The needle roller bearings according to DIN 5405-1/ISO 3030 are highly developed components consisting of cages and needle rollers. They are available in single or double-row designs and are characterized by their compact construction, as the radial height corresponds only to the diameter of the needle rollers. This design allows for a bearing with minimal radial space, making them particularly suitable for applications with limited space. Needle roller bearings offer high load capacity and are optimized for high speeds, which expands their applicability in various machines and devices. Assembly is straightforward, and with precise execution of the raceways, high roundness accuracy is achieved. The radial clearance values can be influenced by the choice of needle roller type as well as by the tolerances of the shaft and housing. For optimal function, it is necessary that the raceways on the shaft and in the housing are hardened and ground.

• Compact design for minimal radial space
• High load capacity for demanding applications
• Suitable for high speeds and precise bearings
• Easy assembly due to thoughtful design.
