How the NATR10 model number is decoded

envelope 10×30×15 mm: the 30 mm outside diameter is the track-running surface — a thick-walled outer ring over a 10 mm bore — and the 15 mm width sets the contact width on the mating track the catalogue lists C 6.8 kN and C0 8.7 kN for the NATR yoke-type track roller with cage and axial guidance; the C/C0 ratio of 0.78 reflects a rolling-element pack sized for heavy static track loading, and the 10.0 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 1.24 kN at 10 mm bore, equivalent to 0.68 kN of dynamic rating per millimetre — the limiting speed is 5,500 r/min and, as for HR1 track rollers, no thermal reference speed is published the 10 mm bore takes the mounting pin or shaft; across the 15 mm contact width the dynamic rating works out to 0.45 kN per millimetre of rolling-element complement mass is 64 g, or 0.14 g per mm² of the 30×15 mm track envelope — inertia that the drive must accelerate on every index of the cam at 10 mm pin bore this is one of the smallest HR1 executions — chosen where a 30 mm envelope must carry line-contact loads that no miniature ball bearing could take At 10 mm bore and 64 g the roller mounts on a standard pin; yoke mounting means the pin, not a stud, carries the clamp load Typical applications include agricultural and textile cam followers, packaging machine timing mechanisms and robotic arm linear axes, where the 30 mm track diameter and 6.8 kN dynamic rating match the duty. In agricultural and textile cam followers the unit fits a compact 10 mm seat, and in packaging machine timing mechanisms the 64 g mass keeps follower kinetics light. Designers also specify it for robotic arm linear axes, relying on the 15 mm width and the published 8.7 kN static rating. Full-complement NATV/NUTR/PWTR rollers make heat and flat-spot easily — slow continuous rotation is fine, stationary load on a turning track is not. The crowned outer profile tolerates only small skew; a track that departs by more than the catalogue angle still causes edge loading.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Full-complement NATV/NUTR/PWTR rollers make heat and flat-spot easily — slow continuous rotation is fine, stationary load on a turning track is not.
• The crowned outer profile tolerates only small skew; a track that departs by more than the catalogue angle still causes edge loading.
• Check the mating track hardness and flatness — a soft or scalloped rail fails before the 30 mm outer ring does.
