How the NUTR2562 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 35.5 kN and C0 54 kN for the NUTR double-row full-complement yoke-type track roller; the C/C0 ratio of 0.66 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 7 kN at 25 mm bore, equivalent to 1.42 kN of dynamic rating per millimetre — the limiting speed is 4,200 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 1.42 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 at 25 mm pin bore this size balances the 62 mm outside diameter against machineability of the adjacent parts — the most frequently specified band in the HR1 range Two roller rows across the 25 mm width provide C 35.5 kN and C0 54 kN, with the thick outer ring profiled to tolerate track misalignment The open form is relubricated via the inner ring; follow the interval strictly because the packed roller rows trap contaminants Typical applications include robotic arm linear axes, agricultural and textile cam followers and conveyor transfer and diverting stations, where the 62 mm track diameter and 35.5 kN dynamic rating match the duty. In robotic arm linear axes the unit fits a compact 25 mm seat, and in agricultural and textile cam followers the 450 g mass keeps follower kinetics light. Designers also specify it for conveyor transfer and diverting stations, relying on the 25 mm width and the published 54 kN static rating. 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. Check the mating track hardness and flatness — a soft or scalloped rail fails before the 62 mm outer ring does.

Selection pitfalls — read before you substitute

• 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.
• Check the mating track hardness and flatness — a soft or scalloped rail fails before the 62 mm outer ring does.
• 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.
