Model 323 Electric Motorized Pulley Support Bracket (Bearing Housing)
The Model 323 support bracket is a split-type double-ear bearing housing engineered for Φ320 series electric motorized pulleys. Cast from HT200 grey cast iron with a rib-reinforced structure and precision-machined bearing seat, it provides reliable shaft support and vibration damping for light to medium-duty conveyor applications. The split design enables quick bearing and oil seal replacement without removing the entire drum assembly.

Product Features
- Superior Vibration Damping: HT200 cast iron provides excellent toughness and natural vibration absorption, resisting fatigue cracking from continuous conveyor vibration.
- Split-Type Design: The split-body structure allows bearing and oil seal replacement without removing the entire drum assembly, significantly reducing maintenance downtime.
- Rib-Reinforced Construction: Thickened reinforcement ribs prevent structural deformation under heavy conveying loads, ensuring long-term dimensional stability.
- Precision-Machined Bearing Seat: Bearing bore machined to coaxiality tolerance of ≤0.03mm, minimizing shaft wear and extending bearing service life.
- Stress-Relieved Casting: Annealed after sand casting to eliminate internal stresses, maintaining dimensional accuracy throughout the product lifespan.
Manufacturing Process
Sand Casting (Raw Blank) → Annealing (Stress Relief) → Bearing Bore Precision Boring → Mounting Surface Milling → Drilling and Tapping → Quality Inspection
Applications
Suitable for Φ320 light-duty belt conveyors, grain conveying equipment, express parcel sorting lines, small mining feeders, and packaging conveyor systems.
Installation Notes
- Clean all boring residue and burrs from the bearing bore before installation to prevent scratching the drum bearing outer ring.
- Ensure tight mating of split surfaces; tighten bolts evenly in diagonal sequence to prevent bearing seat deformation.
- Both side brackets must be horizontally aligned to ensure drum main shaft coaxiality and prevent uneven wear.
- Regularly grease with lithium-based lubricant to prevent bearing dry-running corrosion.
- Do not lift with single-side bracket overload — load must be evenly distributed across both double-ear mounting holes.
Packaging
