Hebei Hankai rotary oil seals
The primary function of axle hub seals is to retain lubrication. Proper lubrication is essential for the smooth operation of moving parts, reducing friction and wear. Without effective sealing, the lubricant can leak out, leading to inadequate lubrication of the gears and bearings, which may cause premature wear and eventual failure of the components.

Expectorants are often a part of the treatment regimen for acute respiratory infections, coughs, and conditions characterized by increased mucus production. Physicians may prescribe them when a patient presents with persistent cough, chest congestion, or difficulty in expectorating phlegm. Additionally, expectorants are sometimes recommended for patients undergoing treatments like bronchoscopy to help clear mucus from the airways.
