Main Technical Parameter

Key Features

High-Speed Production

Cycle Time: ≤10 s/set

The optimized production layout and synchronized servo-driven systems enable high-speed continuous operation while maintaining stable assembly quality.

Modular Fast Changeover

The production line adopts modular quick-change tooling, significantly reducing model changeover time.

Whole-line model changeover: approximately 3 hours / 3 operators

This design allows manufacturers to efficiently switch between different wheel hub bearing models while minimizing production downtime.

Fully Automatic Production

The entire production process is automatically connected from loading to unloading.

Loading Direction: Left → Right
Operators: 1–2 persons for the complete line

The automated material handling system ensures smooth and stable transfer of bearings between each process station.

Stable & Damage-Free Material Handling

Throughout the production process, bearings are transported and processed smoothly to minimize the risk of:

• Dents
• Scratches
• Collision damage
• Handling defects

From automatic loading through final unloading, the entire material flow is designed for stable, continuous and damage-controlled operation.

Intelligent Quality Control & Traceability

The third-generation wheel hub bearing assembly line integrates comprehensive inspection, data management and quality control functions throughout the production process.

Real-Time Process Monitoring

Critical production parameters can be monitored, recorded and evaluated, including:

• Pitch measurement
• Steel ball specification
• Calculated internal clearance
• Grease grade
• Grease injection quantity
• Press-fitting pressure
• Press-fitting displacement
• Press-fitting height
• Runout
• Angular clearance
• Negative clearance
• Assembly height
• Torque
• Vibration
• ABS testing results

Each inspection station provides visualized production data and statistical analysis.

SPC Data Management

Every inspection station is equipped with SPC statistical functions and production data storage.

Data Management Features

• Data retention for up to 6 months
• USB data export
• Production quantity statistics
• OK quantity statistics
• NG quantity statistics
• Measurement data recording
• Inspection result visualization
• NG reason identification
• Defect location identification
• Parameter modification time records

This enables manufacturers to establish a more complete production quality traceability system.

Intelligent NG Management

Each machine is equipped with a dedicated lockable NG bin and full-bin alarm.

The system provides a 1-to-1 correspondence between NG inspection data and the actual NG product, helping operators quickly identify and trace non-conforming products.

The equipment also includes standard reference part verification reminders, supporting consistent inspection accuracy during production.

Comprehensive Safety & Alarm System

The assembly line incorporates multiple levels of automatic monitoring and alarm functions.

The system can monitor and provide alarms for:

• Missing steel balls
• Missing components
• Abnormal press-fitting pressure/displacement
• Insufficient bolts
• Insufficient grease
• Low steel ball level
• Abnormal air pressure
• Servo motor overload
• Abnormal rotation speed
• Abnormal vibration/ABS testing conditions
• Equipment operation abnormalities
• NG product confirmation
• Safety door opening

This comprehensive alarm architecture helps operators identify abnormal conditions quickly and reduce production risks.

Advanced Inspection & Assembly Technology

The production line combines precision assembly, automated inspection and intelligent data management into one integrated manufacturing system.

Critical press-fitting stations continuously monitor pressure-displacement curves, allowing the system to identify abnormal press-fitting conditions during both intermediate and final positions.

The inspection system can automatically distinguish between OK and NG products, send non-conforming products to the corresponding NG lane, and record the inspection results for subsequent analysis and traceability.

Industrial Design & Safety Protection

The machine frame is manufactured using welded structural steel and aluminum alloy profiles, providing a rigid and stable platform for high-precision assembly.

Key design features include:

• Heavy-duty welded machine frame
• 80 × 80 mm structural square tubing
• Precision-machined 30 mm carbon steel base plate
• Aluminum alloy upper frame
• Transparent visual safety doors
• Protective acrylic covers
• Surface-treated structural and tooling components
• Hard chrome plating, black oxide or anodizing where required
• MC Nylon, POM and polyurethane materials for impact protection

The overall design combines industrial durability, precision and modern visual appearance.

Power & Utility Requirements

Electrical Power: AC 380 V, 50 Hz
Compressed Air: 0.4–0.6 MPa
Air Treatment: Oil mist filtration + automatic drainage system

PLC & Software Management

The PLC programs are fully commented to provide clear information for alarms and equipment status.

The control system provides clear visualization of:

• Equipment status
• Production information
• Inspection results
• OK / NG status
• Alarm information
• Process parameters
• Statistical data

Access to the PLC and HMI/PC programs is provided to the buyer after completion of the final payment, according to the agreed commercial terms.
