160449A1 BUSHING CASE

Precision-Engineered Bushing for CASE Heavy Machinery

The 160449A1 BUSHING CASE is a high-grade mechanical component designed to restore the original precision, alignment, and performance of CASE heavy-duty machinery. Every element of this bushing represents advanced metallurgical engineering and exact machining, created to endure high loads, abrasive conditions, and continuous dynamic motion.

Manufactured under 3GEN Export’s OEM-standard production lines, the 160449A1 BUSHING CASE ensures tight dimensional tolerances, enhanced lubrication distribution, and long-term durability. It acts as the critical interface between moving components, absorbing frictional forces while maintaining rigidity across mechanical joints.

Role and Functionality of 160449A1 BUSHING CASE

Bushings are the unsung heroes of heavy equipment mechanics — designed to sacrifice themselves to protect far more expensive structural and hydraulic parts. The 160449A1 BUSHING CASE is strategically positioned in the pivot joints, loader arms, or boom linkages of CASE construction machinery. It creates a smooth rotational surface that supports the movement of pins and shafts under extreme stress.

Without the correct bushing installed, pins can seize or deform, alignment can drift, and operational vibration increases. Over time, this can lead to wear on the chassis, misalignment of the hydraulic cylinder eyes, and even structural cracking. Installing the 160449A1 BUSHING CASE prevents those issues — ensuring stability, uniform load distribution, and long-term operational reliability.

Technical Data and Manufacturing Standards

Each 160449A1 BUSHING CASE undergoes full CNC machining and precision grinding to ensure true concentricity. Components are manufactured under ISO 9001 and ISO 14001 quality frameworks, with strict dimensional control verified using coordinate measuring machines (CMMs).

Engineering Features

1. Dimensional Precision

The bore and outer diameters are held within ± 0.02 mm tolerance, guaranteeing an interference fit that eliminates radial play and ensures perfect alignment of pivot joints.

2. Hardened Surface Treatment

The wear zone of the 160449A1 BUSHING CASE is induction-hardened to > 58 HRC while the core remains tough and elastic. This dual-layer metallurgy resists cracking under impact while maintaining flexibility under dynamic stress.

3. Optimized Lubrication Design

Internal spiral grooves distribute grease evenly throughout the contact surface, preventing dry spots and minimizing friction. The central grease port allows easy maintenance through automated or manual greasing systems.

4. Corrosion and Dust Protection

A fine-grained surface finish combined with anti-oxidation coating provides protection against water, mud, and airborne abrasives, extending operational life even in the harshest job sites.

5. Noise and Vibration Reduction

Its precision-balanced geometry eliminates chatter and reduces vibration, resulting in smoother hydraulic operation, higher operator comfort, and longer service intervals.

Performance and Mechanical Properties

• Coefficient of Friction: ≤ 0.05 (with lubrication)

• Elastic Modulus: ≈ 210 GPa

• Axial Load Resistance: Up to 85 kN

• Thermal Expansion Coefficient: 1.2 × 10⁻⁵ K⁻¹

• Noise Level Reduction: Up to 12 % in hydraulic assemblies

These specifications translate into real-world benefits — smoother motion, reduced maintenance costs, and longer machine uptime.

Compatible CASE Models

The 160449A1 BUSHING CASE fits a wide range of CASE construction and earth-moving machinery, ensuring compatibility across several platforms:

CASE Backhoe Loaders

• CASE 580 Super N

• CASE 590 Super M

• CASE 695 ST

• CASE 580 N EP

CASE Excavators

• CASE CX130D

• CASE CX160C

• CASE CX210D

• CASE CX250C

CASE Wheel Loaders

• CASE 721G

• CASE 821G

• CASE 921F

• CASE 1021G

CASE Dozers & Graders

• CASE 1150M Dozer

• CASE 1650M Dozer

• CASE 856C Motor Grader

Across all these machines, the bushing serves the same mission: maintain proper articulation of booms, arms, and linkages under severe dynamic loads.

Installation Guidelines

1. Preparation: Clean the housing bore thoroughly and check for scoring or deformation.

2. Alignment: Verify that the bore axis aligns perfectly with the pin axis.

3. Press-Fit: Use a hydraulic press to seat the 160449A1 BUSHING CASE evenly — avoid hammering to prevent surface distortion.

4. Lubrication: Inject OEM-grade grease through the central port until a uniform film appears on both sides.

5. Testing: Move the pin manually to ensure free rotation without play or tight spots.

Following proper installation guarantees maximum service life and prevents premature wear on mating components.

Maintenance and Service Life

Routine maintenance extends the lifespan of the 160449A1 BUSHING CASE dramatically:

• Greasing Interval: Every 250 hours (normal use) / 100 hours (severe conditions)

• Inspection: Check for radial clearance > 0.5 mm or visible scoring

• Replacement Cycle: Typically after 20 000 – 25 000 hours (depending on application)

Adhering to these intervals prevents failures in pins and joints and keeps the entire articulation system stable over time.

Quality Testing and Certification

Every 160449A1 BUSHING CASE passes through a six-stage inspection process:

1. Raw Material Verification – Chemical composition and grain structure tests

2. Dimensional Accuracy Check – CMM measurement of critical diameters

3. Hardness Testing – Rockwell HRC confirmation of surface values

4. Surface Integrity Analysis – Profilometer measurement of Ra values

5. Load Simulation Testing – Dynamic stress testing under real world loads

6. Final Visual Inspection – Checking for micro cracks and defects

All production lots are fully traceable by serial and batch numbers, ensuring accountability and repeatability.

Field Performance Advantages

• Reduced Downtime: The 160449A1 BUSHING CASE extends service intervals by up to 40 %.

• Lower Maintenance Costs: Superior wear resistance means less frequent replacements.

• Enhanced Machine Stability: Minimizes vibration and improves load control.

• Extended Component Life: Protects pins and bores from metal-to-metal contact.

• Operator Comfort: Less vibration and noise translate into smoother operation.

The result is measurable productivity improvement in every operating environment—from quarries to large-scale infrastructure projects.
