4443885
Product Name: Bushing / H-Link Closed End Bushing / Split Bushing / Connecting Rod Closed End Bushing
Part Number: 4443885
Brand/Compatibility: Suitable for John Deere / Hitachi
Type: H-Link Closed End Bushing / Linkage/H-Link Bushing (commonly used in the connection between the stick and H-link, a high-load, wear-prone part)
Weight: Approximately 1.11kg
Material: High-strength alloy steel (such as 40Cr or similar), carburized, quenched, and precision machined, possessing high wear resistance, compressive strength, and fatigue resistance, with high surface hardness, suitable for heavy-duty excavation environments.
Function and Location:
- Primarily installed at the connection point between the excavator stick/dipper and the H-Link, linkage mechanism, or bucket.
- Provides support, shock absorption, wear resistance, and maintains alignment; it is a critical rotating/swinging component in the working device.
- Prone to wear after prolonged heavy-duty operation, leading to increased clearance, abnormal noise, oil leakage, or loose linkage. It is recommended to inspect/replace it along with the matching pin, oil seal, and dust cover.
- Use a special press-fitting tool during installation to ensure alignment and apply an appropriate amount of grease; simultaneously replace related seals to prevent rapid wear. Professional technician operation is recommended.
