How the KRE-62-PPA model number is decoded

the 62 mm outside diameter runs on the track while the 28 mm stud shank takes the pin or shaft; the 80 mm overall width spreads the Hertzian contact over the outer ring published ratings C 24.6 kN and C0 44 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.56 is typical for cam follower with eccentric collar executions fatigue load limit Pu 5.5 kN at 28 mm stud gives a specific load of 0.88 kN per mm; the limiting speed is 2,400 r/min the 80 mm width carries the load at 0.31 kN per mm of roller complement; section height 17.0 mm between stud and track surface determines the outer-ring bending stiffness mass 800 g over a 62x80 mm envelope works out to 0.161 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty with a 28 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 reading KRE: cam follower with eccentric adjustment collar; the collar seat on the 28 mm stud is offset so a spanner turn re-centres the roller on the cam reading the PPA suffix: crowned outer ring — the track contact is barrel-shaped to tolerate angular misalignment between the roller axis and the track 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 62 mm track diameter and 28 mm stud fit standard cam and rail geometries in material handling lift and lower tracks the 62 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 800 g mass is low enough for rapid indexing cycles do not use the eccentric collar to compensate for gross track misalignment; the adjustment range is typically only 0.5–1.0 mm mark the collar position before disassembly; reassembly without the original setting loses the preload calibration

Typical equipment & failure modes

Common applications

  • packaging machine timing cams
  • woodworking machinery feed rollers
  • glass processing line conveyors
  • linear guide and track systems

Known failure patterns

  • the eccentric collar is a friction fit on the stud — do not hammer it; use the correct spanner to rotate it to the preload setting
  • after adjusting the eccentric collar, re-torque the stud nut; the collar setting changes the stud engagement length
  • the eccentric adjustment range is limited; if the required offset exceeds the collar throw, the bracket must be re-machined
  • the eccentric collar is a friction fit — excessive adjustment force can score the stud surface and create a stress concentration
  • do not use the eccentric collar to compensate for gross track misalignment; the adjustment range is typically only 0.5–1.0 mm
  • mark the collar position before disassembly; reassembly without the original setting loses the preload calibration

Selection pitfalls — read before you substitute

  • mark the collar position before disassembly; reassembly without the original setting loses the preload calibration
  • do not use the eccentric collar to compensate for gross track misalignment; the adjustment range is typically only 0.5–1.0 mm
  • the eccentric collar is a friction fit on the stud — do not hammer it; use the correct spanner to rotate it to the preload setting

Frequently asked questions

What are the dimensions of the KRE-62-PPA?

KRE-62-PPA is a cam follower with eccentric collar with 62 mm outside diameter, 28 mm stud shank diameter and 80 mm overall width. The stud is 28 mm and the track contact diameter is 62 mm.

What does the KRE designation mean?

The KRE prefix identifies this as a cam follower with eccentric collar. In the SKF catalogue this designation carries the full specification including the 62x28x80 mm envelope and the 2400 r/min limiting speed.

What is the load capacity of KRE-62-PPA?

The published basic dynamic load rating C is 24.6 kN and the basic static load rating C0 is 44 kN. These values already include the bending-stress correction for the thick-walled outer ring running on a track.
