Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

1. Local Exhaust Ventilation (LEV) This system captures fumes and gases at the source before they can disperse into the work environment. LEV involves the use of hoods positioned close to the welding area, ensuring that contaminants are efficiently collected and filtered. This method is particularly effective for robotic welding cells where the welding operations are concentrated in a specific area.
