FR25ZZ Flange Bearing Key specifications Model: FR25ZZ Type: Shielded flange ball bearing (ZZ double shields) Bore: 1/8 in (0.125 in) / 3.175 mm Outer diameter: 5/16 in (0.3125 in) / 7.938 mm Width: 9/64 in (0.1406 in) / 3.571 mm Quantity: 5 pieces per order What it does Provides low-friction, smooth rotation while supporting radial loads in small assemblies. Flange simplifies mounting and helps keep the bearing aligned, reducing setup time and risk of misalignment. ZZ double shields protect against dust and contamination to extend service life and improve reliability in light-duty applications. Why you need it (benefits) Compact solution for constrained spaces where a standard flangeless bearing won’t secure reliably. Simplifies installation: flange alignment removes the need for additional locating hardware in many designs. Improves uptime: shielded design reduces contaminant ingress, helping bearings last longer in continuous, lightweight service. Consistent fit: sized for 1/8 in shafts and standard FR25 flange mounting for straightforward replacement or retrofit. Performance and compatibility Designed for lightweight, continuous operation in small machines and mechanisms. Best suited to radial load support and smooth rotational motion in compact assemblies. Direct fit for 1/8 in (0.125 in) shafts; matches standard FR25 flange mounting dimensions. Typical applications Robotics: compact joints and small articulating arms that need reliable, low-friction rotary support. 3D printers and small CNC machines: gantry mounts or guide wheel bearings for smoother motion and easier alignment. Light-duty conveyors and automation modules: dependable, easy-to-mount bearings for tight spaces and low to moderate duty cycles.
