This needle roller bearing carries a solid inner ring and is built in dimension series 49, with a bore diameter of 45.0 mm, an outside diameter of 68.0 mm, and a net mass of 283.84 g. The full complement of needle rollers is guided within the design, and lip seals are fitted on both sides, designated 2RSR, sealing the bearing from both faces. The double-sided lip sealing keeps contaminants out of the roller path and retains lubricant inside the bearing, reducing the need for frequent relubrication. The compact cross-section typical of the 49 dimension series gives a high load capacity relative to the outside diameter, making this bearing suitable where radial space is limited but a rigid, sealed needle roller arrangement is required.
