How the KRV-35-PPA model number is decoded

the 35 mm outside diameter runs on the track while the 16 mm stud shank takes the pin or shaft; the 52 mm overall width spreads the Hertzian contact over the outer ring published ratings C 12.3 kN and C0 23.2 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.53 is typical for full-complement cam follower with needle rollers executions fatigue load limit Pu 2.7 kN at 16 mm stud gives a specific load of 0.77 kN per mm; the limiting speed is 2,600 r/min the 52 mm width carries the load at 0.24 kN per mm of roller complement; section height 9.5 mm between stud and track surface determines the outer-ring bending stiffness mass 170 g over a 35x52 mm envelope works out to 0.093 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty the 16 mm stud shank puts this in the small-to-medium transition where the roller complement is still needle-type but the outer ring is thick enough for moderate shock loads 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 35 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 35 mm track diameter and 16 mm stud fit standard cam and rail geometries in robotic arm track guidance the 35 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 170 g mass is low enough for rapid indexing cycles the heavy roller pack and full complement make this the highest-inertia cam follower; verify the drive can accelerate the mass at the required cam rate full-complement needle rollers have no cage to separate them — momentary unloading can let rollers skew and jam in the track

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the absence of a cage increases friction torque; check that the cam drive can overcome the drag at low speed
• the heavy roller pack and full complement make this the highest-inertia cam follower; verify the drive can accelerate the mass at the required cam rate
• 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
