SKF F2B 103-RM Radial Deep Groove Ball Bearing

SKF F2B 103-RM is a two-bolt flange-mount radial deep groove ball bearing unit with a 1-3/16 in bore (30.2 mm) and a cast-iron F2B flange housing. Inside, a single-row deep groove ball bearing provides reliable radial support, while a set-screw locking arrangement secures the shaft insert for a fixed, non-expansion mounting—designated as intermediate-duty service. The unit includes a contact seal to guard against dust and moisture and sustain lubrication in standard industrial environments. This mounted bearing unit is compact and ready for straightforward installation on small- to mid-size machinery, such as conveyors and packaging equipment, where predictable radial performance and easy maintenance are valued. Set-screw locking on the flange ensures secure retention on the shaft and facilitates serviceability without disassembly of the housing. The F2B 103-RM configuration represents SKF’s standard-duty flange-mounted option, balancing robust construction with a compact footprint for applications requiring a reliable, shielded bearing in tight spaces. This makes it suitable for quick replacement in service and streamlined spare-part stocking.
