When purchasing industrial robots, many factories focus only on the robot itself while overlooking the critical role that spare parts play in ensuring stable production.

After long-term operation, key components such as gear reducers, cables, controllers, and teach pendants may experience wear or failure. Original manufacturer parts often come with high costs and long delivery times, while low-quality aftermarket parts may have poor compatibility and create additional risks of equipment damage.

With 15 years of experience in second-hand industrial robot solutions, FANCHENG ROBOT has established a standardized spare parts warehouse to provide customers with reliable, one-stop Robot Maintenance solutions.

This article explains common spare part replacement scenarios, purchasing considerations, and FANCHENG ROBOT’s comprehensive spare parts supply capabilities.

When Do Industrial Robots Need Spare Parts Replacement?

After continuous production operation, industrial robot components naturally experience wear over time. During routine inspections, factories should evaluate repair or replacement when the following situations occur:

1. Wear of Core Mechanical Components

Transmission components such as gear reducers, servo motors, robot joints, and mechanical arms may experience wear, resulting in abnormal noise, movement interruption, reduced accuracy, or decreased payload capacity.

2. Aging or Damage of Cables

Long-term bending and environmental exposure may cause signal cables to crack or break, leading to unstable communication, short circuits, or system alarms.

3. Control System Failures

Failures of controller boards, drives, or communication modules may cause frequent errors, system interruptions, or abnormal program execution.

4. Teach Pendant Malfunctions

A damaged teach pendant, including screen failure, button malfunction, or touch control issues, can prevent operators from programming and controlling the robot properly.

5. Regular Maintenance Requirements

According to robot maintenance schedules, consumable parts such as seals, batteries, and lubricants should be replaced regularly to prevent unexpected downtime.

Key Considerations When Purchasing Used Industrial Robot Spare Parts

1. Confirm Complete Robot Model Information

Different brands and even different models from the same brand may use different spare parts. Before purchasing, customers should provide:

• Robot brand
• Robot model
• Controller model
• Spare part number

This ensures accurate compatibility and avoids unnecessary returns or replacement delays.

2. Check Spare Part Condition and Avoid Low-Quality Refurbished Parts

Some low-cost spare parts on the market may contain hidden defects. Poor-quality components can cause secondary failures after installation.

Before purchase, spare parts should be professionally inspected to ensure reliable performance and immediate usability.

3. Technical Support Is Essential

Spare part replacement, installation, and commissioning may require professional technical knowledge. Choosing a supplier that provides troubleshooting guidance and technical support can significantly reduce maintenance risks.

4. Consider Long-Term Supply Stability

Small suppliers may not have stable inventory resources. For long-term robot maintenance, companies should choose suppliers with professional warehouses and continuous supply capabilities.
