Swing Gearbox Fit for Excavator Sumitomo SH350-5
The swing gearbox, also known as the swing drive, is a crucial component of excavators that helps to rotate the excavator cab and upper structure. Here are some of the key features and functions of our swing gearbox:
- Enables smooth and precise rotation of the excavator cab and upper structure
- Transfers power from the hydraulic motor to the excavator turntable
- Reduces wear and prevents damage to other components of the excavator
- Provides durability and reliability in harsh working conditions

Installation and Functionality
The swing gearbox is typically located on the back of the excavator's cab and is connected to the hydraulic motor. It works by receiving oil from the hydraulic system and using a planetary gear system to transfer torque to the swing pinion. This allows for smooth and precise rotation of the upper structure, even when under load.
Our swing gearbox is specifically designed to fit the Excavator Sumitomo SH350-5, providing a perfect match for this excavator model. Before purchasing, customers should ensure the following parameters:
| Parameter | Description |
|---|---|
| Excavator model | Ensure the swing gearbox is compatible with the specific excavator model |
| Weight and size | Make sure the swing gearbox can handle the weight and size of the excavator |
| Operating conditions | Consider the working environment and operating conditions to ensure optimal performance |

Signs of Replacement
There are various signs that indicate the need for a swing gearbox replacement:
- Unusual noises or vibrations during rotation
- Difficulty rotating the upper structure
- Inconsistent or jerky movement when rotating
- Leaking oil or damaged seal
