How the RNA2206-2RSR model number is decoded
envelope 35×62×19.8 mm: the 62 mm outside diameter is the track-running surface — a thick-walled outer ring over a 35 mm bore — and the 19.8 mm width sets the contact width on the mating track the catalogue lists C 17 kN and C0 26.5 kN for the RNA22 sealed yoke-type track roller without inner ring; the C/C0 ratio of 0.64 reflects a rolling-element pack sized for heavy static track loading, and the 13.5 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 3.6 kN at 35 mm bore, equivalent to 0.49 kN of dynamic rating per millimetre — the limiting speed is 1,400 r/min and, as for HR1 track rollers, no thermal reference speed is published the 35 mm bore takes the mounting pin or shaft; across the 19.8 mm contact width the dynamic rating works out to 0.86 kN per millimetre of rolling-element complement mass is 284 g, or 0.23 g per mm² of the 62×19.8 mm track envelope — inertia that the drive must accelerate on every index of the cam at 35 mm pin bore this is a mainstream industrial size — conveyor drives, winches and medium gearboxes use the 19.8 mm width as a standard mounting space 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 The sealed 2RSR execution protects the rolling elements in dirty conveyors and cam drives; seal lip drag is the reason for the conservative speed rating. Typical applications include printing press sheet-transfer grippers, glass and ceramic line conveyors and cam drives and indexing tables, where the 62 mm track diameter and 17 kN dynamic rating match the duty. In printing press sheet-transfer grippers the unit fits a compact 35 mm seat, and in glass and ceramic line conveyors the 284 g mass keeps follower kinetics light. Designers also specify it for cam drives and indexing tables, relying on the 19.8 mm width and the published 26.5 kN static rating. 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. Yoke lugs must support the pin on both sides over its full length — single-sided support turns the pin into a cantilever beam.
Typical equipment & failure modes
Common applications
- packaging machine timing mechanisms
- glass and ceramic line conveyors
- agricultural and textile cam followers
- robotic arm linear axes
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
- 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.
- Yoke lugs must support the pin on both sides over its full length — single-sided support turns the pin into a cantilever beam.
- Flangeless STO/RSTO/RNA22/NA22 rollers need external axial location; circlips or shoulders must control end float or the roller walks off the track.
Frequently asked questions
What are the dimensions of the RNA2206-2RSR?
The RNA2206-2RSR is a RNA22 sealed yoke-type track roller without inner ring with 62 mm outside diameter, 35 mm bore and 19.8 mm width, envelope 35×62×19.8 mm. Mass is 284 g.
What does the RNA2206-2RSR designation mean in the FAG/INA HR1 catalogue?
RNA2206-2RSR identifies this RNA22 sealed yoke-type track roller without inner ring in the Schaeffler HR1 rolling bearings catalogue. The envelope is 35×62×19.8 mm and the catalogue ratings are C 17 kN, C0 26.5 kN, Cur 3.6 kN.
What is the load capacity of the RNA2206-2RSR?
The basic dynamic load rating C is 17 kN and the basic static load rating C0 is 26.5 kN; the fatigue load limit Cur is 3.6 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 RNA2206-2RSR?
HR1 lists a limiting speed of 1,400 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 RNA2206-2RSR?
The track should be flat, harder than the roller contact and clean; the crowned 62 mm outer surface tolerates only small angular error. The 35 mm pin must be hardened to 58–64 HRC and ground like a raceway; lateral guidance comes from the adjacent structure on flangeless executions.
