Needle Roller Bearings

Needle Roller Bearings consist of massive outer rings, needle roller and cage assemblies and removable inner rings. Their high radial load carrying capacity and compact design make them ideal for applications with limited space. They are widely used in a variety of sectors, including automotive, aircraft, construction and agriculture.

Needle roller bearings are often used as non-locating bearings since they can support high radial forces while maintaining low axial stiffness. This characteristic allows them to compensate for axial displacements and angular deviations between the shaft and housing. Due to this flexibility, needle roller bearings guarantee reliable and precise bearing support.

Single-row needle roller bearings consist of a single row of needle rollers arranged in a retainer. Due to their high length-to-diameter ratio, they are particularly well suited to supporting high radial loads. Single row needle roller bearings offer good load carrying capacity and are available in a variety of sizes and designs.

Double-row needle roller bearings, instead, have two separate rows of needle rollers spaced apart by an inner or centering ring. This allows higher load carrying capacity and axial load capacity. They are suitable for high radial loads and certain axial loads. They are often used in situations requiring increased load carrying capacity, such as in gearboxes, couplings or slewing rings.
