How the PWTR30-2RS-XL model number is decoded

envelope 30×62×29 mm: the 62 mm outside diameter is the track-running surface — a thick-walled outer ring over a 30 mm bore — and the 29 mm width sets the contact width on the mating track the catalogue lists C 35 kN and C0 46 kN for the PWTR sealed double-row full-complement yoke-type track roller; the C/C0 ratio of 0.76 reflects a rolling-element pack sized for heavy static track loading, and the 16.0 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 5.9 kN at 30 mm bore, equivalent to 1.17 kN of dynamic rating per millimetre — the limiting speed is 2,200 r/min and, as for HR1 track rollers, no thermal reference speed is published the 30 mm bore takes the mounting pin or shaft; across the 29 mm contact width the dynamic rating works out to 1.21 kN per millimetre of rolling-element complement mass is 465 g, or 0.26 g per mm² of the 62×29 mm track envelope — inertia that the drive must accelerate on every index of the cam the 30 mm pin bore falls in the small band, the workhorse size for gearbox planetary positions, hydraulic pumps and general cam and linkage duty PWTR is the sealed double-row full-complement yoke roller: two cylindrical roller rows, 2RS contact seals both sides and the profiled (crowned) running surface on the 62 mm outer ring At 465 g the double-row roller has substantial inertia; the cam drive must accelerate that mass, and a misaligned track concentrates load onto one row As an X-life (-XL) bearing it benefits from the optimised surface finish that reduces friction and raises the fatigue strength behind the 5.9 kN Cur value. 2RS means two side contact seals: the sealed roller excludes contamination without a separate shield arrangement, at the published limiting speed of 2,200 r/min. Typical applications include cam drives and indexing tables, printing press sheet-transfer grippers and woodworking machine feed tracks, where the 62 mm track diameter and 35 kN dynamic rating match the duty. In cam drives and indexing tables the unit fits a compact 30 mm seat, and in printing press sheet-transfer grippers the 465 g mass keeps follower kinetics light. Designers also specify it for woodworking machine feed tracks, relying on the 29 mm width and the published 46 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. 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.

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

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

Frequently asked questions

What are the dimensions of the PWTR30-2RS-XL?

The PWTR30-2RS-XL is a PWTR sealed double-row full-complement yoke-type track roller with 62 mm outside diameter, 30 mm bore and 29 mm width, envelope 30×62×29 mm. Mass is 465 g.

What does the PWTR30-2RS-XL designation mean in the FAG/INA HR1 catalogue?

PWTR30-2RS-XL identifies this PWTR sealed double-row full-complement yoke-type track roller in the Schaeffler HR1 rolling bearings catalogue; the -XL suffix marks the X-life execution. The envelope is 30×62×29 mm and the catalogue ratings are C 35 kN, C0 46 kN, Cur 5.9 kN.

What is the load capacity of the PWTR30-2RS-XL?

The basic dynamic load rating C is 35 kN and the basic static load rating C0 is 46 kN; the fatigue load limit Cur is 5.9 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 PWTR30-2RS-XL?

HR1 lists a limiting speed of 2,200 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 PWTR30-2RS-XL?

The track should be flat, harder than the roller contact and clean; the crowned 62 mm outer surface tolerates only small angular error. The inner ring lets the 30 mm pin run at normal machined tolerance; lateral guidance comes from the adjacent structure on flangeless executions.
