How the RNAO6X13X8-TV-XL model number is decoded

envelope 6×13×8 mm: 6 mm seat is the hardened and ground shaft journal itself — there is no inner ring, with a thin 3.5 mm radial section packed with small-diameter needle rollers C is 2.95 kN and C0 2.28 kN at the 6 mm seat; the C/C0 ratio of 1.29 is characteristic of a needle bearing — high static rating relative to dynamic in a compact 13 mm outside diameter the fatigue load limit Cur is 0.36 kN, the limiting speed 36,500 r/min and the thermal reference speed 48,500 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 0.49 kN/mm and per millimetre of width 0.37 kN/mm — the reason 8 mm-wide needle bearings routinely replace much larger ball or roller positions mass is 6 g, just 0.06 g per mm² of projected 13×8 mm envelope, which keeps unbalanced forces low in fast-actuating linkages at 6 mm bore this is one of the smallest HR1 executions — chosen where a 13 mm envelope must carry line-contact loads that no miniature ball bearing could take With no ribs the rollers can be arranged very freely in the 8 mm width, giving C 2.95 kN at only 13 mm outside diameter — the most compact radial unit in the HR1 needle section Cur 0.36 kN and speeds up to 36,500 r/min suit planetary gears, connecting rods and pump eccentrics where space is dictated by the shaft diameter As an X-life (-XL) bearing it benefits from the optimised surface finish that reduces friction and raises the fatigue strength behind the 0.36 kN Cur value. Reading -TV: an injection-moulded polyamide cage guides the rolling elements — the lightweight choice that keeps the mass at 6 g in the 13 mm envelope. Typical applications include hydraulic and pneumatic pump eccentrics, copying and printing machine mechanisms and agricultural machine pivots and linkages, where the 13 mm outside diameter and 2.95 kN dynamic rating match the duty. In hydraulic and pneumatic pump eccentrics the unit fits a compact 6 mm seat, and in copying and printing machine mechanisms the 6 g mass keeps unbalanced forces low in fast linkages. Designers also specify it for agricultural machine pivots and linkages, relying on the 8 mm width and the published 2.28 kN static rating. Needle bearings are pure-radial units — any thrust must be taken by separate washers or an adjacent bearing, especially on flangeless RNAO/NAO. Open ends draw contamination directly onto the needles; specify sealed or shielded positions in dusty environments rather than relying on grease alone.

Selection pitfalls — read before you substitute

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