This needle roller bearing carries a solid inner ring and full complement of needle rollers arranged in dimension series 49, giving high radial load capacity within a compact cross-section. Bore diameter is 12.0 mm, outside diameter 24.0 mm, and net mass is 27.3 g. Sealing on both sides is provided by lip seals, designation 2RSR. The double-sided lip seal design retains grease inside the bearing and blocks contaminants from entering the raceway, so the unit is suited for radial loads where a compact, self-contained needle bearing with a solid inner ring is required. Because the seals are integrated, no external sealing arrangement is needed, and the bearing can be mounted directly onto a shaft matching the 12.0 mm bore without additional shielding components.
