Precision-Engineered Bushing for CASE Heavy Machinery

The KBV1357 BUSHING CASE is a high-strength, wear-resistant component designed to deliver reliable performance in the harsh operating conditions typical of construction, quarrying, and excavation. Manufactured to OEM standards by 3GEN Export, this bushing ensures seamless fitment, exceptional durability, and extended service life across a wide range of CASE Heavy Machinery models.

Bushings are critical to the movement and balance of mechanical joints. The BUSHING CASE KBV1357 acts as the protective interface between moving metal parts, minimizing friction, absorbing shock, and maintaining structural stability under dynamic loads. Whether installed in loader arms, pivot joints, or boom linkages, it sustains the machine’s precision and responsiveness even under constant vibration and heavy-impact cycles.

Technical Specifications and Features

Material and Surface Treatment

• Material: Premium alloy steel with high carbon content for superior hardness and tensile strength.

• Surface Finish: Precision-ground with fine tolerance (Ra ≤ 0.8 µm) to reduce friction and heat buildup.

• Heat Treatment: Induction-hardened raceways for maximum resistance to wear and fatigue.

• Coating: Anti-corrosion layer applied to protect against rust and contaminants.

The high-grade steel construction provides the KBV1357 BUSHING CASE with outstanding mechanical integrity. Each piece undergoes CNC machining followed by controlled heat treatment to achieve uniform hardness. This combination enhances fatigue strength while maintaining flexibility to resist cracking under sudden load shifts.

Dimensional Accuracy

• Inner Diameter (ID): 55 mm ± 0.02 mm

• Outer Diameter (OD): 70 mm ± 0.02 mm

• Width: 45 mm ± 0.02 mm

• Weight: 1.28 kg

The precise tolerances ensure a perfect press-fit assembly with shafts and housings. Dimensional integrity reduces misalignment and uneven wear, contributing to smoother operation and lower vibration levels throughout the machine structure.

Performance and Durability

• Dynamic Load Capacity: > 60 kN

• Operating Temperature Range: −40 °C to +180 °C

• Lubrication: Internal grease channel and oiling hole for consistent lubrication flow.

• Service Life: Extended by 25–30 % compared to standard bushings under identical load conditions.

These performance metrics highlight the KBV1357 BUSHING CASE as an advanced solution for equipment operators seeking reliability, precision, and cost-efficiency in demanding field environments.

Function within the Machine

The KBV1357 BUSHING CASE functions as the pivoting bearing surface in moving joints such as:

• Boom and stick pivot connections

• Bucket link mechanisms

• Hydraulic cylinder mount points

• Loader arm hinge sections

• Chassis articulation joints

In each of these applications, it provides the necessary clearance and support for smooth, controlled motion, helping the equipment maintain alignment and reduce mechanical stress over long operation cycles.

Engineering Advantages

1. Superior Load Distribution

The internal contour of the KBV1357 BUSHING CASE is precision-shaped to spread forces evenly across the contact surface. This minimizes local stress peaks and prevents premature deformation.

2. Friction Reduction

High-grade machining and micro-polished surfaces reduce metal-to-metal contact. When properly lubricated, the friction coefficient remains below 0.05, resulting in smoother motion and lower energy loss.

3. Extended Lifespan

Through a combination of precision manufacturing and advanced heat treatment, the service life is significantly longer than aftermarket alternatives, reducing downtime and total ownership cost.

4. Noise and Vibration Control

By maintaining precise clearances and consistent lubrication, the bushing reduces rattling and mechanical vibration — a key factor for operator comfort and machine longevity.

5. Environmental Protection

The anti-corrosive coating shields the metal surface from water, dust, and mud ingress, ensuring optimal operation even in wet or abrasive conditions typical of construction sites.

Installation and Maintenance

Proper installation of the KBV1357 BUSHING CASE is essential for ensuring maximum performance.

Installation Guidelines

1. Clean the housing and shaft thoroughly to remove debris or old grease.

2. Apply light film of oil or assembly grease to the inner surface before press-fitting.

3. Align the grease hole of the bushing with the lubrication channel of the machine.

4. Press the bushing using a hydraulic tool — never hammer directly.

5. After installation, perform initial greasing to ensure proper lubricant distribution.

Maintenance Tips

• Re-lubricate every 250 operating hours under standard conditions, or every 100 hours in harsh environments.

• Inspect bushing wear periodically by measuring clearance between shaft and inner surface.

• Replace when wear limit reaches 0.5 mm to prevent misalignment and vibration.

• Always use OEM-grade grease compatible with the material specifications.

By following these guidelines, operators can maximize the service life of their equipment and maintain factory-level efficiency.
