How the PWTR-15-2RS model number is decoded

the 35 mm outside diameter runs on the track while the 15 mm bore takes the pin or shaft; the 19 mm overall width spreads the Hertzian contact over the outer ring published ratings C 11.9 kN and C0 11.4 kN already include the bending-stress correction for the unsupported outer ring — the C/C0 ratio of 1.04 is typical for sealed double-row full-complement support roller with integral flanges executions fatigue load limit Pu 1.2 kN at 15 mm bore gives a specific load of 0.79 kN per mm; the limiting speed is 5,000 r/min the 19 mm width carries the load at 0.63 kN per mm of roller complement; section height 10.0 mm between bore and track surface determines the outer-ring bending stiffness mass 99 g over a 35x19 mm envelope works out to 0.149 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-high-speed cam duty at 15 mm bore this size balances load capacity and envelope compactness — a frequent pick for packaging machines and printing press linkages 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 paper mill web guide rollers, automatic assembly machine linkages and food processing line track rollers this size is commonly specified for paper mill web guide rollers and automatic assembly machine linkages, where the 35 mm track diameter and 15 mm bore fit standard cam and rail geometries in food processing line track rollers the 35 mm outer ring provides the rolling contact while the inner ring bore simplifies mounting; the 99 g mass is low enough for rapid indexing cycles the 2RS seals limit relubrication; the grease fill must last the design life of the cam mechanism the sealed outer ring cannot be inspected without destroying the seals; plan replacement on a time or cycle basis rather than condition monitoring

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the integral flanges and seals add width; verify the track channel accommodates the full B dimension plus flange protrusion
• the 2RS seals limit relubrication; the grease fill must last the design life of the cam mechanism
• sealed full-complement rollers are the heaviest option — check that the drive can accelerate the mass at the required cam rate
