A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The housing supports and aligns the bearing, secures it to a machine frame, protects it from contaminants, and facilitates lubrication. It transfers loads from the shaft to the structure.
Common materials include cast iron, ductile iron, steel, stainless steel, and polymer composites. The choice depends on load, environment, and cost.
Select based on the bearing shaft diameter (bore diameter), load ratings, mounting dimensions, and operating conditions. Verify with the manufacturer's specifications.
Regular inspection for wear, corrosion, and proper lubrication is recommended. Ensure bolts are tightened to specified torque and seals are intact.
