Φ320 Electric Motorized Pulley Drum Model 323 Cast Iron Flange End Cover HT200 Φ85 Bearing Seat

Model 323 Electric Motorized Pulley Flange End Cover

The Model 323 flange end cover is a precision-cast sealing component designed for Φ320 series small electric motorized pulleys. Manufactured from HT200 grey cast iron, this end cover delivers superior oil sealing performance and long service life in oil-cooled drum motor applications.

Key Specifications

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.
