How the KRV-22-PPA model number is decoded

the 22 mm outside diameter runs on the track while the 10 mm stud shank takes the pin or shaft; the 36 mm overall width spreads the Hertzian contact over the outer ring published ratings C 6.05 kN and C0 9.15 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.66 is typical for full-complement cam follower with needle rollers executions fatigue load limit Pu 1.04 kN at 10 mm stud gives a specific load of 0.60 kN per mm; the limiting speed is 3,600 r/min the 36 mm width carries the load at 0.17 kN per mm of roller complement; section height 6.0 mm between stud and track surface determines the outer-ring bending stiffness mass 45 g over a 22x36 mm envelope works out to 0.057 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty at 10 mm stud diameter this sits in the miniature band of the range, where the compact envelope suits tight cam tracks and light-duty indexing mechanisms the KRV prefix means a cageless needle roller cam follower — more rollers, higher static capacity, and a reduced limiting speed for slow, heavily loaded cams PPA denotes the crowned running surface: the 22 mm OD is ground to a large radius rather than straight, reducing edge loading on misaligned cam tracks typical applications include glass processing line conveyors, linear guide and track systems and robotic arm track guidance this size is commonly specified for glass processing line conveyors and linear guide and track systems, where the 22 mm track diameter and 10 mm stud fit standard cam and rail geometries in robotic arm track guidance the 22 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 45 g mass is low enough for rapid indexing cycles the higher static capacity of the full complement does not raise the fatigue life; the dynamic C rating still limits the L10 life 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 needle rollers have no cage to separate them — momentary unloading can let rollers skew and jam in the track
• the higher static capacity of the full complement does not raise the fatigue life; the dynamic C rating still limits the L10 life
• the absence of a cage increases friction torque; check that the cam drive can overcome the drag at low speed
