Electrically Insulated Ball Bearings
Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing. The ceramic balls generate less heat than steel balls, so they require lubrication less frequently. Shields keep out dust and contaminants.

Spherical-Roller Bearings
Two rows of rollers give these bearings dynamic radial load capacities over five times higher than comparably sized tapered-roller bearings. Also known as rock crusher bearings, they handle heavy shock loads and are used for metal milling machinery, mining and oil field equipment, and in paper mills.

Cylindrical Roller Bearings
With cylindrical rollers to distribute load over a large surface area, these bearings are often used to support heavy loads at high speeds in applications such as power generation and metal recycling. A cage prevents the rollers from touching each other, reducing friction for high-speed use. All of these bearings have an inner ring that's flanged on one side, so they only allow heat expansion in one direction. The bearings can be taken apart, so you can install them with precision and quickly dismantle them for maintenance or replacement.
