How the RNA22-6-2RSR model number is decoded

envelope 10×19×11.8 mm: the 19 mm outside diameter is the track-running surface — a thick-walled outer ring over a 10 mm bore — and the 11.8 mm width sets the contact width on the mating track the catalogue lists C 3.9 kN and C0 3.7 kN for the RNA22 sealed yoke-type track roller without inner ring; the C/C0 ratio of 1.05 reflects a rolling-element pack sized for heavy static track loading, and the 4.5 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 0.495 kN at 10 mm bore, equivalent to 0.39 kN of dynamic rating per millimetre — the limiting speed is 9,000 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 11.8 mm contact width the dynamic rating works out to 0.33 kN per millimetre of rolling-element complement mass is 18 g, or 0.08 g per mm² of the 19×11.8 mm track envelope — inertia that the drive must accelerate on every index of the cam 10 mm pin bore and only 18 g: the smallest sizes demand accurate shaft geometry, because the 4.5 mm section leaves no tolerance for a soft or tapered seat C 3.9 kN, C0 3.7 kN and Cur 0.495 kN are the track-load ratings; the sealed lips reduce the limiting speed to 9,000 r/min Choose RNA22 over RSTO where the environment carries abrasives: the 2RSR lips protect the needle complement but cannot be inspected or replaced without scrapping the unit Reading the suffix: 2RSR is the FAG/INA code for rubbing lip seals at both faces, making the 10 mm-bore unit greased for life. Typical applications include conveyor transfer and diverting stations, robotic arm linear axes and automotive welding jig rollers, where the 19 mm track diameter and 3.9 kN dynamic rating match the duty. In conveyor transfer and diverting stations the unit fits a compact 10 mm seat, and in robotic arm linear axes the 18 g mass keeps follower kinetics light. Designers also specify it for automotive welding jig rollers, relying on the 11.8 mm width and the published 3.7 kN static rating. 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. 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

• 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.
• Sealed PP/2RSR units are greased for life: never add a grease nipple, and respect the lower limiting speed imposed by the rubbing lips.
• Yoke lugs must support the pin on both sides over its full length — single-sided support turns the pin into a cantilever beam.
