Description
The BZZ1-160C Steering Unit is a high-reliability, cost-effective hydrostatic steering device, designed specifically for medium and heavy-duty machinery.
It belongs to the classic BZZ1 series, optimized with the “C” type structure to enhance compatibility and operational stability, making it a preferred choice for hydraulic steering systems that demand precision and durability.

Overview of the BZZ1-160C Series Hydraulic Steering Unit

As a core product in the BZZ1 series, the BZZ1-160C Series integrates a rotary valve and a gerotor meshing pair, adopting advanced hydrostatic transmission technology.
Unlike traditional mechanical steering systems,  it requires no mechanical linkage between the steering wheel and steered components,  simplifying installation and reducing equipment weight.
The model designation “160” refers to its standard displacement of 160 ml/r,  which is perfectly matched to the steering demand of medium and heavy-duty equipment.
The “C” suffix represents its optimized design—improved sealing performance, enhanced corrosion resistance, and better adaptability to harsh working environments.

Key Features of the BZZ1-160C Series

The BZZ1-160C Series stands out for its practicality and reliability, with features tailored to meet the daily operational needs of industrial machinery.
First, it offers sensitive and effortless steering. The unit’s internal hydraulic structure ensures that the steering force is evenly distributed, reducing operator fatigue even during long hours of continuous operation.
Besides, it supports emergency manual operation. In the event of a power failure or oil pump malfunction, the operator can easily switch to manual steering mode with minimal torque, ensuring equipment safety and operational continuity.
In addition, it boasts excellent sealing and durability. The optimized “C” type structure uses high-quality sealing components and corrosion-resistant materials, preventing oil leakage and extending the unit’s service life in dusty, wet, or high-temperature environments.
Last but not least, it has wide compatibility. The BZZ1-160C Series can be seamlessly matched with most standard hydraulic pumps and steering cylinders, making it easy to install and replace in existing equipment.

Working Principle of the BZZ1-160C Series

The working principle of the BZZ1-160C Series is straightforward, relying on hydrostatic pressure to transmit steering force without mechanical connection.
When the operator turns the steering wheel, it drives the rotary valve inside the unit to rotate. This rotation controls the direction of hydraulic oil flow from the supply pump, guiding the oil into the left or right cavity of the steering cylinder.
The oil pressure pushes the piston of the steering cylinder, driving the steered wheels to turn. The displacement of the gerotor meshing pair is proportional to the steering wheel’s rotation angle, ensuring precise control of the steering angle every time.

Applications of the BZZ1-160C Series Hydraulic Steering Unit

With its reliable performance and wide compatibility, the BZZ1-160C Series is widely used in various fields that require hydraulic steering systems.
It is commonly applied to construction machinery,  such as wheel loaders, road rollers,  and small excavators. These devices rely on the unit’s sensitive steering to improve work efficiency on construction sites.
Agricultural machinery is another key application area—tractors, harvesters, and agricultural loaders all benefit from the BZZ1-160C’s durable and labor-saving design. It also suits forestry machinery, mining auxiliary equipment, and light marine vessels, meeting diverse steering needs across industries.

Why Choose the BZZ1-160C Series?

Choosing the BZZ1-160C Series means choosing a balance of performance, reliability, and cost-effectiveness—ideal for businesses looking to optimize their equipment’s steering system.
Compared with similar products, it offers better adaptability to harsh working conditions, lower maintenance costs, and easier installation. Its emergency manual steering function also adds an extra layer of safety, reducing operational risks.
Whether you need to replace an old steering unit or equip new machinery, the BZZ1-160C Series Hydraulic Steering Unit delivers consistent performance and long-term value.
