How the RNAO22X35X16-XL model number is decoded

envelope 22×35×16 mm: 22 mm seat is the hardened and ground shaft journal itself — there is no inner ring, with a thin 6.5 mm radial section packed with small-diameter needle rollers C is 22.6 kN and C0 25.5 kN at the 22 mm seat; the C/C0 ratio of 0.89 is characteristic of a needle bearing — high static rating relative to dynamic in a compact 35 mm outside diameter the fatigue load limit Cur is 4.25 kN, the limiting speed 19,200 r/min and the thermal reference speed 11,200 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 1.03 kN/mm and per millimetre of width 1.41 kN/mm — the reason 16 mm-wide needle bearings routinely replace much larger ball or roller positions mass is 59 g, just 0.11 g per mm² of projected 35×16 mm envelope, which keeps unbalanced forces low in fast-actuating linkages the 22 mm bore falls in the small band, the workhorse size for gearbox planetary positions, hydraulic pumps and general cam and linkage duty At 59 g the assembly is easy to drop into a connecting-rod eye, but without ribs even a small axial offset skews the needles — end float must be controlled by the surrounding parts X-life status (-XL) indicates the current Schaeffler premium execution at 22 mm bore; the 25.5 kN C0 rating reflects the improved rolling-contact geometry. Typical applications include copying and printing machine mechanisms, gearbox selector and change linkages and hydraulic and pneumatic pump eccentrics, where the 35 mm outside diameter and 22.6 kN dynamic rating match the duty. In copying and printing machine mechanisms the unit fits a compact 22 mm seat, and in gearbox selector and change linkages the 59 g mass keeps unbalanced forces low in fast linkages. Designers also specify it for hydraulic and pneumatic pump eccentrics, relying on the 16 mm width and the published 25.5 kN static rating. 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. Adding an IR inner ring changes the envelope logic: the same outer assembly then fits a smaller shaft — recheck bore, clearance and ratings when substituting.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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.
• Adding an IR inner ring changes the envelope logic: the same outer assembly then fits a smaller shaft — recheck bore, clearance and ratings when substituting.
• Keep the specified radial clearance; an oversized shaft or heavy interference removes it and the needles bind hot immediately.
