circumstances the use of nitrile rubber NBR; in the use of temperature higher than 100 ºC, or extreme chemical resistance of the case, the choice of fluorine rubber FKM.
4. performance:
* Easy to install, can be normal stretching and rely on the elasticity of the rubber itself to tightly wrapped in the rotation axis;
* Lip contact pressure is small, and the contact pressure decreases with increasing linear velocity, good wear resistance;
* Allows a certain degree of shaft eccentricity;
* Effective prevention of dust, powder, water, grease and other intrusion.
We can design and manufacture various rubber parts, custom-made is welcome
