LIUGONG 14C0233 Track Roller Assembly for CLG922 excavator Undercarriage components supplied by HELI-cqctrack

The LIUGONG 14C0233 CLG922 Track Roller Assembly is a critical undercarriage component engineered specifically for the LiuGong CLG92 series wheel loaders. This assembly is designed to bear the machine’s entire weight, guide the track chain, and ensure smooth travel over varied terrains. Its precision engineering and robust construction are pivotal for maximizing service life, reducing downtime, and maintaining optimal machine efficiency.

Comprehensive Structural Analysis

The Track Roller Assembly is a fully sealed and lubricated unit. Its sophisticated structure can be broken down into the following key components:

1. Outer Rim & Tread

• Material: Manufactured from high-carbon, alloy steel.
• Process: Forged for superior grain structure and then machined to precise tolerances.
• Surface Treatment: The tread undergoes high-frequency induction hardening to a significant depth, followed by precision grinding. This process creates an extremely hard, wear-resistant outer surface while maintaining a tough, shock-absorbing core. The hardened tread is specifically profiled to match the track chain links, minimizing point contact stress and promoting even wear.

2. Hub & Inner Structure

• The hub is integrally designed with the outer rim, forming the main roller body. It houses the bearing and sealing systems. The internal machined surfaces are finely finished to ensure perfect fit and alignment with the bearings and shaft.

3. Main Shaft (Spindle)

• Function: This is the stationary core of the assembly, which is pressed and secured into the track frame.
• Material: Made from high-tensile strength chrome-molybdenum steel.
• Characteristics: The shaft is case-hardened (e.g., carburized) to provide a hard, wear-resistant exterior where it contacts the bearings, and a ductile interior to withstand high bending and shock loads without fracturing.

4. Bearing System

• Type: Typically utilizes a combination of high-capacity tapered roller bearings or durable journal bearings (bushings).
• Function: These bearings are responsible for allowing the roller to rotate freely around the stationary shaft while supporting immense radial loads. Tapered roller bearings are pre-loaded during assembly to eliminate axial and radial play, ensuring smooth rotation and preventing premature wear.

5. Multi-Layer Sealing System

• This is the heart of the roller’s longevity. The system typically consists of:
  • Primary Seal: A robust, spring-loaded radial lip seal that creates a dynamic barrier against contaminants.
  • Secondary Seal: Often an O-ring or another lip seal that acts as a backup.
  • Dust Lip: An external lip designed to exclude large abrasive particles like mud and sand.
  • Grease Cavity: The space between the seals is filled with special high-temperature, waterproof grease, which lubricates the seal lips and provides a positive barrier against moisture ingress.

6. End Caps / Flanges

• Pressed or welded onto the ends of the roller, these caps serve to retain the internal components and protect the sealing system from direct impact and debris buildup.

7. Lubrication Fitting

• A standard grease zerking fitting is provided, allowing for periodic purging and re-lubrication of the external seal cavity, a critical maintenance procedure for extending seal and roller life.

Key Performance Advantages

• Enhanced Durability: The hardened tread and forged body provide exceptional resistance to abrasion and impact from rocks, gravel, and other site debris.
• Superior Sealing: The multi-stage labyrinth seal effectively keeps contaminants out and retains lubricant in, even in wet, muddy, or dusty conditions.
• Reduced Operating Costs: By providing extended service intervals and protecting the internal bearing system, this assembly helps lower the total cost of ownership.
• Optimal Machine Performance: Precision manufacturing ensures smooth rotation, which reduces track noise, minimizes vibration, and improves fuel efficiency by reducing travel resistance.
• Perfect Compatibility: As a genuine LiuGong part (14C0233), it guarantees perfect fitment, optimal performance, and preserves your CLG922 loader’s warranty.
