Oil seals work by creating a tight seal around the rotating shaft. This prevents oil and other fluids from escaping while allowing the shaft to rotate smoothly. The seal is usually made up of a lip that fits snugly against the shaft, preventing any leaks from occurring. Some oil seals also have additional features, such as springs or gaskets, to provide extra support and ensure a secure fit.

One of the primary roles of bollards with reflectors is to enhance safety for both pedestrians and drivers. Reflective bollards are designed to be easily visible at night and in low-light conditions. This visibility is crucial, particularly in areas where there may be pedestrian traffic close to vehicles, such as parking lots, sidewalks, and street corners. The reflective surfaces help to delineate boundaries, guiding pedestrians away from potential hazards and ensuring that vehicles are aware of restricted zones. This is especially important in busy urban areas where the risk of accidents can be higher.
