This needle roller bearing is a single row design with a solid inner ring and an outer ring featuring two ribs, providing full radial support and axial location of the roller set. Bore diameter is 20.0 mm, outside diameter 37.0 mm, and width 17.0 mm, with a net mass of 77.76 g. The bearing is fitted with a standard cage. Limiting speed reaches 16900 1/min, while the reference speed is rated at 9400 1/min. The full complement of needle rollers combined with the ribbed outer ring allows the bearing to carry radial loads within a compact cross-section, making efficient use of available housing space. Since both rings are integrated into the design, mounting is simplified and internal alignment between rolling elements is maintained without additional locating components. The standard cage guides the rollers evenly around the raceway, supporting stable operation up to the stated reference speed under correct lubrication conditions.
