How the KRE-19-PPA model number is decoded

the 19 mm outside diameter runs on the track while the 11 mm stud shank takes the pin or shaft; the 32 mm overall width spreads the Hertzian contact over the outer ring published ratings C 3.47 kN and C0 3.8 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.91 is typical for cam follower with eccentric collar executions fatigue load limit Pu 0.415 kN at 11 mm stud gives a specific load of 0.32 kN per mm; the limiting speed is 5,600 r/min the 32 mm width carries the load at 0.11 kN per mm of roller complement; section height 4.0 mm between stud and track surface determines the outer-ring bending stiffness mass 32 g over a 19x32 mm envelope works out to 0.053 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-high-speed cam duty at 11 mm stud this size balances load capacity and envelope compactness — a frequent pick for packaging machines and printing press linkages reading KRE: cam follower with eccentric adjustment collar; the collar seat on the 11 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 material handling lift and lower tracks, sheet-metal forming press feeds and textile machine cam drives this size is commonly specified for material handling lift and lower tracks and sheet-metal forming press feeds, where the 19 mm track diameter and 11 mm stud fit standard cam and rail geometries in textile machine cam drives the 19 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 32 g mass is low enough for rapid indexing cycles 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

Selection pitfalls — read before you substitute

• 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
