Engineers, fabricators, and equipment builders working on conveyors, augers, fans, and agricultural machinery rely on hanger-type pillow block bearings to mount shafts from below or at angle — without compromising alignment or load capacity. The UCHA series is purpose-built for exactly these demanding scenarios.\u003c\/p\u003e\n    \u003cp\u003eThis listing covers the UCHA204 through UCHA210 hanger-type mounted bearing units. Each unit pairs a cast iron or pressed-steel hanger housing with a self-aligning insert bearing, available in bore sizes ranging from 20 mm (0.79 in) to 50 mm (1.97 in). The set-screw locking collar secures the shaft firmly within the bore, while the two-bolt hanger bracket allows ceiling or overhead frame mounting. Overall housing width typically spans 60–130 mm (2.36–5.12 in) depending on the selected size.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include grain auger shaft support in agricultural equipment, overhead conveyor line shaft mounting in food processing or packaging facilities, and fan or blower shaft suspension in HVAC and ventilation systems — all scenarios where a hanger-type mount outperforms a standard pillow block in space efficiency and alignment flexibility.\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 metric shafts from 20 mm to 50 mm.
