How the NUKRE-90-A model number is decoded

the 90 mm outside diameter runs on the track while the 35 mm stud shank takes the pin or shaft; the 100 mm overall width spreads the Hertzian contact over the outer ring published ratings C 78.1 kN and C0 102 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.77 is typical for full-complement cylindrical-roller cam follower with eccentric collar executions fatigue load limit Pu 12.7 kN at 35 mm stud gives a specific load of 2.23 kN per mm; the limiting speed is 1,900 r/min the 100 mm width carries the load at 0.78 kN per mm of roller complement; section height 27.5 mm between stud and track surface determines the outer-ring bending stiffness mass 2000 g over a 90x100 mm envelope works out to 0.222 g per mm² of projected area — a useful figure when sizing the drive inertia for low-speed cam duty at 35 mm stud this size crosses into the range where double-row full-complement executions (NUTR/PWTR/NUKR) offer substantially higher C ratings than the single-row needle designs 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 the NUKRE designation adds on-machine adjustability to the heavy twin-row cylindrical roller cam follower — the eccentric collar compensates for track wear and mounting tolerances 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 90 mm track diameter and 35 mm stud fit standard cam and rail geometries in material handling lift and lower tracks the 90 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 2000 g mass is low enough for rapid indexing cycles without integral flanges, axial float must be controlled by external washers or circlips — free axial movement causes edge loading on the outer ring the needle roller complement is sensitive to misalignment; a bent shaft or angled track creates uneven load distribution and early raceway pitting

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the open design has no integral sealing; in dusty environments contamination enters directly between the needle rollers and the raceway
• without integral flanges, axial float must be controlled by external washers or circlips — free axial movement causes edge loading on the outer ring
• mounting on a worn or undersized pin reduces the effective clearance and can preload the roller hot
