Product Features
- Superior Sealing: HT200 grey cast iron offers excellent oil resistance and corrosion protection, ideal for long-term immersion in lubricating oil environments.
- Leak-Proof Design: High-precision turned flange face ensures gap-free mating with the drum body, eliminating oil leakage risks.
- Uniform Clamping: Evenly distributed locking bolt holes around the outer ring provide balanced clamping force, preventing flange deformation.
- Precise Alignment: Center stepped bearing hole is bored in a single setup, ensuring accurate bearing positioning and high concentricity.
- Extended Service Life: Interior coated with red oil-resistant anti-rust primer to isolate lubricant corrosion and prolong casting durability.
Manufacturing Process
Sand Casting → Annealing → Flange Face Turning → Center Bearing Hole Boring → Tapping → Red Anti-Rust Primer Coating
Applications
Ideal for Φ320 light-duty electric motorized pulleys used in grain conveying, express parcel sorting, and small packaging assembly line belt conveyors.
Installation Notes
- Install oil-resistant rubber gasket on flange mating surface; tighten bolts diagonally in stages.
- Clean center bearing hole burrs and molding sand before assembly to avoid scratching bearing outer ring.
- Both end covers must use same model; do not mix different sizes.
- Check interior primer condition before filling lubricant; reapply if damaged.
- Inspect flange seal area for leakage during first oil change at 300 operating hours.
Packaging
Finished products: Individual bubble wrap, layered carton boxes. Raw castings: Palletized bulk stacking with waterproof covering.
