SKF 3311 Series Ball Bearing, 55mm Inside Diameter, 120mm Outside Diameter - 3311 ATN9/C3
This ball bearing is a two-row angular contact unit designed to support combined radial and axial loads in machinery. It features steel races and rolling elements, an open configuration for maintenance access, and a non-metallic cage to reduce noise and friction during operation. The design suits rotating assemblies in precision equipment where controlled internal clearance is required.
Features and Benefits:
• 30° contact angle provides axial load-carrying capability • C3 internal clearance allows thermal expansion accommodation • Dynamic load capacity 112 kN improves operational durability • Static load capacity 81.5 kN resists static overloads • Limiting speed 5,300 r/min supports high-speed applications • Grooved raceways enhance accurate load distribution
Applications
• Suitable for spindle systems in automation equipment • Ideal for electric motor bearing arrangements • Used for precision gearboxes in industrial machinery • Can be used for rotary assemblies in electronic manufacturing
What materials contact directly with rolling elements?
The rolling elements and raceways are MADE from steel to provide hardened contact surfaces and wear resistance.
How does the open end type affect lubrication options?
The open design permits the use of external lubrication methods and simplifies re-lubrication intervals for ongoing maintenance.
What cage characteristics influence noise and friction?
The cage is non-metallic, which typically reduces vibration transmission and lowers friction compared with metal cages.
How does the bearing arrangement manage misalignment or shaft deflection?
The double-row angular contact configuration distributes loads across both rows, offering improved stiffness and tolerance to minor shaft deflection.
Are there environmental or regulatory considerations for selection?
The product meets RoHS requirements, indicating restricted use of certain hazardous substances in its constituent materials.
