Tapered-Roller Bearings

Found anywhere from machine tool spindles to conveyor rollers, these bearings have a two-piece design that allows for adjustment.

Zinc-Plated Steel Ring—Zinc-plated steel ring bearings provide better corrosion resistance than steel bearings.

Extreme-Load Tapered-Roller Thrust Bearings

With thick, tapered rollers, these thrust bearings are the strongest we offer. The rollers spin inside a raceway instead of a cage, so there’s room for more rollers to support higher loads than three-piece designs. You’ll often find them on crane hooks and kingpins that connect semi-trailers to semi-tractors. However, they rotate at a fraction of the speed of other roller thrust bearings.

Since they come as one piece, you don’t need to assemble cages and washers to install. An outer band holds the rollers inside the raceway, keeping lubricant in and dirt out.

Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.

Sealed—The best choice for dirty environments. In addition to a band, these bearings also have a rubber seal to block dust from creeping in and wearing down the rollers. However, they retain the most heat since air can’t flow through.

Mounted Tapered-Roller Bearings with Four-Bolt Flange

Support heavier loads than mounted ball bearings, but at lower speeds. These bearings also withstand thrust loads, which are forces acting parallel to the shaft. The four-bolt flange supports shafts with a stronger connection to the mounting surface than two-bolt alternatives.

Lubricate your bearings regularly to keep them in tip-top shape. These bearings come packed with grease and sealed to block out dust and contaminants.

Powder-Coated Cast Iron Housing—A rugged iron base coated in thick powder that protects against water, mild detergents, and oil. However, if the coating is scratched or chipped, the underlying iron may rust.

Set Screw—Turn the screw to lock your shaft in place. A simple, reliable choice, set screws grip tightly, but they can mar shaft surfaces.

Mounted Tapered-Roller Bearings

Support heavier loads than mounted ball or needle-roller bearings, but at lower speeds. These bearings also withstand thrust loads, which are forces acting parallel to the shaft. The sturdy housing bolts down to support shafts as they turn.

Lubricate your bearings regularly to keep them in tip-top shape. These bearings come packed with grease and sealed to block out dust and contaminants.

Set Screw—Turn the screw to lock your shaft in place. A simple, reliable choice, set screws grip tightly, but they can mar shaft surfaces.
