The needle bearing is a highly developed bearing solution manufactured according to the standards DIN 5405-1 and ISO 3030. This assembly consists of cages and needle rollers and is available in single-row or double-row designs. The single-row variant is characterized by a radial height that corresponds to the diameter of the needle rollers, allowing for a compact design. Needle bearings are known for their high load capacity and suitability for high speeds, making them an ideal choice for demanding applications. Assembly is straightforward, and with precise execution of the raceways, high running accuracy is achieved. The radial clearance can be adjusted by selecting the type of needle roller as well as by shaft and housing tolerances. For optimal performance, it is important that the raceways on the shaft and in the housing are hardened and ground. Double-row needle bearings are available in specific outer diameters and carry the suffix ZW.

• Single or double-row design for flexible applications
• High load capacity and suitability for high speeds
• Compact design with minimal radial space requirement
• Easy assembly and high running accuracy.
