How to find the right Mounted Hanger Bearings AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Mounted Hanger Bearings
- Hanger style and conveyor size match
- Match the hanger style, conveyor diameter and coupling shaft diameter of the existing screw conveyor. Use the CEMA hanger style designation where the conveyor follows CEMA standards. Hanger bearings are not universal, so the mounting pattern and bore must fit the existing hanger and shaft.
- Bearing material for the product conveyed
- Hard iron suits abrasive or hot material. Bronze or oil-impregnated bronze suits general duty. UHMW or nylon suits wet, food or corrosive service. Oil-impregnated wood suits light, dry service. Material choice decides wear life and whether the bearing contaminates the product.
- Temperature limit
- Keep plastic bearings within their rated temperature. Use metallic bearings for hot material. UHMW and nylon soften and deform at elevated temperatures.
- Lubrication method
- Decide whether the application allows grease fittings. Choose a self-lubricating material where grease would contaminate the product. Grease migration is unacceptable in food or chemical service.
- Coupling shaft wear compatibility
- Pair hard iron bearings with hardened coupling shafts. A soft shaft running in a hard iron bushing wears the shaft instead of the bearing.
Brands that matter
- Martin Sprocket & Gear: Major screw conveyor component maker that offers hangers and bearings in multiple materials.
- KWS Manufacturing: Screw conveyor manufacturer that supplies replacement hanger bearings.
- Screw Conveyor Corporation: Long-established screw conveyor maker with hanger components.
- Continental Conveyor: Conveyor equipment maker with screw conveyor parts.
What to avoid
- Ordering by shaft size alone without confirming the hanger style.
- Plastic bearings in hot or highly abrasive service.
- Greased bronze bearings in food lines where lubricant can reach the product.
- Hard iron bearings on unhardened coupling shafts.
Questions
Are these the same as pillow block bearings?
No. Screw conveyor hanger bearings are plain bushing-type bearings that sit inside the trough to support the screw between its ends. They are sized to the hanger and coupling shaft, not to ball-bearing interchange codes.
