SKF 7311 Series Angular Contact Ball Bearing, 55mm Inside Diameter, 120mm Outside Diameter - 7311 BECBM


This angular-contact ball bearing is designed to transmit combined radial and axial loads in rotating equipment commonly found in automation and mechanical systems. It operates as a single-row unit with a parallel bore and an open end, suited to arrangements requiring directional axial support and straightforward assembly in driven components.

Features and Benefits:


• 40° contact angle enhances axial load capacity and alignment
• Machined-brass cage reduces friction and improves thermal stability
• Steel balls provide Durable rolling elements for sustained operation
• Rated dynamic load 85 kN for demanding load cycles
• Static load capacity 60 kN for high-hold applications
• Limiting speed 9,500 r/min for high-speed rotating assemblies

Applications


• Suitable for spindle supports in automated machining centres
• Ideal for rotary actuators in industrial robotics
• Used with electric motor shafts requiring axial support
• Can be used for gearbox intermediate shafts under combined loads
• Used for precision rotary encoders in electronics manufacturing

How should the bearing be mounted to maintain axial capacity?


Mount on accurately machined shafts with correct interference or locating fits to ensure the contact angle engages and axial preload is preserved during operation.

What maintenance considerations support long service life?


Regular lubrication compatible with steel rolling elements and brass cages, Plus contamination control at the open face, reduces wear and preserves performance.

How does the open end design affect installation choices?


An open end permits Visual inspection and easier re-lubrication access but requires Seals or shields in contaminated environments to protect raceways.

What operating environments is it suited for regarding speed and loads?


Best applied where rotational speeds approach but do not exceed 9,500 r/min and where combined radial and axial loads remain within the specified dynamic and static limits.
