How the 361203-R model number is decoded

the 47 mm outside diameter is the crowned track contact surface, the 17 mm bore takes the pin and the 12 mm overall width spreads the Hertzian contact across the thick-walled outer ring published ratings C 8.84 kN and C0 4.25 kN already include the outer-ring bending correction that track rollers require; the C/C0 ratio of 2.08 reflects a single deep groove ball set fatigue load limit Pu 0.18 kN against a 17 mm bore gives 0.52 kN per mm of bore, and the 8,500 r/min figure is a mechanical limit rather than a thermal one the maximum permissible radial loads are Fr 8.15 kN dynamically and F0r 11.6 kN statically; because the permissible static load is the lower of F0r and C0, the 4.25 kN figure governs static selection here the 12 mm width carries 0.74 kN per mm, the ring section measures 15.0 mm between bore and track surface, and 110 g over a 47x12 mm envelope is 0.195 g per mm2 of projected area for medium-high-speed cam duty dimensionally this is a 62 dimension series of deep groove ball bearings at 17 mm bore with a thick-walled outer ring pushed out to 47 mm (the base bearing measures 40 mm); the additional ring wall is what resists bending when the roller is unsupported in a housing at 17 mm bore this size balances load capacity against envelope: 8.84 kN of dynamic capacity in a 47 mm ring, with the 12 mm width still narrow enough for compact cam plates 3612.. R is the single row cam roller: heat stabilised to at least 120 degC, rated with internal clearance C3, and sealed rather than shielded so it needs no relubrication in normal duty the ring profile here is crowned (400 mm radius) rather than flat, which is the standard SKF cam roller surface and the reason a single row roller tolerates modest track angularity typical duties are cam drives and indexing mechanisms, woodworking machinery feed cams and bottle filling carousel cams this size is regularly specified for cam drives and indexing mechanisms and woodworking machinery feed cams, where the 47 mm ring rides the cam profile and the 17 mm bore takes a g6 pin the single ball row and the 12 mm wide ring make bottle filling carousel cams a natural fit; the 110 g mass keeps the follower inertia low enough for rapid indexing cycles heat stabilisation here only reaches 120 degC, so exposure to higher temperatures will dimensionally destabilise the rings and shorten the seal life 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

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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
• 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
