How the 361206-R model number is decoded
the 72 mm outside diameter is the crowned track contact surface, the 30 mm bore takes the pin and the 16 mm overall width spreads the Hertzian contact across the thick-walled outer ring published ratings C 17.4 kN and C0 9.5 kN already include the outer-ring bending correction that track rollers require; the C/C0 ratio of 1.83 reflects a single deep groove ball set fatigue load limit Pu 0.4 kN against a 30 mm bore gives 0.58 kN per mm of bore, and the 5,300 r/min figure is a mechanical limit rather than a thermal one the maximum permissible radial loads are Fr 14.6 kN dynamically and F0r 20.8 kN statically; because the permissible static load is the lower of F0r and C0, the 9.5 kN figure governs static selection here the 16 mm width carries 1.09 kN per mm, the ring section measures 21.0 mm between bore and track surface, and 340 g over a 72x16 mm envelope is 0.295 g per mm2 of projected area for medium-speed cam duty dimensionally this is a 62 dimension series of deep groove ball bearings at 30 mm bore with a thick-walled outer ring pushed out to 72 mm (the base bearing measures 62 mm); the additional ring wall is what resists bending when the roller is unsupported in a housing at 30 mm bore this is the largest cam roller listed; the 16 mm width gives 17.4 kN dynamic capacity but the limiting speed drops to 5,300 r/min, so it suits slow, heavily loaded cams reading 3612.. R: single row cam roller built on a deep groove ball bearing, riveted ball-centred stamped steel cage, crowned running surface and NBR contact seals on both sides the standard SKF cam roller ring is crowned to a 400 mm radius; this is what keeps the contact patch away from the ring edges when the cam plate is not perfectly parallel typical duties are food processing index conveyors, packaging machine timing cams and glass handling line guides this size is regularly specified for food processing index conveyors and packaging machine timing cams, where the 72 mm ring rides the cam profile and the 30 mm bore takes a g6 pin the single ball row and the 16 mm wide ring make glass handling line guides a natural fit; the 340 g mass keeps the follower inertia low enough for rapid indexing cycles the permissible static load is the lower of F0r and C0, not C0 alone — sizing on C0 will overload the outer ring in a static or slow-motion cam position the pin must be machined to g6; an undersized or worn pin lets the inner ring creep and changes the effective internal clearance
Typical equipment & failure modes
Common applications
- conveyor diverters and transfer stations
- food processing index conveyors
- sheet metal forming press feeds
- tube and wire drawing guides
Known failure patterns
- the crowned running surface is standard, so the track must still be a smooth continuous profile — a step or weld spatter on the cam will brinell the ball raceway
- the NBR contact seals make this a greased-for-life unit; adding a relubrication line is pointless and forcing grease past the lips can dislodge them
- the permissible static load is the lower of F0r and C0, not C0 alone — sizing on C0 will overload the outer ring in a static or slow-motion cam position
- the pin must be machined to g6; an undersized or worn pin lets the inner ring creep and changes the effective internal clearance
- the single row design has the lowest tilting-moment capacity in the chapter; if the cam track is not parallel to the roller axis, the load moves onto one edge of the ring
- heat stabilisation here only reaches 120 degC, so exposure to higher temperatures will dimensionally destabilise the rings and shorten the seal life

Frequently asked questions
What are the dimensions of 361206-R?
361206-R is a single row cam roller with a 30 mm bore, 72 mm outside diameter and 16 mm overall width. The 72 mm ring is the track contact surface and the 30 mm bore takes a pin machined to tolerance class g6.
What does the R designation mean?
361206 R is the SKF catalogue designation: the 3612 prefix fixes the single row deep groove basis with a thick-walled outer ring, and the R suffix means NBR contact seals on both sides.
What is the load capacity of 361206-R?
The basic dynamic load rating C is 17.4 kN and the basic static load rating C0 is 9.5 kN, both already corrected for outer-ring bending. The maximum permissible radial loads are Fr 14.6 kN and F0r 20.8 kN, and the permissible static load is the lower of F0r and C0.
