How the RNAO10X17X10-TV-XL model number is decoded
envelope 10×17×10 mm: 10 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 5.3 kN and C0 5.5 kN at the 10 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 28,000 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 0.53 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 10 g, just 0.06 g per mm² of projected 17×10 mm envelope, which keeps unbalanced forces low in fast-actuating linkages the 10 mm bore sits in the miniature band; at 10 mm wide the RNAO10×17×10-TV-XL is built into compact cam drives, indexing pawls and light linkages With no ribs the rollers can be arranged very freely in the 10 mm width, giving C 5.3 kN at only 17 mm outside diameter — the most compact radial unit in the HR1 needle section At 10 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 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 10×17×10 mm envelope. -TV denotes the PA66 cage: light, quiet and self-lubricating in dry-running moments, but limited by the polymer's continuous-temperature ceiling well below the ring steel's. Typical applications include rocker arms and valve trains, two-stroke and compressor piston pins and small electric motor accessory drives, where the 17 mm outside diameter and 5.3 kN dynamic rating match the duty. In rocker arms and valve trains the unit fits a compact 10 mm seat, and in two-stroke and compressor piston pins the 10 g mass keeps unbalanced forces low in fast linkages. Designers also specify it for small electric motor accessory drives, relying on the 10 mm width and the published 5.5 kN static rating. Keep the specified radial clearance; an oversized shaft or heavy interference removes it and the needles bind hot immediately. Needle bearings are pure-radial units — any thrust must be taken by separate washers or an adjacent bearing, especially on flangeless RNAO/NAO.
Typical equipment & failure modes
Common applications
- rocker arms and valve trains
- textile machine heald and cam shafts
- small electric motor accessory drives
- planetary gear bearings
Known failure patterns
- journal brinelling when a no-inner-ring bearing runs on a shaft hardened below 58 HRC or finished too rough
- needle skewing and jamming after momentary unloading of a flangeless (RNAO/NAO) pack
- raceway pitting from contamination drawn through the open ends of an unsealed bearing
- edge loading at the roller ends from a tapered or lobed shaft seat
- cage damage from shock loading or from pressing the bearing through the wrong ring
- lubricant starvation on fast reciprocating strokes that never fully rotate the needles
- false brinelling during stationary transport vibration
- spalling from excessive interference that removes the radial clearance
- roller wear from misaligned connecting-rod eyes and rocker bores
Selection pitfalls — read before you substitute
- Keep the specified radial clearance; an oversized shaft or heavy interference removes it and the needles bind hot immediately.
- Needle bearings are pure-radial units — any thrust must be taken by separate washers or an adjacent bearing, especially on flangeless RNAO/NAO.
- 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.
Frequently asked questions
What are the dimensions of the RNAO10×17×10-TV-XL?
The RNAO10×17×10-TV-XL is a RNAO flangeless needle roller bearing without inner ring with 17 mm outside diameter, 10 mm bore and 10 mm width, envelope 10×17×10 mm. Mass is 10 g.
What does the RNAO10×17×10-TV-XL designation mean in the FAG/INA HR1 catalogue?
RNAO10×17×10-TV-XL identifies this RNAO flangeless needle roller bearing without inner ring in the Schaeffler HR1 rolling bearings catalogue; the -XL suffix marks the X-life execution. The envelope is 10×17×10 mm and the catalogue ratings are C 5.3 kN, C0 5.5 kN, Cur 0.94 kN.
What is the load capacity of the RNAO10×17×10-TV-XL?
The basic dynamic load rating C is 5.3 kN and the basic static load rating C0 is 5.5 kN; the fatigue load limit Cur is 0.94 kN.
What is the maximum speed of the RNAO10×17×10-TV-XL?
The limiting speed is 29,500 r/min and the thermal reference speed is 28,000 r/min. In the Schaeffler catalogue the reference speed is the thermally permissible running speed under defined load; the lower of the two values governs each application.
Can the RNAO10×17×10-TV-XL run directly on an ordinary shaft?
Not on a soft shaft. The RNAO10×17×10-TV-XL has no inner ring, so the 10 mm journal itself is the raceway: harden it to 58–64 HRC and finish-grind to the catalogue journal tolerance. Where the shaft cannot be hardened, use the corresponding with-inner-ring execution instead.
