How the RNA2202-2RSR model number is decoded

envelope 20×35×13.8 mm: the 35 mm outside diameter is the track-running surface — a thick-walled outer ring over a 20 mm bore — and the 13.8 mm width sets the contact width on the mating track the catalogue lists C 7.6 kN and C0 9.9 kN for the RNA22 sealed yoke-type track roller without inner ring; the C/C0 ratio of 0.77 reflects a rolling-element pack sized for heavy static track loading, and the 7.5 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 1.39 kN at 20 mm bore, equivalent to 0.38 kN of dynamic rating per millimetre — the limiting speed is 3,400 r/min and, as for HR1 track rollers, no thermal reference speed is published the 20 mm bore takes the mounting pin or shaft; across the 13.8 mm contact width the dynamic rating works out to 0.55 kN per millimetre of rolling-element complement mass is 60 g, or 0.12 g per mm² of the 35×13.8 mm track envelope — inertia that the drive must accelerate on every index of the cam the 20 mm pin bore falls in the small band, the workhorse size for gearbox planetary positions, hydraulic pumps and general cam and linkage duty C 7.6 kN, C0 9.9 kN and Cur 1.39 kN are the track-load ratings; the sealed lips reduce the limiting speed to 3,400 r/min The sealed pack is greased for life — additional lubrication is neither possible nor required, and the roller suits dirty positions with no maintenance access The 2RSR suffix fits elastomer contact seals on both sides, retaining the life-long grease fill behind the 35 mm outer ring. Typical applications include printing press sheet-transfer grippers, glass and ceramic line conveyors and cam drives and indexing tables, where the 35 mm track diameter and 7.6 kN dynamic rating match the duty. In printing press sheet-transfer grippers the unit fits a compact 20 mm seat, and in glass and ceramic line conveyors the 60 g mass keeps follower kinetics light. Designers also specify it for cam drives and indexing tables, relying on the 13.8 mm width and the published 9.9 kN static rating. The crowned outer profile tolerates only small skew; a track that departs by more than the catalogue angle still causes edge loading. 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

Common applications

  • cam drives and indexing tables
  • automatic assembly machine carriages
  • woodworking machine feed tracks
  • packaging machine timing mechanisms

Known failure patterns

  • outer-ring fatigue cracking across the unsupported track zone under excessive static load
  • track-side brinelling when the mating rail is softer than the roller running surface
  • flat spots from standing loads or very short oscillating strokes on full-complement rollers
  • seal lip failure and grease loss after sustained running above the limiting speed (PP/2RSR executions)
  • edge wear from skewed tracks that exceed the crowned-profile correction range
  • pin-seat fretting where a hard journal requirement (RSTO/RNA22) was met with a soft pin
  • roller walk-off in flangeless STO/RSTO executions with uncontrolled lateral float
  • contamination entry through open sides in dusty or wash-down environments
  • cage fracture in caged NATR/STO rollers exposed to heavy shock

Selection pitfalls — read before you substitute

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

Frequently asked questions

What are the dimensions of the RNA2202-2RSR?

The RNA2202-2RSR is a RNA22 sealed yoke-type track roller without inner ring with 35 mm outside diameter, 20 mm bore and 13.8 mm width, envelope 20×35×13.8 mm. Mass is 60 g.

What does the RNA2202-2RSR designation mean in the FAG/INA HR1 catalogue?

RNA2202-2RSR identifies this RNA22 sealed yoke-type track roller without inner ring in the Schaeffler HR1 rolling bearings catalogue. The envelope is 20×35×13.8 mm and the catalogue ratings are C 7.6 kN, C0 9.9 kN, Cur 1.39 kN.

What is the load capacity of the RNA2202-2RSR?

The basic dynamic load rating C is 7.6 kN and the basic static load rating C0 is 9.9 kN; the fatigue load limit Cur is 1.39 kN. For track rollers these values already cover the thick-walled outer ring bending case on an unsupported track.

What is the maximum speed of the RNA2202-2RSR?

HR1 lists a limiting speed of 3,400 r/min for track rollers and no thermal reference speed. The crowned thick-walled outer ring and (on stud types) the stud contact make the limiting speed the governing figure.

What must the mating track and pin look like for the RNA2202-2RSR?

The track should be flat, harder than the roller contact and clean; the crowned 35 mm outer surface tolerates only small angular error. The 20 mm pin must be hardened to 58–64 HRC and ground like a raceway; lateral guidance comes from the adjacent structure on flangeless executions.
