How the PWTR2562-2RS-XL model number is decoded

envelope 25×62×25 mm: the 62 mm outside diameter is the track-running surface — a thick-walled outer ring over a 25 mm bore — and the 25 mm width sets the contact width on the mating track the catalogue lists C 30 kN and C0 42.5 kN for the PWTR sealed double-row full-complement yoke-type track roller; the C/C0 ratio of 0.71 reflects a rolling-element pack sized for heavy static track loading, and the 18.5 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 5.3 kN at 25 mm bore, equivalent to 1.20 kN of dynamic rating per millimetre — the limiting speed is 3,800 r/min and, as for HR1 track rollers, no thermal reference speed is published the 25 mm bore takes the mounting pin or shaft; across the 25 mm contact width the dynamic rating works out to 1.20 kN per millimetre of rolling-element complement mass is 450 g, or 0.29 g per mm² of the 62×25 mm track envelope — inertia that the drive must accelerate on every index of the cam with a 25 mm pin bore the 25 mm width and 30 kN C rating suit high-cycle industrial machinery rather than instrument duty The 2RS seals make the unit greased for life: use it where wash-down, dust or lack of access rules out relubrication The 25 mm bore takes the pin; yoke design means the machine lugs support the roller on both sides, which is essential given the 42.5 kN static rating The -XL suffix is the Schaeffler X-life mark: interchangeable envelope with the basic bearing, but higher load capacity and lower running temperature at the 3,800 r/min limit. The sealed 2RS 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 glass and ceramic line conveyors, linear rail and profile track guidance and printing press sheet-transfer grippers, where the 62 mm track diameter and 30 kN dynamic rating match the duty. In glass and ceramic line conveyors the unit fits a compact 25 mm seat, and in linear rail and profile track guidance the 450 g mass keeps follower kinetics light. Designers also specify it for printing press sheet-transfer grippers, relying on the 25 mm width and the published 42.5 kN static rating. Flangeless STO/RSTO/RNA22/NA22 rollers need external axial location; circlips or shoulders must control end float or the roller walks off the track. 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.

Selection pitfalls — read before you substitute

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