How the NAO6X17X10-TV-IS1-XL model number is decoded

envelope 6×17×10 mm: 6 mm bore accepts a normal-tolerance machined shaft via the integral inner ring, with a thin 5.5 mm radial section packed with small-diameter needle rollers C is 5.3 kN and C0 5.5 kN at the 6 mm seat; the C/C0 ratio of 0.96 is characteristic of a needle bearing — high static rating relative to dynamic in a compact 17 mm outside diameter the fatigue load limit Cur is 0.94 kN, the limiting speed 29,500 r/min and the thermal reference speed 23,800 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 0.88 kN/mm and per millimetre of width 0.53 kN/mm — the reason 10 mm-wide needle bearings routinely replace much larger ball or roller positions mass is 14 g, just 0.08 g per mm² of projected 17×10 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 17 mm envelope must carry line-contact loads that no miniature ball bearing could take The single needle row fills the thin section, with limiting speed 29,500 r/min and reference speed 23,800 r/min With the inner ring fitted the shaft seat stays at normal bearing-shaft tolerance; C0 is 5.5 kN and Cur 0.94 kN for the 14 g unit 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 6×17×10 mm envelope. The -TV cage is part of the speed story here: cage-guided kinematics permit the published 29,500 r/min limiting speed without roller-to-roller sliding. The IS1 groove keeps the flangeless races lubricable from the shaft side despite the compact 5.5 mm section. Typical applications include copying and printing machine mechanisms, gearbox selector and change linkages and hydraulic and pneumatic pump eccentrics, where the 17 mm outside diameter and 5.3 kN dynamic rating match the duty. In copying and printing machine mechanisms the unit fits a compact 6 mm seat, and in gearbox selector and change linkages the 14 g mass keeps unbalanced forces low in fast linkages. Designers also specify it for hydraulic and pneumatic pump eccentrics, relying on the 10 mm width and the published 5.5 kN static rating. On reciprocating duty ensure the stroke rotates the full needle set, or brinelling occurs at the same roller positions. 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.

Selection pitfalls — read before you substitute

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