The bearing dust seal is a hook-shaped crimping layout; compared with the existing skills, it has the following advantages:
The sealing function is good; the sealing strength is high; the original hook-shaped curling layout of the skeleton can increase the elasticity of the sealing ring; the maximum limit compensates for the influence of the tooth size deviation; it not only depends on the elasticity of the sealing elastic body; The elasticity and strength effect; the capping rate is improved; and the machine can be pressed; it can be pressed.
The life of a sealed bearing is largely determined by its sealing function; the current bearing seal is a hemmed skeleton; it is usually pressed by hand; the primary drawback is: poor elastic strength; poor installation function; poor sealing function.

Product introduction
HHCMS-220 Carbon Molecular Sieve
The HHCMS-220 is a new nonpolar adsorbent designed to extract nitrogen-rich gas from air. It is suitable for separating nitrogen from air. It has a high adsorption capacity for oxygen and can separate nitrogen from air.
The most notable features of the carbon molecular sieve are high gas-producing efficiency and low energy consumption, especially for the preparation of nitrogen with a purity of less than 99.5% to 99.9%.

Pay attention to
1. The nitrogen production equipment can reduce the adsorption temperature to better show its excellent nitrogen production performance under conditions;
2. Pay attention to low temperature drying and seal preservation during storage;
