Φ320 Electric Motorized Pulley Extended Shaft Split-Type Support Bracket Model 324 HT200 Cast Iron M24 Bolts 145kN

Model 324 Extended Shaft Electric Motorized Pulley Support Bracket (Bearing Housing)

The Model 324 support bracket is a heavy-duty split-type bearing housing specifically engineered for Φ320 extended shaft electric motorized pulleys. Cast from HT200 grey cast iron with an extended bearing chamber, thickened side ribs, and 145kN radial load rating, it provides superior shaft support stability for inclined and long-distance conveyor applications. The split-body design enables field maintenance without drum disassembly.

Key Specifications

Product Features

• Extended Bearing Chamber: Deeper bearing housing designed for extended shaft drums, providing wider bearing support span for enhanced operational stability.
• Thickened Side Ribs: Reinforced rib structure delivers superior deformation resistance under heavy climbing conveyor loads.
• Split-Type Design: Split-body construction enables on-site bearing and oil seal replacement without removing the entire drum assembly, reducing downtime.
• High-Precision Bearing Bore: Precision-machined bearing seat ensures low-noise operation and significantly extends drum bearing service life.
• Stress-Relieved Casting: Annealed blank casting guarantees long-term dimensional stability under varying load and temperature conditions.

Manufacturing Process

Sand Casting → Annealing (Stress Relief) → Precision Boring and Milling → Drilling and Tapping → Quality Inspection

Applications

Engineered for Φ320 extended shaft electric motorized pulleys in long-distance grain conveyors, light-duty stone conveying equipment, small inclined assembly line belt conveyors, and wood panel processing conveyor lines.

Installation Notes

• When assembling extended shaft drums, bracket spacing must strictly match drawing dimensions; never force-align the main shaft.
• Tighten split bolts diagonally in 2-3 staged passes to prevent bearing bore deformation and loss of roundness.
• After installation, manually rotate the drum to verify smooth operation without binding or eccentricity.
• In humid environments, periodically inspect the bracket base anti-rust coating and touch up any damaged areas promptly.
• Never lift the complete drum assembly using single-side bracket loading — always use balanced lifting points.
