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.
Packaging
Finished precision parts: Individual bubble wrap packaging, layered carton boxes on pallets. Raw castings: Steel pallet centralized stacking with outer waterproof tarpaulin cover.
