This needle roller bearing is a double row design (ZW) with a bore diameter of 75.0 mm, outside diameter of 105.0 mm, and width of 54.0 mm. Net mass is 1.41 kg. The bearing is fitted with a standard cage and carries a full complement of needle rollers arranged in two rows within dimension series 69, giving high radial load capacity for its cross-section. Limiting speed is rated at 5400 1/min, with a reference speed of 3150 1/min. The double row arrangement provides increased radial rigidity and load distribution compared to a single row design of the same bore, making it suitable for applications requiring compact radial support without axial guidance built into the bearing itself. As this is a bearing without an inner ring, the shaft seat must be machined and hardened to serve as the raceway. The standard cage guides the needle rollers and maintains even spacing, supporting operation up to the stated reference and limiting speed values.
