How the NUKR-62-A model number is decoded

the 62 mm outside diameter runs on the track while the 24 mm stud shank takes the pin or shaft; the 80 mm overall width spreads the Hertzian contact over the outer ring published ratings C 41.3 kN and C0 48 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.86 is typical for full-complement cylindrical-roller cam follower executions fatigue load limit Pu 5.85 kN at 24 mm stud gives a specific load of 1.72 kN per mm; the limiting speed is 2,600 r/min the 80 mm width carries the load at 0.52 kN per mm of roller complement; section height 19.0 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 at 24 mm stud this size balances load capacity and envelope compactness — a frequent pick for packaging machines and printing press linkages NUKR is the heavy-duty stud-type track roller: two full rows of cylindrical rollers without cage give the highest dynamic capacity of the cam follower range typical applications include textile machine cam drives, agricultural equipment cam followers and packaging machine timing cams this size is commonly specified for textile machine cam drives and agricultural equipment cam followers, where the 62 mm track diameter and 24 mm stud fit standard cam and rail geometries in packaging machine timing cams 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 full-complement cylindrical rollers are stiff but unforgiving: any shaft deflection directly increases edge stress the twin-row construction is the widest cam follower option; verify the track channel width accommodates the full B dimension

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the stud head and pressed-on flange ring provide the only axial guidance — side thrust from a helical cam can dislodge the flange
• full-complement cylindrical rollers are stiff but unforgiving: any shaft deflection directly increases edge stress
• the twin-row construction is the widest cam follower option; verify the track channel width accommodates the full B dimension
