How the NUTR-50110-A model number is decoded

the 110 mm outside diameter runs on the track while the 50 mm bore takes the pin or shaft; the 32 mm overall width spreads the Hertzian contact over the outer ring published ratings C 78.1 kN and C0 116 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.67 is typical for double-row full-complement support roller, no integral flange executions fatigue load limit Pu 14.3 kN at 50 mm bore gives a specific load of 1.56 kN per mm; the limiting speed is 1,600 r/min the 32 mm width carries the load at 2.44 kN per mm of roller complement; section height 30.0 mm between bore and track surface determines the outer-ring bending stiffness mass 1700 g over a 110x32 mm envelope works out to 0.483 g per mm² of projected area — a useful figure when sizing the drive inertia for low-speed cam duty with a 50 mm bore this is a medium-size track roller — the envelope is large enough for sealed, greased-for-life executions without sacrificing dynamic capacity NUTR is the heavy-duty support roller: two full rows of cylindrical rollers without a cage give the maximum dynamic capacity for the 110 mm envelope, but the outer ring relies entirely on the pressed-on flanges for axial location the A suffix denotes the improved design: optimised internal geometry and surface finish raise the limiting speed and reduce friction compared with the earlier execution 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 110 mm track diameter and 50 mm bore fit standard cam and rail geometries in packaging machine timing cams the 110 mm outer ring provides the rolling contact while the inner ring bore simplifies mounting; the 1700 g mass is low enough for rapid indexing cycles relubrication is difficult because the roller rows are packed; follow the greasing interval strictly the two roller rows share the outer ring bending load; a misaligned track concentrates the load on one row and halves the life

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the double-row construction is the widest in the support roller range; verify the track channel width accommodates the full B dimension
• relubrication is difficult because the roller rows are packed; follow the greasing interval strictly
• the outer ring has no integral flange between the two roller rows — axial guidance depends entirely on the pressed-on flange rings, which can shift under heavy side load
