How the KRV-80-PPA model number is decoded

the 80 mm outside diameter runs on the track while the 30 mm stud shank takes the pin or shaft; the 100 mm overall width spreads the Hertzian contact over the outer ring published ratings C 45.7 kN and C0 114 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.40 is typical for full-complement cam follower with needle rollers executions fatigue load limit Pu 14 kN at 30 mm stud gives a specific load of 1.52 kN per mm; the limiting speed is 1,400 r/min the 100 mm width carries the load at 0.46 kN per mm of roller complement; section height 25.0 mm between stud and track surface determines the outer-ring bending stiffness mass 1650 g over a 80x100 mm envelope works out to 0.206 g per mm² of projected area — a useful figure when sizing the drive inertia for low-speed cam duty with a 30 mm stud shank this is a medium-size track roller — the envelope is large enough for sealed, greased-for-life executions without sacrificing dynamic capacity the KRV execution is the heavy-static counterpart of KR: full complement of needle rollers for maximum load capacity in slow or oscillating cam tracks the PPA variant has a crowned track surface: the 80 mm OD is finished with a large-radius crown that compensates for minor track misalignment and reduces edge stress concentration 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 80 mm track diameter and 30 mm stud fit standard cam and rail geometries in agricultural equipment cam followers the 80 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 1650 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
