As Southeast Asia continues to industrialize rapidly, Vietnam has emerged as one of the most promising markets for heavy machinery components—including slewing ring bearings (swing bearings).
Driven by infrastructure expansion, renewable energy investments, and industrial automation, Vietnam is creating strong demand for rotating equipment components used in construction machinery, cranes, wind turbines, and automated systems.
For global suppliers such as ZZ Slewing Bearing (Shanghai) Co., Ltd., this market presents significant export opportunities.
- Massive Infrastructure Investment Is Fueling Equipment Demand
Vietnam is undergoing one of the fastest infrastructure expansions in Southeast Asia.
The government has committed more than $25 billion to infrastructure projects, including highways, ports, rail networks, airports, and urban development programs.
Major projects include:
- Expressway and smart highway networks
- Metro systems in Hanoi and Ho Chi Minh City
- Airport expansions and logistics hubs
- Bridge construction and port modernization
These projects require large numbers of:
- crawler excavators
- tower cranes
- mobile cranes
- drilling rigs
- lifting equipment
All of these machines rely on slewing bearings as a critical component enabling rotational movement.
As a result, the demand for high-load capacity slew ring bearings is growing rapidly across Vietnam’s construction sector.
- Rapid Growth of Construction Equipment Market
Vietnam’s construction equipment market is projected to grow from 2,575 units in 2024 to nearly 4,900 units by 2030, with an annual growth rate exceeding 11%.
Excavators account for the largest share of equipment used in the country’s earthmoving and infrastructure projects.
Key international manufacturers active in Vietnam include:
- Komatsu
- Caterpillar
- Hitachi Construction Machinery
- SANY
- LiuGong
Each excavator, crane, or drilling machine requires slewing rings for upper structure rotation, making this industry a major consumer of large-diameter bearings.
- Vietnam Relies Heavily on Imported Machinery Components
Unlike countries with strong heavy-bearing manufacturing industries, Vietnam currently relies heavily on imported machinery and components.
Construction machinery in Vietnam is largely imported from:
- China
- Japan
- South Korea
- Europe
- the United States
This dependence creates opportunities for global manufacturers supplying:
- OEM slewing bearings
- replacement swing bearings
- large-diameter slewing rings
- customized heavy-duty bearings
For experienced manufacturers like ZZ Manufacturing, the Vietnamese market represents an attractive entry point due to strong equipment demand and limited local bearing production capacity.
- Renewable Energy Expansion Is Increasing Demand for Large Bearings
Vietnam is rapidly expanding its renewable energy sector as part of its national power development strategy.
By 2030 the country plans to significantly expand:
- solar energy capacity
- onshore wind power
- offshore wind projects
Total renewable energy capacity is expected to grow dramatically as Vietnam works toward its net-zero emissions goals and energy security targets.
Wind turbines require multiple large-diameter slewing bearings for:
- yaw systems
- pitch control mechanisms
- turbine orientation systems
This creates a long-term demand for high-precision bearings capable of operating in harsh offshore environments.
- Crane, Port, and Logistics Equipment Are Expanding
Vietnam’s rapid industrialization has also increased demand for:
- port cranes
- ship loaders
- container handling equipment
- gantry cranes
- offshore lifting systems
Urbanization in cities such as Hanoi, Ho Chi Minh City, and Da Nang has driven demand for tower cranes and heavy lifting equipment used in high-rise construction.
These machines rely on slewing rings to enable precise rotational movement under heavy loads, further expanding the market for high-quality bearings.
- Industrial Automation and Robotics Are Emerging Markets
Vietnam is becoming a major manufacturing hub for global companies, particularly in electronics, automotive, and industrial equipment.
Automation equipment increasingly used in Vietnamese factories includes:
- AGV robots
- automated storage systems
- robotic welding platforms
- rotating assembly tables
- packaging machinery
Compact slewing bearings and turntable bearings are widely used in these systems to enable smooth rotational movement with high precision.
This sector is expected to grow as Vietnam continues to attract foreign manufacturing investment.
- Replacement and Maintenance Demand
Slewing bearings typically operate under:
- heavy axial loads
- shock loads
- harsh outdoor environments
As a result, industries such as construction, mining, and energy require frequent replacement of worn bearings.
Vietnam’s growing fleet of excavators, cranes, and drilling rigs ensures a continuous aftermarket demand for replacement slew rings.
For suppliers, this creates recurring business opportunities through distributors and service companies.
