How the NATV-5 model number is decoded

the 16 mm outside diameter runs on the track while the 5 mm bore takes the pin or shaft; the 12 mm overall width spreads the Hertzian contact over the outer ring published ratings C 4.73 kN and C0 6.55 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.72 is typical for full-complement support roller with flange rings, with inner ring executions fatigue load limit Pu 0.72 kN at 5 mm bore gives a specific load of 0.95 kN per mm; the limiting speed is 4,300 r/min the 12 mm width carries the load at 0.39 kN per mm of roller complement; section height 5.5 mm between bore and track surface determines the outer-ring bending stiffness mass 15 g over a 16x12 mm envelope works out to 0.078 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty the 5 mm bore places this in the smallest catalogue tier — typical for instrument cams, small conveyors and precision linear guides where space is at a premium reading NATV: cageless, fully rolled needle roller support roller; the extra rollers raise C0 to 6.55 kN for slow, heavy cam duty typical applications include linear guide and track systems, robotic arm track guidance and paper mill web guide rollers this size is commonly specified for linear guide and track systems and robotic arm track guidance, where the 16 mm track diameter and 5 mm bore fit standard cam and rail geometries in paper mill web guide rollers the 16 mm outer ring provides the rolling contact while the inner ring bore simplifies mounting; the 15 g mass is low enough for rapid indexing cycles full-complement rollers generate more friction and heat — the lower limiting speed is a hard thermal limit, not a suggestion without a cage the rollers can skew under momentary unloading, leading to edge loading and premature raceway pitting

Selection pitfalls — read before you substitute

• without a cage the rollers can skew under momentary unloading, leading to edge loading and premature raceway pitting
• full-complement rollers generate more friction and heat — the lower limiting speed is a hard thermal limit, not a suggestion
• the higher static capacity invites overloading; remember the dynamic C rating still governs fatigue life
