Engineers, CNC builders, and robotics makers who demand repeatable, low-friction travel need a round flange linear bushing bearing that fits their shaft precisely and stays aligned under load. The LMFC series round flange linear bushing bearings are designed for exactly that use case.\u003c\/p\u003e\n    \u003cp\u003eEach LMFC bearing features a hardened steel outer shell with a round flange mounting face, housing recirculating ball circuits that ride directly on the shaft. Available in bore sizes from 6 mm (0.24 in) to 60 mm (2.36 in), with outer diameters ranging from 12 mm to 90 mm and body lengths from 35 mm to 209 mm, these bearings cover a wide range of motion system requirements. The flange diameter and bolt-circle pattern allow direct bolting to plates and carriages without additional adapters.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include CNC router Z-axis and gantry carriages requiring tight positional repeatability, 3D printer bed and extruder carriage assemblies where smooth travel reduces print artifacts, and industrial pick-and-place or linear actuator systems where the round flange simplifies carriage plate integration. The LMFC designation follows the standard LMF series envelope with a closed (C) ball-retainer design for quieter operation.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    Compatible with standard smooth round shafts (h6 or f7 tolerance) matching the listed bore diameter.
