How the KRV-26-PPA model number is decoded
the 26 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 6.82 kN and C0 11 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.62 is typical for full-complement cam follower with needle rollers executions fatigue load limit Pu 1.25 kN at 10 mm stud gives a specific load of 0.68 kN per mm; the limiting speed is 3,600 r/min the 36 mm width carries the load at 0.19 kN per mm of roller complement; section height 8.0 mm between stud and track surface determines the outer-ring bending stiffness mass 59 g over a 26x36 mm envelope works out to 0.063 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty the 10 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 KRV removes the cage to maximise the needle roller count in the 26 mm envelope; the result is the highest static capacity of the stud-type needle cam followers, with a corresponding drop in permissible speed PPA changes the outer-ring profile from cylindrical to crowned; the barrel shape lowers edge stress when the cam track is not perfectly parallel to the roller axis 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 26 mm track diameter and 10 mm stud fit standard cam and rail geometries in agricultural equipment cam followers the 26 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 59 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
Common applications
- agricultural equipment cam followers
- sheet-metal forming press feeds
- packaging machine timing cams
- glass processing line conveyors
Known failure patterns
- 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
- 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
- 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
Selection pitfalls — read before you substitute

Frequently asked questions
What are the dimensions of the KRV-26-PPA?
KRV-26-PPA is a full-complement cam follower with needle rollers with 26 mm outside diameter, 10 mm stud shank diameter and 36 mm overall width. The stud is 10 mm and the track contact diameter is 26 mm.
What does the KRV designation mean?
The KRV prefix identifies this as a full-complement cam follower with needle rollers. In the SKF catalogue this designation carries the full specification including the 26x10x36 mm envelope and the 3600 r/min limiting speed.
What is the load capacity of KRV-26-PPA?
The published basic dynamic load rating C is 6.82 kN and the basic static load rating C0 is 11 kN. These values already include the bending-stress correction for the thick-walled outer ring running on a track.
