Φ320 Electric Motorized Pulley Extended Shaft Model 324 Cast Iron Flange End Cover HT200 Φ90 Bearing Seat

Model 324 Extended Shaft Electric Motorized Pulley Flange End Cover

The Model 324 flange end cover is a heavy-duty sealing component engineered for Φ320 extended shaft electric motorized pulleys. Cast from HT200 grey cast iron with a thickened flange rim and extended bearing chamber, it delivers superior shaft support and oil sealing in demanding continuous-duty applications.

Key Specifications

Product Features

• Extended Bearing Chamber: Deeper center bearing housing accommodates extended shafts, providing longer bearing support distance for smoother and more stable operation.
• Leak-Proof Precision Seal: CNC-turned flange face ensures high-precision mating with the drum body, maintaining oil-tight sealing during continuous long-hour operation.
• Thickened Flange Rim: Reinforced flange edge resists warping and deformation even after repeated disassembly and reassembly cycles.
• Corrosion-Resistant Interior: Red oil-resistant anti-rust primer coating protects inner cavity from long-term lubricating oil exposure and chemical degradation.
• Stress-Relieved Casting: Annealed HT200 cast iron eliminates internal stress, maintaining flange flatness under alternating hot and cold operating conditions.

Manufacturing Process

Sand Casting → Annealing (Stress Relief) → CNC Flange Face Turning → Center Bearing Chamber Boring → Bolt Hole Tapping → Red Anti-Rust Primer Coating → Quality Inspection

Applications

Specifically engineered for Φ320 extended shaft electric motorized pulleys used in long-distance grain conveyors, light-duty stone transport lines, and wood panel processing conveyor systems.

Installation Notes

• When assembling extended shafts, ensure both end cover center holes are coaxial; never force-fit the shaft.
• Install intact oil-resistant rubber gasket on flange mating surface; tighten bolts evenly in diagonal sequence to prevent localized gaps.
• In humid or dusty environments, disassemble and inspect end cover seals and interior coating quarterly.
• Do not mix 323 and 324 model end covers — incompatible bearing chamber depth will cause bearing seizure.
• Clean accumulated oil residue and debris from end cover cavity during oil changes to prevent bearing wear.
