How the PWKR-62-2RS model number is decoded

the 62 mm outside diameter runs on the track while the 24 mm stud shank takes the pin or shaft; the 80 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 full-complement cylindrical-roller cam follower executions fatigue load limit Pu 4.05 kN at 24 mm stud gives a specific load of 1.33 kN per mm; the limiting speed is 2,600 r/min the 80 mm width carries the load at 0.40 kN per mm of roller complement; section height 19.0 mm between stud and track surface determines the outer-ring bending stiffness mass 800 g over a 62x80 mm envelope works out to 0.161 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-speed cam duty the 24 mm stud diameter falls in the small-size band, the most common choice for general-purpose cam followers and light conveyor transfer rollers the PWKR..2RS execution combines the maximum load capacity of the double-row full complement with integral sealing — the heaviest and most protected option in the cam follower range typical applications include cam mechanisms and indexing drives, material handling lift and lower tracks and sheet-metal forming press feeds this size is commonly specified for cam mechanisms and indexing drives and material handling lift and lower tracks, where the 62 mm track diameter and 24 mm stud fit standard cam and rail geometries in sheet-metal forming press feeds the 62 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 800 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 sealed twin-row construction is the heaviest cam follower option — verify the drive torque can accelerate the roller at the required cam profile rate
• 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
