Ball Bearings
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Permanently Lubricated Ball Bearings
A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.
Sealed bearings have even better resistance to dust and contaminants than open bearings.

Stainless Steel Ball Bearings
Bearings are 440C stainless steel for good corrosion resistance.
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.
