Needle roller bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. This type of roller is called a needle roller. Despite its small cross-section, the bearings have a high load carrying capacity and are therefore particularly suitable for applications where radial space is limited. The contour of the needle roller is slightly contracted at the proximal end face. The result of contact correction between the needle roller and the raceway avoids damaging edge stresses.
