FSG Product Lines We Repair
Our engineers are trained on the full FSG product range. Below are the major product families we service.
Planetary Gearbox Series
Compact single and multi-stage planetary gearboxes with ratios from 3:1 to 1000:1. Common repairs include internal gear tooth fracture, planet bearing wear, output shaft runout, and seal degradation causing lubricant loss.
Helical Gear Motor Units
Medium-torque helical gearboxes paired with AC and DC motors for packaging, printing, and assembly line applications. Typical faults include gear tooth pitting, motor brush wear, speed loss, and misalignment-induced vibration.
Servo Motor-Gearbox Assemblies
Precision integrated systems for robotics and CNC machinery combining servo motors with low-backlash gearboxes. Repairs address encoder malfunction, backlash increase due to gear wear, and thermal management issues in high-duty applications.
Right-Angle Bevel Gearboxes
90-degree drive transmission for space-constrained installations in packaging and textile machinery. Common faults include bevel gear scoring, output bearing preload loss, and input-output shaft misalignment.
Direct-Drive Motor-Gearbox Modules
Sealed, lubricated assemblies for food processing and pharmaceutical equipment requiring washdown resistance and low-speed high-torque delivery. Failures include seal degradation, internal corrosion, and motor winding insulation breakdown.

Common FSG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FSG equipment arriving at our workshop.
- ✓Planetary gear tooth fracture and spalling — FSG planetary gearboxes operating beyond rated torque or under shock loads in automotive assembly lines experience accelerated wear. Hardened tooth surfaces fracture under repeated overload, generating metallic debris that accelerates secondary failures.
- ✓Output shaft bearing preload loss and runout — Extended operation without proper lubrication or contamination ingress causes FSG output bearings to develop excessive play. Ball and roller bearings degrade, increasing radial runout that affects connected equipment precision and causes vibration.
- ✓Seal leakage and lubricant loss — Degraded elastomer seals in FSG gearboxes, particularly in high-temperature environments (printing presses, textile machinery), allow synthetic gear oil to escape. Loss of lubrication film leads to rapid gear and bearing deterioration.
- ✓Encoder malfunction and position feedback loss — FSG servo motor-gearbox assemblies integrate rotary encoders for closed-loop control. Connector corrosion, wiring insulation damage, or encoder disk misalignment in high-vibration environments disable position feedback, causing servo errors and loss of motion synchronization.
- ✓Helical gear tooth pitting and contact pattern degradation — FSG helical gearboxes in printing and packaging machinery experience cyclic Hertzian stressing. Inadequate lubrication film thickness or misalignment concentrates contact stress, initiating micro-pitting that propagates into large spalls under continued operation.
- ✓Motor winding insulation breakdown in sealed assemblies — FSG direct-drive motor-gearbox modules used in washdown environments accumulate moisture and chemical vapors inside sealed housings. Motor winding insulation deteriorates, causing phase-to-phase or phase-to-ground faults and complete drive failure.

Frequently Asked Questions — FSG Repairs
Do you repair FSG gearboxes anywhere in India?+
Yes. Synchronics repairs the complete FSG product range — planetary gearboxes, helical gear motors, servo motor-gearbox assemblies, bevel gearboxes, and sealed direct-drive modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other industrial cities. All repairs are performed at our main facility in Vadodara, Gujarat, with 180+ experienced engineers and full technical documentation.
What is the typical turnaround time for FSG gearbox repair at Synchronics?+
Standard FSG repairs (seal replacement, bearing reconditioning, gear assessment) take 7-10 working days including testing and verification. Complex repairs requiring custom machining or encoder recalibration extend to 12-14 days. Emergency rush service is available for critical production equipment; contact our service coordinator for expedited scheduling.
Can Synchronics repair FSG servo motor-gearbox assemblies with encoder integration issues?+
Yes. Our engineers specialize in FSG servo system diagnostics, including encoder signal verification, position feedback testing, and closed-loop control troubleshooting. We repair or replace rotary encoders, recalibrate zero-point offsets, test servo response, and supply detailed commissioning documentation. This expertise supports Indian robotics and CNC equipment manufacturers.
Do you stock OEM FSG replacement parts or use compatible alternatives?+
Synchronics prioritizes OEM FSG components for critical repairs — bearings, seals, gears, and encoders sourced through authorized channels to maintain equipment performance and warranty compliance. For obsolete components or bulk repairs, we recommend cost-effective alternatives meeting FSG material and dimensional specifications. All part selections are documented in repair reports.
How does Synchronics ensure repaired FSG gearboxes meet original performance specifications?+
Every FSG repair includes comprehensive testing: bearing preload verification, shaft runout measurement using dial indicators, gear contact pattern analysis, torque load testing, and encoder signal validation where applicable. We document all measurements against FSG technical data sheets and provide a detailed test report. Sealed units undergo pressure testing to confirm lubrication integrity.
How do I send my FSG 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 FSG 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 FSG 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 FSG 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.
