Precision Joining with Integrated Force Monitoring up to 60 kN
The Kistler NCF-H Servo Press System (Type 2151B) is a high-performance solution for precision joining and press-fit applications requiring forces up to 60 kN. Equipped with an integrated piezoelectric force sensor, the NCF-H provides accurate force measurement and real-time process monitoring to ensure consistent assembly quality and complete production traceability.
Its innovative hollow-shaft motor design delivers a compact footprint while maintaining generous stroke lengths of 200 mm (Size I) and 400 mm (Size II). The system can be mounted in virtually any orientation, including horizontal, vertical, angled, or inverted positions, providing exceptional flexibility for machine builders and automated manufacturing environments.
Capable of monitoring both push and pull operations, the NCF-H supports a wide range of joining and assembly applications while delivering the process data required for modern quality control and continuous improvement initiatives.
Key Features
Integrated Piezoelectric Force Sensor
The built-in force sensor continuously measures joining force throughout the process, enabling real-time quality monitoring and process validation.
Dual Measuring Range Technology
The NCF-H features a unique dual measuring range, allowing a single press to accurately perform both low-force and high-force applications.
Unlike conventional systems that sacrifice low-force accuracy when configured for higher loads, the NCF-H can switch between measurement ranges via PLC control. This allows manufacturers to use one press for multiple assembly operations while maintaining exceptional measurement accuracy across the entire force spectrum.
Benefits include:
- Increased measurement accuracy
- Greater process flexibility
- Reduced equipment requirements
- Support for mixed-product manufacturing
- Improved quality control at both low and high forces
Bidirectional Force Monitoring
Monitor and verify joining operations during both pressing and pulling movements, expanding application flexibility and process visibility.
Compact Hollow-Shaft Design
The hollow-shaft servo motor provides a compact overall footprint while maintaining high performance and long stroke capability.
Flexible Mounting Options
The NCF-H can be mounted:
- Horizontally
- Vertically
- At any angle
- Upside down
- Via wall or flange mounting

Benefits for Quality Engineers
100% Process Verification
Validate every assembly operation against predefined force and displacement criteria to ensure product quality and process consistency.
Early Defect Detection
Immediately identify:
- Missing components
- Incorrect parts
- Misalignment
- Incomplete insertion
- Damaged assemblies
before they proceed to downstream manufacturing stages.
Full Production Traceability
Capture force-displacement signatures and process data for every cycle, supporting quality documentation, compliance requirements, and customer audits.
Enhanced Statistical Process Control
Generate reliable process data for:
- SPC programs
- Cp/Cpk analysis
- Trend monitoring
- Continuous improvement initiatives
Reduced Scrap and Rework
Detect process deviations during assembly rather than after production, helping lower manufacturing costs and improve throughput.
Faster Root Cause Analysis
Historical force-displacement data provides engineers with valuable insight when diagnosing quality issues and implementing corrective actions.
Reduced Warranty Risk
By validating every joining operation, manufacturers can significantly reduce the risk of defective products reaching customers.
