How the 361204-R model number is decoded

the 52 mm outside diameter is the crowned track contact surface, the 20 mm bore takes the pin and the 14 mm overall width spreads the Hertzian contact across the thick-walled outer ring published ratings C 11.4 kN and C0 5.5 kN already include the outer-ring bending correction that track rollers require; the C/C0 ratio of 2.07 reflects a single deep groove ball set fatigue load limit Pu 0.232 kN against a 20 mm bore gives 0.57 kN per mm of bore, and the 7,000 r/min figure is a mechanical limit rather than a thermal one the maximum permissible radial loads are Fr 7.5 kN dynamically and F0r 10.6 kN statically; because the permissible static load is the lower of F0r and C0, the 5.5 kN figure governs static selection here the 14 mm width carries 0.81 kN per mm, the ring section measures 16.0 mm between bore and track surface, and 150 g over a 52x14 mm envelope is 0.206 g per mm2 of projected area for medium-high-speed cam duty the 20 mm bore and 14 mm width are those of the 62 series ball bearing at the same size code, while the 52 mm outside diameter is 5 mm larger than that bearing's 47 mm OD — this follows the SKF rule that cam rollers keep the ISO 15 dimension series except for the outside diameter the 20 mm bore places this in the medium band where the thick-walled outer ring is deep enough to carry 11.4 kN without excessive edge stress on the track the 3612 designation means the lightest cam roller design in the chapter, based on a single deep groove ball set; the R suffix marks the NBR contact seals that keep the factory grease fill in place for life the crowned running surface is standard on this design — the 52 mm ring is ground to a radius of 400 mm so that a slightly misaligned or deflecting track does not concentrate load on one edge typical duties are automatic assembly line actuators, robotic gantry track guidance and printing press linkage rollers this size is regularly specified for automatic assembly line actuators and robotic gantry track guidance, where the 52 mm ring rides the cam profile and the 20 mm bore takes a g6 pin the single ball row and the 14 mm wide ring make printing press linkage rollers a natural fit; the 150 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

Selection pitfalls — read before you substitute

• the pin must be machined to g6; an undersized or worn pin lets the inner ring creep and changes the effective internal clearance
• 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 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
