How the PWKR-35-2RS model number is decoded
the 35 mm outside diameter runs on the track while the 16 mm stud shank takes the pin or shaft; the 52 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 full-complement cylindrical-roller cam follower executions fatigue load limit Pu 1.2 kN at 16 mm stud gives a specific load of 0.74 kN per mm; the limiting speed is 5,000 r/min the 52 mm width carries the load at 0.23 kN per mm of roller complement; section height 9.5 mm between stud and track surface determines the outer-ring bending stiffness mass 160 g over a 35x52 mm envelope works out to 0.088 g per mm² of projected area — a useful figure when sizing the drive inertia for medium-high-speed cam duty at 16 mm stud this size balances load capacity and envelope compactness — a frequent pick for packaging machines and printing press linkages reading PWKR..2RS: sealed double-row cylindrical roller cam follower; the 2RS suffix means integral contact seals for maintenance-free track duty typical applications include robotic arm track guidance, paper mill web guide rollers and automatic assembly machine linkages this size is commonly specified for robotic arm track guidance and paper mill web guide rollers, where the 35 mm track diameter and 16 mm stud fit standard cam and rail geometries in automatic assembly machine linkages the 35 mm outer ring provides the rolling contact while the threaded stud simplifies mounting; the 160 g mass is low enough for rapid indexing cycles the sealed twin-row construction is the heaviest cam follower — verify the drive can accelerate the mass at the required cam rate the integral flanges and seals add width; verify the track channel accommodates the full B dimension plus flange protrusion
Typical equipment & failure modes
Common applications
- automatic assembly machine linkages
- robotic arm track guidance
- food processing line track rollers
- printing press roller followers
Known failure patterns
- 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
- the sealed twin-row construction is the heaviest cam follower — verify the drive can accelerate the mass at the required cam rate
- the integral flanges and seals add width; verify the track channel accommodates the full B dimension plus flange protrusion
- the sealed construction prevents relubrication; the grease fill is sized for the calculated L10 life at the printed speed and load

Frequently asked questions
What are the dimensions of the PWKR-35.2RS?
PWKR-35.2RS is a sealed full-complement cylindrical-roller cam follower with 35 mm outside diameter, 16 mm stud shank diameter and 52 mm overall width. The stud is 16 mm and the track contact diameter is 35 mm.
What does the PWKR designation mean?
The PWKR prefix identifies this as a sealed full-complement cylindrical-roller cam follower. In the SKF catalogue this designation carries the full specification including the 35x16x52 mm envelope and the 5000 r/min limiting speed.
What is the load capacity of PWKR-35.2RS?
The published basic dynamic load rating C is 11.9 kN and the basic static load rating C0 is 11.4 kN. These values already include the bending-stress correction for the thick-walled outer ring running on a track.
