How the KRV-62-PPA model number is decoded

the 62 mm outside diameter runs on the track while the 24 mm stud shank takes the pin or shaft; the 80 mm overall width spreads the Hertzian contact over the outer ring published ratings C 31.4 kN and C0 72 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.44 is typical for full-complement cam follower with needle rollers executions fatigue load limit Pu 9 kN at 24 mm stud gives a specific load of 1.31 kN per mm; the limiting speed is 1,700 r/min the 80 mm width carries the load at 0.39 kN per mm of roller complement; section height 19.0 mm between stud and track surface determines the outer-ring bending stiffness mass 790 g over a 62x80 mm envelope works out to 0.159 g per mm² of projected area — a useful figure when sizing the drive inertia for low-speed cam duty the 24 mm stud diameter falls in the small-size band, the most common choice for general-purpose cam followers and light conveyor transfer rollers KRV denotes the full-complement cam follower: no cage, the maximum number of needle rollers for the 62 mm envelope, raising C0 to 72 kN at the cost of the 1700 r/min speed limit the PPA suffix specifies a crowned (radius) outer-ring running surface instead of the standard cylindrical profile — the crown distributes edge stress when the track is not perfectly aligned typical applications include sheet-metal forming press feeds, textile machine cam drives and agricultural equipment cam followers this size is commonly specified for sheet-metal forming press feeds and textile machine cam drives, where the 62 mm track diameter and 24 mm stud fit standard cam and rail geometries in agricultural equipment cam followers the 62 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 790 g mass is low enough for rapid indexing cycles 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 full complement is sensitive to contamination — any particle that enters the raceway can jam the roller pack and score the track

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
• 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 higher static capacity of the full complement does not raise the fatigue life; the dynamic C rating still limits the L10 life
