How the RNA6916-ZW-XL model number is decoded

envelope 90×110×54 mm: 90 mm seat is the hardened and ground shaft journal itself — there is no inner ring, with a thin 10.0 mm radial section packed with small-diameter needle rollers C is 153 kN and C0 300 kN at the 90 mm seat; the C/C0 ratio of 0.51 is characteristic of a needle bearing — high static rating relative to dynamic in a compact 110 mm outside diameter the fatigue load limit Cur is 54 kN, the limiting speed 5,100 r/min and the thermal reference speed 3,050 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 1.70 kN/mm and per millimetre of width 2.83 kN/mm — the reason 54 mm-wide needle bearings routinely replace much larger ball or roller positions mass is 987 g, just 0.17 g per mm² of projected 110×54 mm envelope, which keeps unbalanced forces low in fast-actuating linkages at 90 mm bore the 110 mm outside diameter and 54 mm width target rolling stands, construction machinery and heavy gearboxes; the limiting speed drops to 5,100 r/min With Cur 54 kN and a 5,100 r/min limiting speed the unit suits pivots, rocker arms, pumps and compact gear trains running on hardened pins The -XL suffix marks the X-life execution: refined raceway topography and upgraded materials lift the basic ratings versus the non-X-life bearing at the same 90×110×54 mm envelope. Reading -ZW: two needle rows instead of one; the load is spread over the 54 mm width while the outside diameter stays a compact 110 mm. Typical applications include planetary gear bearings, small electric motor accessory drives and gearbox selector and change linkages, where the 110 mm outside diameter and 153 kN dynamic rating match the duty. In planetary gear bearings the unit fits a compact 90 mm seat, and in small electric motor accessory drives the 987 g mass keeps unbalanced forces low in fast linkages. Designers also specify it for gearbox selector and change linkages, relying on the 54 mm width and the published 300 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. Open ends draw contamination directly onto the needles; specify sealed or shielded positions in dusty environments rather than relying on grease alone.

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.
• Open ends draw contamination directly onto the needles; specify sealed or shielded positions in dusty environments rather than relying on grease alone.
• Needle bearings are pure-radial units — any thrust must be taken by separate washers or an adjacent bearing, especially on flangeless RNAO/NAO.
