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

Mounting holes on the inner and outer rings allow for fastening onto hollow joints and shafts. The rollers face in alternating directions to allow for rigid, accurate motion under any combination of radial, thrust, and moment (twisting) loads. Use in applications where highly accurate motion is necessary, such as machine tools and industrial robots.

Open bearings dissipate heat more efficiently than sealed bearings.

Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

With a considerably larger ID than our Face-Mount Crossed-Roller Bearings, use these to run hydraulic lines, electrical wiring, and other components through the inside of the bearing. The rollers face in alternating directions to allow for rigid, accurate motion under any combination of radial, thrust, and moment (twisting) loads. Use in applications where highly accurate motion is necessary, such as machine tools and industrial robots.

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.

A built-in thrust ball bearing reduces wear from adjacent shaft components, while the needle rollers support high radial loads. Install anywhere you would use separate bearings for radial and thrust loads.

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. These bearings can be taken apart, so you can install them with precision and quickly dismantle them for maintenance or replacement.

Bearings for combined radial and thrust loads have an inner ring that's flanged on one side, so they only allow heat expansion in one direction.

The tapered rollers in these bearings support large shafts at high static loads. Seals block out dust and contaminants.
