How the NUTR30 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 40.5 kN and C0 55 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 16.0 mm radial section gives the outer ring its bending stiffness fatigue load limit Cur is 7.4 kN at 30 mm bore, equivalent to 1.35 kN of dynamic rating per millimetre — the limiting speed is 2,600 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 1.40 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 Two roller rows across the 29 mm width provide C 40.5 kN and C0 55 kN, with the thick outer ring profiled to tolerate track misalignment Reading NUTR/PWTR: double-row, no cage, cylindrical rollers rather than needles — the pack is built for shock-dominated heavy track duty at 2,600 r/min Typical applications include packaging machine timing mechanisms, woodworking machine feed tracks and agricultural and textile cam followers, where the 62 mm track diameter and 40.5 kN dynamic rating match the duty. In packaging machine timing mechanisms the unit fits a compact 30 mm seat, and in woodworking machine feed tracks the 465 g mass keeps follower kinetics light. Designers also specify it for agricultural and textile cam followers, relying on the 29 mm width and the published 55 kN static rating. Yoke lugs must support the pin on both sides over its full length — single-sided support turns the pin into a cantilever beam. Check the mating track hardness and flatness — a soft or scalloped rail fails before the 62 mm outer ring does.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Yoke lugs must support the pin on both sides over its full length — single-sided support turns the pin into a cantilever beam.
• Check the mating track hardness and flatness — a soft or scalloped rail fails before the 62 mm outer ring does.
• Sealed PP/2RSR units are greased for life: never add a grease nipple, and respect the lower limiting speed imposed by the rubbing lips.
