Hebei Hankai 70x90x10 oil seal
In addition to protecting the bearings from external contaminants, hub dust seals also help to retain the lubricant that is essential for proper functioning
. As dust and dirt particles infiltrate the hub, they can mix with the lubricant and form a gritty paste that can accelerate wear on the bearings. By keeping the hub sealed tight, the dust seal ensures that the lubricant stays clean and free from contamination, thus extending the life of the bearings.hub dust seal

One of the primary concerns surrounding exposure to welding fumes is the development of respiratory diseases. Workers exposed to high levels of poussière de soudure are at an increased risk of pulmonary issues, such as asthma, chronic bronchitis, and even more severe conditions like pneumoconiosis. The fine particles can penetrate deep into the lungs, triggering inflammatory responses and leading to long-term health complications. Studies have shown that welders are increasingly reporting respiratory symptoms, underscoring the necessity for effective fume control measures in the workplace.
The technology behind portable extractors is designed to capture harmful fumes at the source. Equipped with powerful suction systems and specialized filters, these machines can effectively remove smoke, fumes, and particulate matter from the air, significantly improving air quality in the welding area. Many models utilize HEPA filters to ensure that even the smallest particles are trapped, thus providing a safer breathing environment for operators.
