Description
This needle roller bearing carries a full complement of needle rollers in a single row, combined with a solid inner ring and an outer ring featuring two ribs (bords) that locate the roller set axially on both sides. Bore diameter is 100.0 mm, outside diameter 140.0 mm, and width 40.0 mm, with a net mass of 1.926 kg. The bearing is rated for a limiting speed of 4000 1/min and a reference speed of 2550 1/min, and it is fitted with a standard cage. The two-rib outer ring allows the bearing to take up radial load while keeping the roller set positively guided within the housing bore, without needing a separate locating shoulder on the outside. As a solid unit with inner ring, it can be mounted directly onto the shaft, simplifying fitting compared to needle sleeves without an inner ring. The standard cage design and the given speed ratings define the operating limits for continuous radial-load duty, while the compact cross-section for this bore size makes it suitable where limited radial space is combined with the need for a self-contained, positively guided needle bearing unit.
