159449A1 BUSHING CASE

High-Precision Bushing Solution for CASE Heavy Machinery

The 159449A1 BUSHING CASE is a premium-grade mechanical component engineered to deliver flawless performance under the extreme conditions faced by CASE Heavy Machinery. This part is not just a replacement—it is a reinforcement of your machine’s precision, stability, and long-term structural integrity.

Supplied by 3GEN Export, an OEM-level manufacturer and global parts supplier, the 159449A1 BUSHING CASE is designed to meet the rigorous mechanical standards of the construction, mining, and excavation industries. Whether your CASE machine operates in dense clay, abrasive rock, or under constant load, this bushing maintains alignment, absorbs shock, and preserves the life of surrounding components.

Understanding the Role of the 159449A1 BUSHING CASE

A bushing is a seemingly simple part, but it performs one of the most critical functions inside heavy equipment: it acts as a protective barrier between moving parts. The 159449A1 BUSHING CASE reduces friction, distributes stress, and ensures seamless rotational movement.

In a CASE backhoe loader, excavator, or wheel loader, the bushing prevents metal-to-metal contact in pivot joints—areas constantly under dynamic load. Without a precisely fitted bushing, pin and bore wear accelerates, resulting in costly repairs and operational downtime.

This particular bushing variant is designed to sustain radial and axial forces while maintaining tight mechanical tolerances. It helps your machine stay true to its factory-calibrated alignment, keeping it smooth, powerful, and efficient even after thousands of working hours.

Technical Overview and Manufacturing Excellence

Every 159449A1 BUSHING CASE undergoes CNC machining, multi-stage heat treatment, and micro-finishing. Each production batch is tested for hardness, dimensional accuracy, and concentricity. The result is a bushing that delivers perfect fitment and long-term mechanical endurance—exactly what your CASE machine needs to stay productive and reliable.

Engineering Features

1. Precision Geometry

The bushing’s cylindrical profile is ground to a tolerance of ± 0.02 mm, guaranteeing perfect seating within the bore. Such precision eliminates micro-movement that can cause wear rings and noise over time.

2. Optimized Lubrication System

An internal oil channel ensures consistent grease distribution along the full contact surface, reducing friction and preventing dry-run damage. Even under continuous load, lubrication remains uniform, minimizing temperature rise and surface scoring.

3. Enhanced Wear Resistance

The 159449A1 BUSHING CASE is treated through induction hardening and tempering. Its internal hardness ensures high resistance against micro-pitting and galling, while the tough core maintains elasticity under shock loads.

4. Corrosion and Dust Protection

The bushing’s polished finish and anti-oxidation coating protect it from moisture, dirt, and aggressive working conditions, extending lifespan and keeping maintenance predictable.

5. Noise and Vibration Control

The precision-fit design minimizes vibration and operational noise, improving operator comfort and reducing fatigue on structural components.

Mechanical Performance

• Dynamic Load Capacity: > 70 kN

• Static Load Capacity: > 90 kN

• Coefficient of Friction: ≤ 0.05 with proper grease

• Service Temperature: −45 °C to +180 °C

• Axial Displacement Allowance: ± 0.2 mm

• Roundness Error: ≤ 0.01 mm

These values represent the culmination of advanced metallurgy and controlled manufacturing processes, ensuring stability under heavy stress and repetitive cycles.

Installation and Alignment Guide

To ensure optimal performance and longevity, 3GEN Export recommends the following installation protocol:

1. Preparation: Thoroughly clean the housing bore and mating surfaces. Remove burrs, debris, and old grease.

2. Alignment: Check the alignment of the bore and pin axis before installation to prevent edge loading.

3. Press-Fit Assembly: Use a hydraulic or mechanical press for uniform insertion. Never strike directly with a hammer.

4. Lubrication: Apply OEM-approved assembly grease through the central hole before reassembling components.

5. Verification: After installation, check for smooth rotational movement and confirm grease flow through all channels.

Following these guidelines ensures maximum lifespan and consistent performance.

Maintenance and Service Interval

Proper lubrication is key to preserving the bushing’s integrity:

• Re-grease every 250 operating hours under normal conditions.

• In muddy or abrasive environments, shorten to 100 hours.

• Inspect clearance and pin wear at each maintenance interval.

• Replace if radial clearance exceeds 0.5 mm or if visible scoring is observed.

By following this schedule, the 159449A1 BUSHING CASE can exceed 20,000 working hours without compromising fit or function.

Quality Control and Testing

Each unit produced under 3GEN Export’s OEM program undergoes:

1. Dimensional Verification via CMM inspection.

2. Hardness Testing (Rockwell C) to confirm heat treatment.

3. Lubrication Flow Analysis for channel accuracy.

4. Load Simulation Testing to replicate real operating conditions.

5. Surface Integrity Examination under microscopic inspection.

6. Traceability Marking with batch code and inspection certificate.

The outcome is a part that meets or exceeds CASE’s OEM standards for durability and precision.
