Ultra Heavy Duty Split Support Bracket Electric Motorized Pulley Cast Iron M36 Bolts 320kN

Φ500 Electric Motorized Pulley Ultra-Heavy-Duty Split Support Bracket Model 505 HT250 Cast Iron M36 Bolts 320kN

Model 505 Ultra-Heavy-Duty Electric Motorized Pulley Support Bracket (Bearing Housing)

The Model 505 support bracket is the flagship ultra-heavy-duty bearing housing engineered for Φ500 large electric motorized pulleys in the most extreme industrial environments. Cast from HT250 high-strength grey cast iron with a fully thickened shell, dense triangular reinforcement ribs, and extra-wide split mating surface, it delivers 320kN radial load capacity for 24/7 continuous operation in large mining, port, and steel mill conveyor systems.

Key Specifications

Product Features

• 320kN Load Rating: The highest capacity in the series, engineered with HT250 high-strength cast iron for impact and alternating load resistance in large mining and port heavy-duty conveying.
• Full Thickened Shell with Dense Triangular Ribs: Completely reinforced housing structure prevents plastic deformation even under decades of continuous heavy-load operation.
• Extra-Wide Split Sealing Surface: Extended split joint with superior locking rigidity ensures bearing bore maintains perfect roundness under high-speed, heavy-load conditions.
• Oversized Bearing Chamber: Extra-large bearing housing accommodates heavy-duty spherical roller bearings for ultimate radial and axial load capacity.
• CNC Precision Machined: Tight dimensional tolerances on both mounting plane and bearing bore guarantee low-noise, vibration-free operation across the entire duty cycle.

Manufacturing Process

Coated Sand Precision Casting → High-Temperature Stress-Relief Annealing → Large-Scale CNC Boring and Milling → M36 Bolt Hole Tapping → Final Quality Inspection

Applications

Purpose-designed for Φ500 large heavy-duty electric motorized pulleys in extreme environments: large-scale mining main conveyor belts, port bulk cargo handling lines, steel mill waste material conveyors, quarry heavy-duty transfer belts, and large grain terminal conveyor systems.

Installation Notes

• Must use M36 Grade 10.9 high-strength bolts exclusively; tighten diagonally in multiple staged passes for uniform seating.
• Apply oil-resistant waterproof sealant evenly across split mating surfaces to prevent lubricant leakage and dust ingress.
• Mounting plane level error between both brackets must be controlled within 0.03mm to prevent main shaft bending or fatigue fracture.
• For 24/7 continuous heavy-duty operation, inspect bearing temperature and replenish grease weekly.
• During complete assembly lifting, use dual lifting eyes with synchronized loading — single-point or single-side lifting is strictly prohibited.

Packaging

Single finished precision parts: Full bubble wrap encapsulation with heavy-duty reinforced carton boxes. Bulk raw castings: Heavy steel pallet with full waterproof stretch film wrapping and reinforced metal corner guards at all edges.
