How the NA-2202-2RS model number is decoded

the 35 mm outside diameter runs on the track while the 15 mm bore takes the pin or shaft; the 14 mm overall width spreads the Hertzian contact over the outer ring published ratings C 7.48 kN and C0 9.3 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.80 is typical for sealed support roller without flange rings, with inner ring executions fatigue load limit Pu 1.12 kN at 15 mm bore gives a specific load of 0.50 kN per mm; the limiting speed is 5,000 r/min the 14 mm width carries the load at 0.53 kN per mm of roller complement; section height 10.0 mm between bore and track surface determines the outer-ring bending stiffness mass 75 g over a 35x14 mm envelope works out to 0.153 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-high-speed cam duty the 15 mm bore puts this in the small-to-medium transition where the roller complement is still needle-type but the outer ring is thick enough for moderate shock loads the NA 22 series with 2RS suffix denotes a compact sealed support roller for applications where relubrication access is impossible and the track environment carries dust or moisture 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 35 mm track diameter and 15 mm bore fit standard cam and rail geometries in material handling lift and lower tracks the 35 mm outer ring provides the rolling contact while the inner ring bore simplifies mounting; the 75 g mass is low enough for rapid indexing cycles NBR seals degrade in contact with certain synthetic lubricants and solvents; verify compatibility before exposing the roller to process chemicals the compact envelope and sealed construction make this size sensitive to over-greasing during manufacture — excess grease churns and overheats at speed

Selection pitfalls — read before you substitute

• the compact envelope and sealed construction make this size sensitive to over-greasing during manufacture — excess grease churns and overheats at speed
• NBR seals degrade in contact with certain synthetic lubricants and solvents; verify compatibility before exposing the roller to process chemicals
• the 2RS seals limit the maximum speed; exceeding the printed limiting speed overheats the NBR lips and destroys the grease fill
