SKF Cylindrical Roller Bearing 50 mm Inside Diameter 110 mm Outside Diameter Shielded Sheet Metal Cage 7FB Series 31310/CL7C

SKF 31310/CL7C Cylindrical Roller Bearing is engineered for reliable radial load support with a 50 mm inside diameter and 110 mm outside diameter. It features a shielded design to protect against contaminants and a sheet metal cage that balances durability with low centrifugal growth. The bearing's single-row construction simplifies axial positioning, depending on shaft shoulders or external retainers.

This 7FB series bearing offers a high static load capacity of 120 kN, making it suitable for heavy stationary loads. It also carries a dynamic load rating of 131 kN, able to withstand repeated operational stress. The limiting speed reaches 6000 rpm, addressing applications demanding moderate to high rotational speeds.

With a cup width of 19 mm and cone width of 29.25 mm, proper axial clearance must be considered during assembly. Shielded ends significantly extend lubrication intervals by reducing particulate ingress, which is critical in industrial environments.

The sheet metal cage provides dimensional stability and reduced mass, enhancing performance across diverse conditions. This bearing is ideal for industrial gearboxes requiring compact bearings, conveyor rollers exposed to moderate contamination, electric motor drives at elevated speeds, pump shafts under radial loading, and machine-tool spindles needing single-row cylindrical bearings.

Sheet metal cage reduces mass while maintaining internal spacing. Shielded ends limit particulate ingress for extended service intervals. High static load rating of 120 kN supports heavy stationary loads. Dynamic load rating of 131 kN sustains repeated operational forces.

Limiting speed of 6000 rpm enables higher rotational applications. Single-row cylindrical design simplifies axial alignment requirements. Manufactured in Germany ensuring quality and reliability.

This SKF bearing aligns with industrial requirements in manufacturing, machinery maintenance, HVAC systems, and general mechanical engineering. It represents a high-performance solution in the Roller Bearing segment, ensuring durability and efficiency in demanding operations.
