How the NUKR-35-A model number is decoded

the 35 mm outside diameter runs on the track while the 16 mm stud shank takes the pin or shaft; the 52 mm overall width spreads the Hertzian contact over the outer ring published ratings C 16.8 kN and C0 17.6 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.95 is typical for full-complement cylindrical-roller cam follower executions fatigue load limit Pu 2 kN at 16 mm stud gives a specific load of 1.05 kN per mm; the limiting speed is 5,000 r/min the 52 mm width carries the load at 0.32 kN per mm of roller complement; section height 9.5 mm between stud and track surface determines the outer-ring bending stiffness mass 160 g over a 35x52 mm envelope works out to 0.088 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-high-speed cam duty at 16 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 food processing line track rollers, printing press roller followers and automotive welding jig positioners this size is commonly specified for food processing line track rollers and printing press roller followers, where the 35 mm track diameter and 16 mm stud fit standard cam and rail geometries in automotive welding jig positioners the 35 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 160 g mass is low enough for rapid indexing cycles the two cylindrical roller rows share the outer ring bending load; a misaligned track concentrates the load on one row and halves the life the stud head and pressed-on flange ring provide the only axial guidance — side thrust from a helical cam can dislodge the flange

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
• the two cylindrical roller rows share the outer ring bending load; a misaligned track concentrates the load on one row and halves the life
• full-complement cylindrical rollers are stiff but unforgiving: any shaft deflection directly increases edge stress
