How the NATV-10-PPA model number is decoded

the 30 mm outside diameter runs on the track while the 10 mm bore takes the pin or shaft; the 15 mm overall width spreads the Hertzian contact over the outer ring published ratings C 8.97 kN and C0 14.6 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.61 is typical for full-complement support roller with flange rings, with inner ring executions fatigue load limit Pu 1.66 kN at 10 mm bore gives a specific load of 0.90 kN per mm; the limiting speed is 3,200 r/min the 15 mm width carries the load at 0.60 kN per mm of roller complement; section height 10.0 mm between bore and track surface determines the outer-ring bending stiffness mass 64 g over a 30x15 mm envelope works out to 0.142 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty with a 10 mm bore this is one of the smallest sizes listed; the reduced section height limits the outer-ring bending stiffness, so track alignment must be held closely the NATV designation means full complement of needle rollers with flange rings — maximum load capacity in the 30 mm envelope, traded against the reduced 3200 r/min speed limit PPA denotes the crowned running surface: the 30 mm OD is ground to a large radius rather than straight, reducing edge loading on misaligned cam tracks typical applications include food processing line track rollers, printing press roller followers and automotive welding jig positioners this size is commonly specified for food processing line track rollers and printing press roller followers, where the 30 mm track diameter and 10 mm bore fit standard cam and rail geometries in automotive welding jig positioners the 30 mm outer ring provides the rolling contact while the inner ring bore simplifies mounting; the 64 g mass is low enough for rapid indexing cycles the absence of a cage increases friction torque; check that the cam drive can overcome the drag at low speed in oscillating applications the rollers can brinell if the stroke is too short to rotate the full complement; ensure the motion profile rotates the rollers through at least one full revolution

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• in oscillating applications the rollers can brinell if the stroke is too short to rotate the full complement; ensure the motion profile rotates the rollers through at least one full revolution
• the absence of a cage increases friction torque; check that the cam drive can overcome the drag at low speed
• full-complement rollers generate more friction and heat — the lower limiting speed is a hard thermal limit, not a suggestion
