KBV14210 BUSHING CASE

Precision-Engineered Bushing for CASE Heavy Machinery

The KBV14210 BUSHING CASE is a high-performance, OEM-grade component designed to ensure exceptional mechanical stability in CASE construction and earth-moving machinery. Every millimeter of this precision bushing represents advanced metallurgy, surface science, and machining expertise—qualities that define the reputation of 3GEN Export as a trusted global supplier.

Built for reliability under continuous stress and exposure to abrasive conditions, this bushing restores the original performance of CASE loaders, excavators, and backhoes. It reduces friction, minimizes vibration, and protects vital structural parts from premature wear—extending both service life and operational efficiency.

Role and Functionality of KBV14210 BUSHING CASE

In heavy machinery, bushings act as self-sacrificing yet essential components that absorb mechanical stress, allowing pins and joints to articulate freely without damaging the surrounding metal.

The KBV14210 BUSHING CASE sits at the heart of these joint assemblies, creating a buffer between moving parts. It ensures consistent pivot motion and absorbs axial and radial loads during extreme working cycles—whether in quarry excavation, material loading, or grading operations.

Without a correctly fitted bushing like the KBV14210, mechanical play develops between pins and bores, leading to misalignment, uneven load transfer, and costly component failure. This is why using an OEM-spec, precision-machined bushing is not merely a replacement decision—it’s a strategic investment in mechanical longevity.

Technical Data and Manufacturing Standards

Each KBV14210 BUSHING CASE is precision-machined using advanced CNC lathes and grinding systems. The production line operates under ISO 9001-certified protocols and every component passes through micrometer-level dimensional inspection. This guarantees a tight, consistent fit inside OEM housing dimensions.

Engineering Advantages

1. Dimensional Accuracy

Machined with a tolerance of ± 0.02 mm, the KBV14210 BUSHING CASE ensures a perfect press-fit, eliminating lateral play and keeping pin alignment exact even after prolonged use.

2. Advanced Lubrication System

The spiral internal oil channels and central grease port ensure uniform lubrication across the bearing surface. This continuous film of grease prevents micro-pitting, heat build-up, and surface fatigue.

3. Superior Material Treatment

Induction-hardened steel provides a robust wear layer with a resilient, ductile core. This dual-structure profile allows the bushing to absorb impact loads without cracking, even under sudden shock stress.

4. Noise and Vibration Reduction

Thanks to precise geometry and surface finish, the KBV14210 reduces mechanical noise and vibration—essential for maintaining operator comfort and structural integrity of connected arms and booms.

5. Corrosion and Dust Resistance

The outer coating resists rust, oxidation, and abrasion from dust, mud, and water ingress. Even in coastal or mining environments, its performance remains stable.

Performance Parameters

• Coefficient of Friction: ≤ 0.05 (with proper grease)

• Concentricity Deviation: ≤ 0.01 mm

• Axial Displacement Tolerance: ± 0.2 mm

• Tensile Strength: > 800 MPa

• Elastic Modulus: ~ 210 GPa

• Operating Cycle Resistance: > 2 × 10⁷ cycles

These specifications translate into tangible field benefits: longer replacement intervals, reduced downtime, and smoother hydraulic actuation.

Compatible CASE Models

The KBV14210 BUSHING CASE fits a wide range of CASE machines across several categories:

CASE Backhoe Loaders

These machines rely on bushings to maintain accurate articulation in boom, dipper, bucket, and chassis linkages. The KBV14210 provides the exact tolerance and material hardness required for these mechanical joints.

Installation Procedure

Correct installation of the KBV14210 BUSHING CASE is critical for optimal performance and longevity:

1. Preparation: Clean the bore thoroughly and inspect for scoring or distortion.

2. Alignment: Ensure bore and pin axes are aligned to prevent edge loading.

3. Press-Fit: Use a hydraulic press for steady, controlled insertion—never hammer directly.

4. Lubrication: Inject OEM-grade grease through the port until it flows uniformly across the bushing surface.

5. Verification: Rotate the pin manually to confirm smooth movement and proper lubricant distribution.

Following these steps ensures the bushing achieves full seating and maximum wear resistance from day one.

Maintenance Schedule

• Re-grease every 250 hours (standard use)

• Re-grease every 100 hours (in muddy or abrasive conditions)

• Inspect clearance at each grease interval

• Replace if radial play exceeds 0.5 mm or surface scoring is visible

A properly maintained KBV14210 BUSHING CASE can exceed 20,000 working hours before requiring replacement.

Quality Control and Testing

All bushings from 3GEN Export’s OEM line undergo six stages of inspection:

1. Dimensional Check via Coordinate Measuring Machine (CMM)

2. Hardness Verification (HRC scale testing)

3. Surface Profile Inspection with contact profilometer

4. Load Simulation Testing under axial and radial stress

5. Lubrication Flow Validation through pressure tests

6. Final Visual Examination for micro cracks and surface defects

Each batch is traceable by lot number, ensuring quality consistency and accountability.

Field Performance Benefits

1. Reduced Downtime

Durable metallurgy and precise fitment dramatically reduce replacement frequency, keeping machines operational longer.

2. Improved Control and Precision

With minimal clearance and excellent concentricity, operators experience smoother motion in bucket and arm articulation.

3. Extended Component Lifespan

Protects pins and bores from metal-to-metal wear, reducing overall maintenance costs and machine depreciation.

4. High Load Endurance

Handles continuous dynamic loads in demanding environments such as quarries and urban construction sites.

5. Operator Comfort

Less vibration and noise mean more stable machine operation, improving safety and fatigue levels.
