How the NUKRE-62-A 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 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 with eccentric collar executions fatigue load limit Pu 5.85 kN at 28 mm stud gives a specific load of 1.47 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 17.0 mm between stud and track surface determines the outer-ring bending stiffness mass 820 g over a 62x80 mm envelope works out to 0.165 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 the NUKR designation marks the twin-row cylindrical roller cam follower — the catalogue choice for the heaviest radial loads and shock-dominated cam duty NUKRE provides the same heavy-section twin-row capacity as NUKR with the added benefit of radial adjustment via the eccentric collar on the stud typical applications include printing press roller followers, automotive welding jig positioners and conveyor transfer and diverting rollers this size is commonly specified for printing press roller followers and automotive welding jig positioners, where the 62 mm track diameter and 28 mm stud fit standard cam and rail geometries in conveyor transfer and diverting rollers the 62 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 820 g mass is low enough for rapid indexing cycles the needle roller complement is sensitive to misalignment; a bent shaft or angled track creates uneven load distribution and early raceway pitting without flange rings the roller needs lateral guidance from the housing shoulders — running without side support lets the roller walk off the track

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• mounting on a worn or undersized pin reduces the effective clearance and can preload the roller hot
• the needle roller complement is sensitive to misalignment; a bent shaft or angled track creates uneven load distribution and early raceway pitting
• the narrow width concentrates the Hertzian contact stress; verify the track material hardness is sufficient for the calculated contact pressure
