Bearings are critical components of any machinery, and they are particularly vulnerable to damage from dust and other contaminants. By using a hub dust seal, you can help to extend the lifespan of your bearings and reduce the need for costly repairs or replacements.

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.

The thermometer that’s built into the lid of your charcoal grill will give you a good basic idea of the temperature inside. Backyard cookout staples like burgers and chicken typically cook best on a charcoal grill from around 375º to 450º. Seared steaks need a higher heat, from 500º to 650º. At these heat levels, food takes only a few minutes to cook and you should be watching the grill like a burger-loving hawk.
