They comprise a kind of roller bearings having rolling elements of considerable length with a relatively small diameter. These products are designed primarily for taking the radial loads. Since the force on the rollers during the operation of the bearing is distributed along an extended line, such parts have a high load capacity. In this case, the speed characteristics of needle bearings are relatively small. Due to the small-diameter rollers, the needle models have a small thickness, which allows them to be used where free space is limited.
