pneumatic wiper seal

20 30 7 oil seal.
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.

Drum brake anchors are typically made from durable materials such as cast iron or heavy-duty steel to withstand the immense forces exerted during braking. Their design is engineered to endure heat generated from friction when brakes are applied. Over time, the heat can cause wear on various components involved in the braking system, but a well-designed anchor helps mitigate some of these effects by maintaining stability and strength.
