How the NATV6-PP model number is decoded

envelope 6×19×12 mm: the 19 mm outside diameter is the track-running surface — a thick-walled outer ring over a 6 mm bore — and the 12 mm width sets the contact width on the mating track the catalogue lists C 5.4 kN and C0 8.1 kN for the NATV full-complement yoke-type track roller with axial guidance; the C/C0 ratio of 0.67 reflects a rolling-element pack sized for heavy static track loading, and the 6.5 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 1.19 kN at 6 mm bore, equivalent to 0.90 kN of dynamic rating per millimetre — the limiting speed is 3,100 r/min and, as for HR1 track rollers, no thermal reference speed is published the 6 mm bore takes the mounting pin or shaft; across the 12 mm contact width the dynamic rating works out to 0.45 kN per millimetre of rolling-element complement mass is 21 g, or 0.09 g per mm² of the 19×12 mm track envelope — inertia that the drive must accelerate on every index of the cam 6 mm pin bore and only 21 g: the smallest sizes demand accurate shaft geometry, because the 6.5 mm section leaves no tolerance for a soft or tapered seat Reading NATR/NATV: yoke rollers with inner ring and integral axial guidance; the PP suffix adds lip seals on both sides and a life-long grease fill The outer-ring ribs give axial guidance, so the roller tolerates light thrust from skewed tracks without external flanges; the 12 mm width covers most standard cam geometries -PP protection suits cams and rails that are washed down or run in dust; exceeding the 3,100 r/min speed ceiling overheats the lips rather than just accelerating wear. Typical applications include cam drives and indexing tables, printing press sheet-transfer grippers and woodworking machine feed tracks, where the 19 mm track diameter and 5.4 kN dynamic rating match the duty. In cam drives and indexing tables the unit fits a compact 6 mm seat, and in printing press sheet-transfer grippers the 21 g mass keeps follower kinetics light. Designers also specify it for woodworking machine feed tracks, relying on the 12 mm width and the published 8.1 kN static rating. Flangeless STO/RSTO/RNA22/NA22 rollers need external axial location; circlips or shoulders must control end float or the roller walks off the track. Sealed PP/2RSR units are greased for life: never add a grease nipple, and respect the lower limiting speed imposed by the rubbing lips.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Flangeless STO/RSTO/RNA22/NA22 rollers need external axial location; circlips or shoulders must control end float or the roller walks off the track.
• Sealed PP/2RSR units are greased for life: never add a grease nipple, and respect the lower limiting speed imposed by the rubbing lips.
• Check the mating track hardness and flatness — a soft or scalloped rail fails before the 19 mm outer ring does.
