How the RNAO16X24X13-XL model number is decoded

envelope 16×24×13 mm: 16 mm seat is the hardened and ground shaft journal itself — there is no inner ring, with a thin 4.0 mm radial section packed with small-diameter needle rollers C is 10.1 kN and C0 11.8 kN at the 16 mm seat; the C/C0 ratio of 0.86 is characteristic of a needle bearing — high static rating relative to dynamic in a compact 24 mm outside diameter the fatigue load limit Cur is 1.93 kN, the limiting speed 23,600 r/min and the thermal reference speed 16,800 r/min; for small needle bearings the reference speed can exceed the kinematic limit, so the lower of the two governs the application dynamic capacity per millimetre of bore is 0.63 kN/mm and per millimetre of width 0.78 kN/mm — the reason 13 mm-wide needle bearings routinely replace much larger ball or roller positions mass is 21 g, just 0.07 g per mm² of projected 24×13 mm envelope, which keeps unbalanced forces low in fast-actuating linkages the 16 mm bore falls in the small band, the workhorse size for gearbox planetary positions, hydraulic pumps and general cam and linkage duty With no ribs the rollers can be arranged very freely in the 13 mm width, giving C 10.1 kN at only 24 mm outside diameter — the most compact radial unit in the HR1 needle section Reading RNAO: O denotes the ribless (open-sided) race design; the single roller row runs directly between ground shaft and housing bore -XL means this is an X-life bearing — Schaeffler's upgraded performance level with smoother raceways, so the 10.1 kN C rating and longer nominal life come without an envelope change. Typical applications include gearbox selector and change linkages, planetary gear bearings and copying and printing machine mechanisms, where the 24 mm outside diameter and 10.1 kN dynamic rating match the duty. In gearbox selector and change linkages the unit fits a compact 16 mm seat, and in planetary gear bearings the 21 g mass keeps unbalanced forces low in fast linkages. Designers also specify it for copying and printing machine mechanisms, relying on the 13 mm width and the published 11.8 kN static rating. Without an inner ring the shaft is the raceway: 58–64 HRC and a ground, polished journal are mandatory, not recommendations. Needle bearings are pure-radial units — any thrust must be taken by separate washers or an adjacent bearing, especially on flangeless RNAO/NAO.

Selection pitfalls — read before you substitute

• Without an inner ring the shaft is the raceway: 58–64 HRC and a ground, polished journal are mandatory, not recommendations.
• Needle bearings are pure-radial units — any thrust must be taken by separate washers or an adjacent bearing, especially on flangeless RNAO/NAO.
• Do not press an RNA/NK assembly in through the outer ring when mounting it on a shaft, and vice versa — rolling forces through the wrong ring bruises the raceways.
