SKF 7FB Series Roller Bearing, 50mm Inside Diameter, 110mm Outside Diameter - 31310/CL7C


This roller bearing is designed for radial load support in rotating machinery, providing shielded protection and single-row cylindrical rolling elements for continuous operation. It is intended for use where compact, high-capacity bearings are required and where contamination control and sustained rotational speeds are factors in component selection.

Features and Benefits:


• Sheet-metal cage reduces mass while maintaining internal spacing
• Shielded ends limit ingress for extended service intervals
• High static capacity of 120 kN supports heavy stationary loads
• Dynamic rating of 131 kN sustains repeated operational forces
• Limiting speed of 6,000 r/min enables higher rotational applications
• Single-row configuration simplifies axial alignment requirements

Applications


• Suitable for industrial gearboxes requiring Compact bearings
• Ideal for conveyor rollers with moderate contamination risk
• Used with electric motor drives operating at elevated speeds
• Can be used for pump shafts under radial loading
• Appropriate for machine-tool spindles with single-row needs

What bore diameter should the housing accommodate?


The internal bore measures 50 mm so the housing journal must match that dimension.

How does the shielding affect maintenance intervals?


Shields reduce particulate ingress which typically extends lubrication intervals compared with open designs.

Which component governs axial location in assemblies?


The single-row cylindrical design relies on shaft shoulders or external retainers to control axial positioning.

What material is used for the internal cage and how does it influence behaviour?


The cage is fabricated from sheet metal which provides dimensional stability while keeping centrifugal growth low.

What are the axial envelope measurements to consider during assembly?


The assembly requires allowance for a cone width of 29.25 mm and a cup width of 19 mm when fitting adjacent components.
