Description
Carries radial loads through a full complement of needle rollers guided between a solid inner ring and an outer ring with two ribs, giving a compact cross-section for the 40.0 mm bore. Outside diameter is 62.0 mm and width 22.0 mm, with a net mass of 0.234 kg. The bearing reaches a limiting speed of 9200.0 1/min and a reference speed of 5000.0 1/min, running with a standard cage. The two-rib outer ring locates the needle roller set axially and keeps the inner ring positioned relative to the housing bore, so the bearing can be mounted as a self-contained unit without a separate shaft washer. Load capacity per unit cross-section benefits from the full needle complement, while the standard cage version is suited to applications where roller-to-roller contact is acceptable at the given speed range. Lubrication and sealing are to be arranged externally, as no built-in seals are specified for this design.
