FLENDER ATB-LOHER AG Product Lines We Repair
Our engineers are trained on the full FLENDER ATB-LOHER AG product range. Below are the major product families we service.
FLENDER SIMPLIFLEX Couplings
Flexible jaw couplings with integrated torque monitoring and condition sensors. Common issues include sensor signal loss, elastomer degradation detection failures, and misalignment-induced vibration sensor faults requiring recalibration.
FLENDER ARPEX Gearboxes
High-efficiency helical and bevel gearboxes for cement mills, sugar refineries, and mining conveyors. Repair focuses on bearing wear detection circuits, oil temperature sensor failures, and overload alarm electronics malfunction.
FLENDER DYNACHECK Monitoring Systems
Integrated condition monitoring and predictive maintenance electronics for rotating equipment. Common faults include accelerometer signal dropout, temperature probe open circuits, and CAN bus communication failures in mill drive systems.
FLENDER MAXXDYN Hard Disk Drive Units
High-torque gearbox assemblies for paper mills, steel plants, and wind power generators with embedded torque and speed control electronics. Typical repairs involve encoder interface faults, power supply regulation failure, and motor phase detection errors.
FLENDER MONOPLAN Helical Gearboxes
Compact modular gearboxes with integrated thermal and vibration monitoring for Indian sugar and cement industries. Sensor electronics failures, threshold calibration drift, and alarm relay sticking are frequent repair issues.

Common FLENDER ATB-LOHER AG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FLENDER ATB-LOHER AG equipment arriving at our workshop.
- ✓Temperature sensor open circuit or short condition — FLENDER RTD and thermocouple sensors in gearbox assemblies suffer corrosion and vibration-induced wiring disconnection, particularly in high-humidity environments like Indian sugar mills and coastal steel plants.
- ✓Vibration monitoring signal loss or false alarms — FLENDER accelerometer mounting looseness, piezo sensor degradation, and signal conditioning amplifier drift cause intermittent or persistent alarm activation in cement mill applications where dust ingress is common.
- ✓Coupling encoder output discontinuity — SIMPLIFLEX and other FLENDER couplings equipped with optical or magnetic encoders experience sensor gap variation and phototransistor contamination from airborne mill dust and moisture, causing intermittent shaft speed signal failure.
- ✓CAN bus or Modbus communication failure — FLENDER DYNACHECK monitoring systems experience CAN transceiver IC failures, shielded cable short circuits, and connector corrosion in Indian plant environments with poor cable routing or inadequate panel sealing.
- ✓Overload relay chatter and spurious shutdowns — Current transformer saturation, relay coil wear, and power supply ripple in FLENDER gearbox motor control circuits cause nuisance trips, especially under soft-start or VFD operation common in Indian sugar processing plants.
- ✓Slip ring or brush contact degradation in torque transducers — FLENDER SIMPLIFLEX coupling torque sensing slip rings and brushes deteriorate under continuous rotation and moisture exposure, particularly in mining and material handling applications across Indian industrial clusters.

Frequently Asked Questions — FLENDER ATB-LOHER AG Repairs
Do you repair FLENDER ATB-LOHER AG equipment anywhere in India?+
Yes. Synchronics repairs the complete FLENDER ATB-LOHER AG product range including SIMPLIFLEX couplings, ARPEX gearboxes, DYNACHECK monitoring systems, and all embedded electronics and sensors. We offer PAN-India pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, and all other industrial cities. All repairs are performed at our ISO-certified facility in Vadodara, Gujarat with 30+ year expertise in German industrial equipment.
What is the typical turnaround time for FLENDER gearbox sensor and control electronics repair?+
Standard FLENDER electronics repair turnaround is 5-7 working days including diagnostics, component replacement, recalibration, and full functional testing. Critical repairs for running mills and plants can be expedited to 48-72 hours with premium service charges. Synchronics maintains ready stock of common FLENDER sensor modules and replacement PCBs to minimize downtime.
How do you diagnose FLENDER DYNACHECK monitoring system faults in cement mill applications?+
FLENDER DYNACHECK systems are diagnosed using multi-channel data loggers to capture accelerometer signals, temperature probe outputs, and CAN bus messaging simultaneously. We perform FFT vibration analysis, thermal transient mapping, and protocol frame validation. Common cement mill issues like encoder signal dropout and temperature threshold drift are identified and corrected with full system recalibration and sensor replacement using original FLENDER components.
Can Synchronics calibrate FLENDER coupling torque sensors after repair?+
Yes. Synchronics possesses certified load cells and torque calibration rigs for FLENDER SIMPLIFLEX coupling transducers. Post-repair torque output is verified across the full 0-100% capacity range, with linearity and hysteresis certification documented and provided. This ensures your coupling torque measurements are accurate for predictive maintenance algorithms and overload detection in sugar mills and mining operations.
Do you stock original FLENDER ATB-LOHER AG spare parts and sensors?+
Synchronics maintains inventory of genuine FLENDER replacement sensors, coupling components, temperature probes, accelerometers, and common PCB modules. We source directly from FLENDER authorized distributors and can typically fulfill spare parts requests within 48-72 hours. For specialized or discontinued components, our engineering team identifies equivalent cross-supply parts certified for Indian industrial operating conditions.
How do I send my FLENDER ATB-LOHER AG unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a FLENDER ATB-LOHER AG drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on FLENDER ATB-LOHER AG repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your FLENDER ATB-LOHER AG unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
