How the NA69-22-XL model number is decoded

envelope 22×39×30 mm: 22 mm bore accepts a normal-tolerance machined shaft via the integral inner ring, with a thin 8.5 mm radial section packed with small-diameter needle rollers C is 42 kN and C0 55 kN at the 22 mm seat; the C/C0 ratio of 0.76 is characteristic of a needle bearing — high static rating relative to dynamic in a compact 39 mm outside diameter the fatigue load limit Cur is 10 kN, the limiting speed 15,300 r/min and the thermal reference speed 7,900 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 1.91 kN/mm and per millimetre of width 1.40 kN/mm — the reason 30 mm-wide needle bearings routinely replace much larger ball or roller positions mass is 150 g, just 0.13 g per mm² of projected 39×30 mm envelope, which keeps unbalanced forces low in fast-actuating linkages at 22 mm bore this size balances the 39 mm outside diameter against machineability of the adjacent parts — the most frequently specified band in the HR1 range NA69/22-XL is supplied with a machined inner ring, so it mounts on an ordinary turned and ground shaft of normal tolerance — hardening the journal is not required The inner ring is separable, so the outer-ring/roller assembly can be pressed into the housing first; the 55 kN C0 rating still assumes full rigid support under both rings X-life status (-XL) indicates the current Schaeffler premium execution at 22 mm bore; the 55 kN C0 rating reflects the improved rolling-contact geometry. Typical applications include motorcycle and light-vehicle transmissions, connecting-rod small ends and two-stroke and compressor piston pins, where the 39 mm outside diameter and 42 kN dynamic rating match the duty. In motorcycle and light-vehicle transmissions the unit fits a compact 22 mm seat, and in connecting-rod small ends the 150 g mass keeps unbalanced forces low in fast linkages. Designers also specify it for two-stroke and compressor piston pins, relying on the 30 mm width and the published 55 kN static rating. Without an inner ring the shaft is the raceway: 58–64 HRC and a ground, polished journal are mandatory, not recommendations. On reciprocating duty ensure the stroke rotates the full needle set, or brinelling occurs at the same roller positions.

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.
• On reciprocating duty ensure the stroke rotates the full needle set, or brinelling occurs at the same roller positions.
• 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.
