Bearing Housing & Bearing Assembly for screening equipment

Product Overview

As a fundamental transmission and support component exclusively designed for Nanchang Mining Machinery's screening equipment, the Bearing Housing & Bearing Assembly serves as the backbone of stable rotational motion in vibrating screens. Meticulously engineered to withstand continuous vibration, heavy loads, and harsh operating conditions, this assembly ensures smooth power transmission between key components, making it an indispensable spare part for reliable and efficient mining and aggregate screening operations.

Core Composition

The Bearing Housing & Bearing Assembly integrates high-performance components to deliver exceptional stability and durability, including:

• Bearing Housing: Heavy-duty cast iron or ductile iron housing (with reinforced rib structure) that provides rigid support and protection for internal bearings.

• Rolling Bearings: Premium deep groove ball bearings or spherical roller bearings (selected based on load requirements) for low-friction rotational motion.

• Sealing System: Double-lip oil seals + labyrinth seal combination that effectively prevents dust, water, and abrasive particles from entering the bearing cavity.

• Locking Device: Tapered sleeve or set screw locking mechanism that secures the bearing to the shaft, preventing axial and radial displacement.

• Lubrication Port: Standard grease nipple for convenient and regular lubrication, extending bearing service life.

• Mounting Flange/Base: Precision-drilled flange or base plate for seamless installation onto the screen's main frame.

Key Applications

This assembly is specifically tailored to Nanchang Mining's screening equipment, playing a pivotal role in:

• Mining Vibrating Screens: Supporting the main vibrating shaft and eccentric mechanism in primary, secondary, and tertiary ore screens, ensuring stable rotation under heavy material loads.

• Aggregate Screening Equipment: Such as YA series circular vibrating screens and YK series high-frequency screens, facilitating smooth operation of the screen box's vibration system during stone and sand classification.

• Heavy-Duty Screening Systems: Adapting to large-scale mining screens handling bulk materials, where reliable bearing support is critical to avoid unexpected downtime.

Core Advantages

1. Superior Load-Bearing Capacity: The robust housing and high-grade bearings are engineered to withstand radial and axial loads generated by continuous vibration and heavy material throughput.

2. Excellent Sealing Performance: The dual-seal design effectively isolates contaminants (dust, water, ore particles) common in mining environments, significantly extending bearing service life.

3. Smooth & Low-Noise Operation: Precision-machined housing and high-precision bearings minimize friction and vibration, reducing operational noise and wear on connected components.

4. Easy Installation & Maintenance: Standardized mounting dimensions and accessible lubrication ports simplify installation, maintenance, and bearing replacement, reducing downtime.

5. **** Compatibility: Custom-manufactured to match Nanchang Mining's screen models, ensuring perfect fit with the screen's shaft, frame, and vibration system.

6. Corrosion & Wear Resistance: The housing features anti-corrosion surface treatment (painting or galvanizing), while bearings are made of wear-resistant alloy steel for long-term reliability.
