4202 ATN9

They're essentially two single row deep groove ball bearings assembled side by side in one wider unit, featuring two rings of balls in deep uninterrupted grooves. This gives them enhanced load capacity while keeping radial and bi directional axial load support.

1.Higher load capacity: They handle significantly greater radial loads, and also manage axial loads in both directions. 2.Improved rigidity & stability: Wider design reduces deflection and better resists vibration or misalignment. 3.Compact compared to two singles: Unlike using two single row bearings, they save axial space.

1.Higher friction and heat: More rolling elements increase friction, which may limit high-speed use. 2.Bulkier and heavier: Increased width and weight compared to single row bearings. 3.Precise alignment needed: Installation tolerances are tighter—misalignment can cause issues. 4.More costly & complex: Manufacturing demands are higher, and units are pricier than singles.

Popular in systems requiring robust load-handling in limited space, e.g.: 1.Gearboxes, motors, conveyors 2.Hoisting and construction machinery 3.Automotive (e.g. steering, hubs) Industrial/agricultural equipment.

1.Speed limits dip compared to single row types due to higher internal friction. 2.More rolling elements increase heat generation, needing better sealing and lubrication. 3.Opt for suitable lubricants and sealing based on your operating speed, temperature, and environment.

Ideal if you need: 1.Higher radial and bi directional axial capacity 2.Greater rigidity in a single unit 3.Axial space for two bearings is limited Avoid if: 1.You require very high speeds 2.You’re low on space/weight/budget 3.Tolerance for installation complexity is low
