Oil seals can be made from various materials, including rubber, silicone, and polyurethane. The choice of material often depends on the operating conditions such as temperature, pressure, and the type of lubricant being used. For the 50x65x8 oil seal, nitrile rubber (NBR) is commonly utilized due to its excellent oil resistance and durability in a range of temperatures.

One of the primary consequences of operating with a brake drum that is below its minimum thickness is overheating. As the drum wears down, it may not dissipate heat efficiently, which can cause the brakes to overheat. Overheating can lead to brake fade, where the effectiveness of the brakes diminishes significantly, making it harder to stop the vehicle. This can be particularly dangerous in emergency situations where rapid stopping is necessary.
