How the NATV-8 model number is decoded

the 24 mm outside diameter runs on the track while the 8 mm bore takes the pin or shaft; the 15 mm overall width spreads the Hertzian contact over the outer ring published ratings C 7.48 kN and C0 11.4 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.66 is typical for full-complement support roller with flange rings, with inner ring executions fatigue load limit Pu 1.32 kN at 8 mm bore gives a specific load of 0.94 kN per mm; the limiting speed is 3,600 r/min the 15 mm width carries the load at 0.50 kN per mm of roller complement; section height 8.0 mm between bore and track surface determines the outer-ring bending stiffness mass 42 g over a 24x15 mm envelope works out to 0.117 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty at 8 mm bore this sits in the miniature band of the range, where the compact envelope suits tight cam tracks and light-duty indexing mechanisms reading NATV: cageless, fully rolled needle roller support roller; the extra rollers raise C0 to 11.4 kN for slow, heavy cam duty typical applications include conveyor transfer and diverting rollers, woodworking machinery feed rollers and cam mechanisms and indexing drives this size is commonly specified for conveyor transfer and diverting rollers and woodworking machinery feed rollers, where the 24 mm track diameter and 8 mm bore fit standard cam and rail geometries in cam mechanisms and indexing drives the 24 mm outer ring provides the rolling contact while the inner ring bore simplifies mounting; the 42 g mass is low enough for rapid indexing cycles full complement needle rollers have no cage to separate them — momentary unloading can let rollers skew and jam in the track the absence of a cage increases friction torque; check that the cam drive can overcome the drag at low speed

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• full-complement rollers generate more friction and heat — the lower limiting speed is a hard thermal limit, not a suggestion
• full complement needle rollers have no cage to separate them — momentary unloading can let rollers skew and jam in the track
• without a cage the rollers can skew under momentary unloading, leading to edge loading and premature raceway pitting
