The needle bearings according to DIN 5405-1/ISO 3030 are highly developed structural units 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 bearings offer high load capacity and are optimized for high speeds, enhancing their efficiency in various industrial applications. Assembly is straightforward, and with precise execution of the raceways, high running 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 operation, 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 up to 146,000 N statically
• Suitable for high speeds and precise applications
• Easy assembly and high running accuracy.
