When a misaligned shaft or an undersized bearing housing causes unexpected downtime on your conveyor line, agricultural equipment, or industrial machinery, engineers and maintenance technicians need a reliable, drop-in solution. The SUCHA series hanger type mounted bearings are engineered for exactly these demanding environments, offering a secure, self-aligning mount that compensates for minor shaft misalignment without requiring precision alignment during installation.
Each unit in the SUCHA201–SUCHA206 range consists of a cast iron or pressed-steel hanger housing paired with a self-aligning ball bearing insert. Bore diameters span 12 mm (0.47 in) through 30 mm (1.18 in), covering the most common shaft sizes found in light-to-medium industrial applications. The bearing insert features a spherical outer ring that seats into the housing, allowing angular misalignment of typically ±2°–3°.
Typical use cases include overhead conveyor shaft support in food-processing facilities, fan and blower shaft mounting in HVAC systems, and agricultural equipment such as grain augers and seed drills — all applications where a hanger-style (ceiling or underside) mount is required and where long-tail searches like "hanger bearing for conveyor shaft" or "pillow block bearing ceiling mount" describe the exact need.

Match the bore diameter to your shaft diameter: SUCHA201 fits 12 mm shafts, SUCHA202 fits 15 mm, SUCHA203 fits 17 mm, SUCHA204 fits 20 mm, SUCHA205 fits 25 mm, and SUCHA206 fits 30 mm. Measure your shaft with a vernier caliper before ordering to ensure a proper fit — a loose bore will cause vibration and premature wear.
A standard pillow block bearing mounts on a flat surface below the shaft (floor or frame). A hanger type bearing is designed to mount on an overhead structure, suspending the shaft beneath it. This makes hanger bearings the correct choice for conveyors, augers, and fan shafts where the mounting surface is above the shaft centerline.
The double-sealed bearing insert provides protection against dust and light moisture ingress, making these units suitable for dusty agricultural environments and lightly humid industrial settings. For direct washdown or fully outdoor exposed applications, consider additional housing protection or stainless-steel insert variants. Contact us to confirm suitability for your specific environment.
The set-screw locking method provides reliable axial retention for most light-to-medium duty applications. For heavy axial loads or high-vibration environments, it is advisable to use a shaft with a flat ground into it at the set-screw contact point to improve grip and prevent shaft damage. For very heavy axial loads, consider eccentric collar locking variants.
Yes — the SUCHA series uses a standard bearing insert that can typically be replaced independently of the housing, provided the housing is undamaged and the bore of the housing is within tolerance. This makes maintenance more cost-effective, as you replace only the worn insert rather than the entire assembly.
These bearings are compatible with standard steel shafts (mild steel, carbon steel, or stainless steel) ground to h6 or j6 tolerance for a proper fit. Avoid using them on shafts with heavy surface rust or out-of-round profiles, as this will compromise the set-screw grip and bearing alignment.
The bearing inserts are pre-lubricated at the factory and sealed, so they do not require routine re-lubrication in normal service conditions. If your application involves elevated temperatures, high speeds, or heavy contamination, periodic re-greasing via a grease fitting (where available) is recommended to extend service life.
