How the KRV-16-PPA model number is decoded

the 16 mm outside diameter runs on the track while the 6 mm stud shank takes the pin or shaft; the 28 mm overall width spreads the Hertzian contact over the outer ring published ratings C 4.73 kN and C0 6.55 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.72 is typical for full-complement cam follower with needle rollers executions fatigue load limit Pu 0.72 kN at 6 mm stud gives a specific load of 0.79 kN per mm; the limiting speed is 4,300 r/min the 28 mm width carries the load at 0.17 kN per mm of roller complement; section height 5.0 mm between stud and track surface determines the outer-ring bending stiffness mass 19 g over a 16x28 mm envelope works out to 0.042 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty the 6 mm stud places this in the smallest catalogue tier — typical for instrument cams, small conveyors and precision linear guides where space is at a premium 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 16 mm OD is finished with a large-radius crown that compensates for minor track misalignment and reduces edge stress concentration typical applications include woodworking machinery feed rollers, cam mechanisms and indexing drives and material handling lift and lower tracks this size is commonly specified for woodworking machinery feed rollers and cam mechanisms and indexing drives, where the 16 mm track diameter and 6 mm stud fit standard cam and rail geometries in material handling lift and lower tracks the 16 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 19 g mass is low enough for rapid indexing cycles the full complement is sensitive to contamination — any particle that enters the raceway can jam the roller pack and score the track 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

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the higher static capacity of the full complement does not raise the fatigue life; the dynamic C rating still limits the L10 life
• the full complement is sensitive to contamination — any particle that enters the raceway can jam the roller pack and score the track
• the absence of a cage increases friction torque; check that the cam drive can overcome the drag at low speed
