How the PWTR1542-2RS-XL model number is decoded

envelope 15×42×19 mm: the 42 mm outside diameter is the track-running surface — a thick-walled outer ring over a 15 mm bore — and the 19 mm width sets the contact width on the mating track the catalogue lists C 14.7 kN and C0 16.2 kN for the PWTR sealed double-row full-complement yoke-type track roller; the C/C0 ratio of 0.91 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 2.18 kN at 15 mm bore, equivalent to 0.98 kN of dynamic rating per millimetre — the limiting speed is 6,000 r/min and, as for HR1 track rollers, no thermal reference speed is published the 15 mm bore takes the mounting pin or shaft; across the 19 mm contact width the dynamic rating works out to 0.77 kN per millimetre of rolling-element complement mass is 158 g, or 0.20 g per mm² of the 42×19 mm track envelope — inertia that the drive must accelerate on every index of the cam the 15 mm pin bore falls in the small band, the workhorse size for gearbox planetary positions, hydraulic pumps and general cam and linkage duty The 15 mm bore takes the pin; yoke design means the machine lugs support the roller on both sides, which is essential given the 16.2 kN static rating Reading NUTR/PWTR: double-row, no cage, cylindrical rollers rather than needles — the pack is built for shock-dominated heavy track duty at 6,000 r/min X-life status (-XL) indicates the current Schaeffler premium execution at 15 mm bore; the 16.2 kN C0 rating reflects the improved rolling-contact geometry. Reading the suffix: 2RS is the FAG/INA code for rubbing lip seals at both faces, making the 15 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 42 mm track diameter and 14.7 kN dynamic rating match the duty. In conveyor transfer and diverting stations the unit fits a compact 15 mm seat, and in robotic arm linear axes the 158 g mass keeps follower kinetics light. Designers also specify it for automotive welding jig rollers, relying on the 19 mm width and the published 16.2 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. Flangeless STO/RSTO/RNA22/NA22 rollers need external axial location; circlips or shoulders must control end float or the roller walks off the track.

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.
• Flangeless STO/RSTO/RNA22/NA22 rollers need external axial location; circlips or shoulders must control end float or the roller walks off the track.
• Sealed PP/2RSR units are greased for life: never add a grease nipple, and respect the lower limiting speed imposed by the rubbing lips.
