What Are Roller Bearings?

Roller bearings, sometimes called rolling-element bearings, function much like ball bearings by supporting loads while reducing friction.

Unlike ball bearings, roller bearings use cylindrical rolling elements instead of balls to keep the moving parts separated.

These bearings can have one or several rows of rollers; having multiple rows greatly enhances their ability to handle radial loads. Additionally, varying the shape of the rollers helps decrease friction even more and allows the bearings to accommodate both radial and axial forces.

Although roller bearings can support heavier loads than traditional ball bearings, they are typically suited for low-speed applications. Many roller bearings are self-aligning, which helps them compensate for misalignment and mounting errors, reducing the need for maintenance, repairs, and labor.

Available in various shapes and sizes, roller bearings can be tailored for specialized uses. Features like flanges, cages, and multiple rows of bearings further enhance their performance to meet specific requirements.

Cylindrical Roller Bearings

These bearings use rollers that are longer than their diameter, allowing them to handle higher loads than ball bearings. Our cylindrical roller bearings are designed to support heavy radial loads and are suitable for high-speed applications.

Spherical Roller Bearings

Capable of carrying heavy loads even under conditions of misalignment and shaft deflection, spherical roller bearings offer versatile mounting options with cylindrical or tapered bores, with or without sleeve adapters. They come with a variety of internal clearances and retainer types, and can accommodate axial loads in both directions as well as heavy shock loads. These bearings are available in bore sizes ranging from 20 mm up to 900 mm.
