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.

One of the primary reasons antique terracotta roof tiles are sought after is their durability. Unlike modern roofing materials that may succumb to the ravages of time, high-quality terracotta can last for decades, if not centuries. When properly maintained, these tiles resist the elements—standing up to rain, snow, and extreme temperatures without warping or deteriorating. This resilience makes them an enduring choice for those seeking aesthetics without sacrificing functionality.
