Specialized Crankshaft Engineering

• Crankshaft-specific construction– Engineered exclusively for engine overhaul shops with capability to balance various crankshaft types including complete assemblies with flywheel and pulley attachments. The machine accommodates V-type crankshafts with attached bobweights, handling the complex geometry and mass distribution unique to automotive and industrial engine applications.
• High-precision crankshaft measurement– Achieves exceptional balancing accuracy of 0.4 g·mm/kg (0.4 µm) specifically calibrated for crankshaft tolerances and engine performance requirements. This precision level ensures optimal engine smoothness and bearing life extension critical for professional engine rebuilding operations.
• Comprehensive crankshaft size range– Accommodates crankshafts weighing 3-300 kg with journal diameters from 30-180 mm and center distances of 150-1350 mm, covering passenger vehicles through heavy-duty industrial engines. The versatile sizing ensures compatibility with virtually all crankshaft configurations encountered in engine overhaul facilities.

Advanced Precision Construction

• Monolithic support and base design– Rigid one-piece construction eliminates vibration losses during balancing by minimizing oscillation system elements, crucial for accurate crankshaft measurement with inherent mass asymmetries. The monolithic approach provides superior structural integrity compared to assembled designs for consistent long-term accuracy.
• “Exact Barrel”® roller technology– Features specially designed rollers assembled with precision bearings and utilizing patented grinding technology for superior contact accuracy with crankshaft journals. This advanced roller design minimizes measurement errors caused by surface variations and ensures consistent support throughout the balancing process.
• MICRO-TUNING® axial compensation– Proprietary technology automatically eliminates effects of axial misalignment during rotation, critical for crankshafts where perfect alignment is difficult to achieve. This system maintains measurement accuracy despite the inherent setup challenges presented by crankshaft geometry and weight distribution.

Integrated Correction Capabilities

• On-machine drilling module– Integrated drilling system enables unbalance correction by material removal from counterweights without crankshaft removal from the machine. This capability significantly increases productivity by eliminating setup time while maintaining precise correction placement relative to measurement reference points.
• Adjustable roller block height– Accommodates crankshafts with varying journal diameters and enables precise centering during machine setup, essential for accurate measurement of complex crankshaft geometries. The adjustment capability ensures optimal support contact regardless of crankshaft design variations.
• Large unbalance handling capability– Designed to measure and correct large initial unbalances typical of damaged or heavily worn crankshafts without machine damage or measurement degradation. This robust capability is essential for engine overhaul applications where crankshafts may have significant existing unbalance conditions.

Optimized Drive and Control Systems

• Variable frequency belt drive– 2.2 kW motor with frequency inverter provides smooth acceleration and infinitely variable speed control from 300-1500 rpm, optimized for crankshaft balancing requirements. The power reserve reduces cycle times while maintaining precise speed regulation throughout the measurement process.
• LONG STROKE® belt design– Patented belt drive system accommodates crankshafts of varying lengths using only two drive belts, providing reliable power transmission regardless of crankshaft configuration. This design eliminates the need for multiple belt configurations while ensuring consistent drive engagement.
• Low resonance frequency operation– Support system designed with low natural resonance frequency enables accurate balancing at reduced rotational speeds, important for heavy crankshafts where high-speed operation may be impractical. This feature enhances both safety and measurement quality for large engine components.

Engine Shop Integration Features

• Compact engine shop footprint– 1600 mm base length with maximum 1300 mm rotor diameter clearance provides efficient space utilization typical of engine overhaul facilities. The compact design maximizes functionality while fitting into standard automotive service bay configurations.
• Real-time measurement display– PAK-1 balancing system with industrial PC and touch screen provides continuous monitoring of unbalance behavior during measurement, enabling immediate assessment of crankshaft condition. The real-time feedback accelerates decision-making for correction procedures.
• Modular configuration options– Supports various drive configurations including axial drive with cardan shaft for high-torque applications and combined drive systems for shops handling diverse engine types. The modular approach allows customization for specific engine overhaul requirements while maintaining standardized operation procedures.

Professional Service Optimization

• External vibration immunity– Advanced isolation system provides high protection against shop floor vibrations and measurement disturbances common in automotive service environments. This immunity ensures consistent accuracy despite the variable conditions typical of engine overhaul facilities.
• Operator-friendly calibration– Machine setup and calibration procedures designed for operator execution without specialized technical knowledge, reducing dependency on external service technicians. This self-service capability maintains productivity and reduces operational costs in busy engine overhaul operations.
