These UC series metric self-lubricating bearing inserts are engineered for engineers, maintenance technicians, and serious DIY builders who demand dependable radial load support with minimal upkeep.\u003c\/p\u003e\n\u003cp\u003eEach bearing insert is manufactured from bearing-grade steel with a self-lubricating design that retains grease internally, reducing re-lubrication intervals. The bore range spans UC201 (12mm \/ 0.47 in) through UC216 (80mm \/ 3.15 in), covering the most common metric shaft diameters used in industrial and agricultural machinery. The outer spherical surface allows for angular misalignment compensation, typically up to 2–3°.\u003c\/p\u003e\n\u003cp\u003eThese UC bearing inserts are widely used in conveyor roller assemblies requiring continuous low-maintenance operation, agricultural equipment such as seeders and harvesters where field serviceability is limited, and general industrial machinery including fans, pumps, and packaging lines where shaft misalignment is common.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔩\u003c\/span\u003e Compatible with standard UC pillow block and flanged bearing housings (UCP, UCF, UCFL, UCFC series).
