How the 305800-C-2Z model number is decoded

the 32 mm outside diameter is the crowned track contact surface, the 10 mm bore takes the pin and the 14 mm overall width spreads the Hertzian contact across the thick-walled outer ring published ratings C 6.76 kN and C0 3.6 kN already include the outer-ring bending correction that track rollers require; the C/C0 ratio of 1.88 reflects two ball sets at a 30 deg contact angle fatigue load limit Pu 0.153 kN against a 10 mm bore gives 0.68 kN per mm of bore, and the 11,000 r/min figure is a mechanical limit rather than a thermal one the maximum permissible radial loads are Fr 4.4 kN dynamically and F0r 6.3 kN statically; because the permissible static load is the lower of F0r and C0, the 3.6 kN figure governs static selection here the 14 mm width carries 0.48 kN per mm, the ring section measures 11.0 mm between bore and track surface, and 62 g over a 32x14 mm envelope is 0.138 g per mm2 of projected area for high-speed cam duty the 10 mm bore and 14 mm width are those of the 32 series ball bearing at the same size code, while the 32 mm outside diameter is 2 mm larger than that bearing's 30 mm OD — this follows the SKF rule that cam rollers keep the ISO 15 dimension series except for the outside diameter at 10 mm bore this is the smallest cam roller in the catalogue chapter, the band chosen for compact cam drives, light indexing units and small transfer mechanisms where the 32 mm track diameter is already the largest envelope that fits 3058 is the crowned double row cam roller: two ball sets on a 30 deg contact angle inside a thick-walled ring whose running surface is ground crowned (400 mm radius), which is the standard surface for the double row design the 30 deg contact angle of the two ball sets is what gives the double row roller its tilting stiffness — under a moment load the rows react in opposite directions instead of unloading one edge of the ring the 2Z suffix on this roller denotes sheet steel shields rather than contact seals — effective against coarse contamination, but the design also provides a lubrication hole in the inner ring so that grease can be replenished through the pin typical duties are paper converting web guides, textile machinery cam gear and food processing index conveyors this size is regularly specified for paper converting web guides and textile machinery cam gear, where the 32 mm ring rides the cam profile and the 10 mm bore takes a g6 pin the two ball rows and the 14 mm wide ring make food processing index conveyors a natural fit; the 62 g mass keeps the follower inertia low enough for rapid oscillating cam motion read the loading direction before selecting the contact angle: the 30 deg double row design is strong radially and in tilt, but continuous axial load on the outer ring is outside its intended duty the polyamide snap cage has a lower temperature ceiling than the steel ribbon cage — respect the lubricant and cage limits when the application runs hot

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• relubrication is only possible through the inner-ring lubrication hole, which needs a matching duct in the pin; without that duct the roller is effectively sealed for life
• read the loading direction before selecting the contact angle: the 30 deg double row design is strong radially and in tilt, but continuous axial load on the outer ring is outside its intended duty
• the 2Z shows as a sheet steel shield, so it will not hold grease as tightly as a contact seal and will not exclude fine abrasive dust from wash-down environments
