How the NATV8-PP model number is decoded

envelope 8×24×15 mm: the 24 mm outside diameter is the track-running surface — a thick-walled outer ring over a 8 mm bore — and the 15 mm width sets the contact width on the mating track the catalogue lists C 7.8 kN and C0 11.7 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 8.0 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 1.62 kN at 8 mm bore, equivalent to 0.97 kN of dynamic rating per millimetre — the limiting speed is 2,500 r/min and, as for HR1 track rollers, no thermal reference speed is published the 8 mm bore takes the mounting pin or shaft; across the 15 mm contact width the dynamic rating works out to 0.52 kN per millimetre of rolling-element complement mass is 41 g, or 0.11 g per mm² of the 24×15 mm track envelope — inertia that the drive must accelerate on every index of the cam 8 mm pin bore and only 41 g: the smallest sizes demand accurate shaft geometry, because the 8.0 mm section leaves no tolerance for a soft or tapered seat NATV is the full-complement yoke-type track roller: cageless needle rollers pack the 24 mm envelope for maximum C0 11.7 kN, guided axially by the outer-ring ribs Without a cage the NATV trades speed for static capacity — the limiting speed is 2,500 r/min, with C 7.8 kN and C0 11.7 kN The -PP suffix fits contact lip seals on both sides, retaining the factory grease and excluding water and dust; seal friction is reflected in the 2,500 r/min limiting speed. Typical applications include automotive welding jig rollers, conveyor transfer and diverting stations and automatic assembly machine carriages, where the 24 mm track diameter and 7.8 kN dynamic rating match the duty. In automotive welding jig rollers the unit fits a compact 8 mm seat, and in conveyor transfer and diverting stations the 41 g mass keeps follower kinetics light. Designers also specify it for automatic assembly machine carriages, relying on the 15 mm width and the published 11.7 kN static rating. Yoke lugs must support the pin on both sides over its full length — single-sided support turns the pin into a cantilever beam. The pin or shaft is part of the bearing system: harden it for RSTO/RNA22 positions, and size its deflection because the roller cannot compensate for a bent pin.

Selection pitfalls — read before you substitute

• Yoke lugs must support the pin on both sides over its full length — single-sided support turns the pin into a cantilever beam.
• The pin or shaft is part of the bearing system: harden it for RSTO/RNA22 positions, and size its deflection because the roller cannot compensate for a bent pin.
• Flangeless STO/RSTO/RNA22/NA22 rollers need external axial location; circlips or shoulders must control end float or the roller walks off the track.
