How the NUTR1542 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 18.3 kN and C0 24.7 kN for the NUTR double-row full-complement yoke-type track roller; the C/C0 ratio of 0.74 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 3.15 kN at 15 mm bore, equivalent to 1.22 kN of dynamic rating per millimetre — the limiting speed is 6,500 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 0.96 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 with a 15 mm pin bore the 19 mm width and 18.3 kN C rating suit high-cycle industrial machinery rather than instrument duty NUTR is the double-row full-complement yoke roller: two cylindrical roller rows give the highest radial capacity in the 42 mm track-roller envelope, open and relubricatable At 158 g the double-row roller has substantial inertia; the cam drive must accelerate that mass, and a misaligned track concentrates load onto one row Typical applications include packaging machine timing mechanisms, woodworking machine feed tracks and agricultural and textile cam followers, where the 42 mm track diameter and 18.3 kN dynamic rating match the duty. In packaging machine timing mechanisms the unit fits a compact 15 mm seat, and in woodworking machine feed tracks the 158 g mass keeps follower kinetics light. Designers also specify it for agricultural and textile cam followers, relying on the 19 mm width and the published 24.7 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.

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.
