How the NA2200-2RSR model number is decoded

envelope 10×30×13.8 mm: the 30 mm outside diameter is the track-running surface — a thick-walled outer ring over a 10 mm bore — and the 13.8 mm width sets the contact width on the mating track the catalogue lists C 7 kN and C0 6.9 kN for the NA22 sealed yoke-type track roller with inner ring; the C/C0 ratio of 1.01 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 1.12 kN at 10 mm bore, equivalent to 0.70 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 13.8 mm contact width the dynamic rating works out to 0.51 kN per millimetre of rolling-element complement mass is 60 g, or 0.14 g per mm² of the 30×13.8 mm track envelope — inertia that the drive must accelerate on every index of the cam 10 mm pin bore and only 60 g: the smallest sizes demand accurate shaft geometry, because the 10.0 mm section leaves no tolerance for a soft or tapered seat C 7 kN and C0 6.9 kN cover the supported-track bending case; the contact seals set the limiting speed at 5,500 r/min Reading NA22..2RSR: sealed flangeless yoke roller with inner ring; the 13.8 mm-wide unit needs lateral location from the adjacent structure With 2RSR seals the 60 g roller is effectively sealed for life — no relubrication path is provided and none is needed over the design life. Typical applications include agricultural and textile cam followers, packaging machine timing mechanisms and robotic arm linear axes, where the 30 mm track diameter and 7 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 60 g mass keeps follower kinetics light. Designers also specify it for robotic arm linear axes, relying on the 13.8 mm width and the published 6.9 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. Flangeless STO/RSTO/RNA22/NA22 rollers need external axial location; circlips or shoulders must control end float or the roller walks off the track.

Typical equipment & failure modes

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.
• Flangeless STO/RSTO/RNA22/NA22 rollers need external axial location; circlips or shoulders must control end float or the roller walks off the track.
• The crowned outer profile tolerates only small skew; a track that departs by more than the catalogue angle still causes edge loading.
