How the PWTR-30-2RS model number is decoded

the 62 mm outside diameter runs on the track while the 30 mm bore takes the pin or shaft; the 29 mm overall width spreads the Hertzian contact over the outer ring published ratings C 31.9 kN and C0 32.5 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 0.98 is typical for sealed double-row full-complement support roller with integral flanges executions fatigue load limit Pu 4.05 kN at 30 mm bore gives a specific load of 1.06 kN per mm; the limiting speed is 2,600 r/min the 29 mm width carries the load at 1.10 kN per mm of roller complement; section height 16.0 mm between bore and track surface determines the outer-ring bending stiffness mass 470 g over a 62x29 mm envelope works out to 0.261 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty the 30 mm bore places this in the medium band, where cylindrical-roller full-complement designs become available for heavier radial loads the PWTR..2RS execution combines the maximum load capacity of the double-row full complement with integral sealing — the heaviest and most protected option in the support roller range typical applications include automatic assembly machine linkages, food processing line track rollers and printing press roller followers this size is commonly specified for automatic assembly machine linkages and food processing line track rollers, where the 62 mm track diameter and 30 mm bore fit standard cam and rail geometries in printing press roller followers the 62 mm outer ring provides the rolling contact while the inner ring bore simplifies mounting; the 470 g mass is low enough for rapid indexing cycles the integral flanges and seals add width; verify the track channel accommodates the full B dimension plus flange protrusion sealed full-complement rollers are the heaviest option — check that the drive can accelerate the mass at the required cam rate

Selection pitfalls — read before you substitute

• the 2RS seals protect the roller rows but limit relubrication options; the unit is effectively sealed for life
• the integral flanges and seals add width; verify the track channel accommodates the full B dimension plus flange protrusion
• sealed full-complement rollers are the heaviest option — check that the drive can accelerate the mass at the required cam rate
