In addition to preventing oil leakage, cylinder oil seals also help to prevent contamination. Contaminants such as dirt, dust, and moisture can enter the cylinder and cause damage to the internal components. This can lead to reduced efficiency, increased maintenance costs, and a shorter lifespan for the machinery. By creating a tight seal around the cylinder shaft, oil seals help to keep contaminants out and protect the internal components from damage.

rear hub oil seal. Oil may begin to leak out of the hub, leading to low oil levels and potential damage to the hub components. The hub may also become contaminated with dirt and debris, causing increased wear and potential failure of the bearings and other parts.




In addition to its superior feeding mechanism, a compound feed heavy-duty sewing machine is also equipped with a powerful motor. This allows the machine to sew through multiple layers of fabric, thick materials, and heavy-duty materials with ease. The high-speed motor ensures fast and efficient sewing, making it ideal for large projects or production sewing.
