How the NATV15 model number is decoded

envelope 15×35×19 mm: the 35 mm outside diameter is the track-running surface — a thick-walled outer ring over a 15 mm bore — and the 19 mm width sets the contact width on the mating track the catalogue lists C 12.6 kN and C0 23.4 kN for the NATV full-complement yoke-type track roller with axial guidance; the C/C0 ratio of 0.54 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 3.25 kN at 15 mm bore, equivalent to 0.84 kN of dynamic rating per millimetre — the limiting speed is 1,600 r/min and, as for HR1 track rollers, no thermal reference speed is published the 15 mm bore takes the mounting pin or shaft; across the 19 mm contact width the dynamic rating works out to 0.66 kN per millimetre of rolling-element complement mass is 109 g, or 0.16 g per mm² of the 35×19 mm track envelope — inertia that the drive must accelerate on every index of the cam at 15 mm pin bore this size balances the 35 mm outside diameter against machineability of the adjacent parts — the most frequently specified band in the HR1 range At 15 mm bore and 109 g the roller mounts on a standard pin; yoke mounting means the pin, not a stud, carries the clamp load The crowned outside surface of the 35 mm outer ring spreads contact stress when the cam track departs slightly from parallel, reducing edge loading Typical applications include agricultural and textile cam followers, packaging machine timing mechanisms and robotic arm linear axes, where the 35 mm track diameter and 12.6 kN dynamic rating match the duty. In agricultural and textile cam followers the unit fits a compact 15 mm seat, and in packaging machine timing mechanisms the 109 g mass keeps follower kinetics light. Designers also specify it for robotic arm linear axes, relying on the 19 mm width and the published 23.4 kN static rating. Sealed PP/2RSR units are greased for life: never add a grease nipple, and respect the lower limiting speed imposed by the rubbing lips. The crowned outer profile tolerates only small skew; a track that departs by more than the catalogue angle still causes edge loading.

Selection pitfalls — read before you substitute

• Sealed PP/2RSR units are greased for life: never add a grease nipple, and respect the lower limiting speed imposed by the rubbing lips.
• The crowned outer profile tolerates only small skew; a track that departs by more than the catalogue angle still causes edge loading.
• 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.
