GBG Product Lines We Repair
Our engineers are trained on the full GBG product range. Below are the major product families we service.
GBG Geared Motor Units
Helical and spur geared motor assemblies for continuous duty industrial applications. Common issues include bearing wear, seal degradation, oil contamination, and coupling misalignment leading to vibration and noise.
GBG Speed Reducer / Gearbox Electronics
Integrated control modules and sensors for variable-speed geared drives. Failures often stem from moisture ingress, connector corrosion, and firmware glitches in encoder feedback circuits.
GBG Shaft Couplings and Elastomeric Elements
Flexible couplings and damping sleeves used in GBG motor-to-load interfaces. Wear, elastomer hardening, and eccentricity are primary failure modes affecting vibration and torque transmission.
GBG Brake Systems for Vertical / Horizontal Loads
Spring-applied solenoid brakes integrated into GBG motor housings. Common faults include brake slip, solenoid coil burnout, and spring fatigue, especially in Indian cement and conveyor applications.
GBG Thermal and Vibration Monitoring Sensors
Embedded temperature sensors and vibration transducers for predictive maintenance. Issues include loose sensor connections, signal conditioning failures, and calibration drift in high-humidity Indian factory environments.

Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common GBG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GBG equipment arriving at our workshop.
- ✓GBG Gearbox Oil Oxidation and Acid Formation — Heavy industrial duty in Indian heat and humidity causes accelerated oil degradation. Contaminants from seal failure and moisture ingress form corrosive acids that pit gear teeth and bearing races.
- ✓GBG Coupling Elastomer Hardening and Torsional Stiffness Loss — Tropical UV exposure, temperature cycling, and ozone in Indian industrial areas cause rubber elastomers in GBG flex couplings to harden. This reduces damping and increases shock loads on bearings and gears.
- ✓GBG Brake Solenoid Coil Open Circuit or Winding Failure — Moisture ingress through corroded connector pins and thermal cycling cause insulation breakdown in brake solenoid coils. Indian humidity accelerates corrosion if drainage holes are blocked by dust.
- ✓GBG Encoder Signal Dropout and Feedback Loss — Corroded encoder cable connectors, water ingress into sensor heads, and EMI from adjacent VFDs cause intermittent or complete loss of encoder feedback signal in GBG variable-speed drives.
- ✓GBG Bearing Cage Fracture and Spalling Under High Radial Load — Misalignment, inadequate lubrication in hot Indian climates, and bearing preload drift cause accelerated fatigue spalling. Cage fracture follows, leading to sudden motor jam and coupling shear.
- ✓GBG Temperature Sensor NTC Thermistor Drift or Open Circuit — Exposure to moisture, vibration-induced solder joint cracking, and thermal cycling in Indian factory conditions cause NTC thermistor sensors to drift or fail open, disabling thermal protection.

Frequently Asked Questions — GBG Repairs
Do you repair GBG equipment anywhere in India?+
Yes. Synchronics repairs the full GBG product range — geared motors, speed reducers, brake systems, couplings, and control electronics. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nagpur, and all other cities. Same professional repair facility in Vadodara, Gujarat. Typical turnaround is 5-7 working days.
What is the most common GBG gearbox failure in Indian cement plants?+
Oil oxidation and acid formation are the leading cause of GBG gearbox failure in hot, humid Indian cement mills. Dust infiltration, high ambient temperature, and heavy continuous duty accelerate oil breakdown, causing gear pitting and bearing failure. Synchronics performs oil analysis and full internal flushing to reverse early-stage damage. We recommend annual oil sampling and drain-interval reduction in tropical climates.
Can Synchronics source and fit OEM spare parts for GBG motors?+
Yes. Synchronics maintains direct supply relationships for GBG gearbox seals, bearings, brake components, and elastomer couplings. For obsolete or long-lead parts, we source verified industrial-grade equivalents and thoroughly test them. Lead time is typically 3-5 days within India. All parts carry warranty and are fitted with precision alignment and balancing.
How do you test GBG brake systems after repair?+
Synchronics tests GBG spring-applied solenoid brakes on our dedicated test stand, measuring coil current draw, holding torque, and engagement/release time. We verify brake slip under rated load, confirm solenoid pull-in at nominal voltage, and perform thermal cycling to confirm reliability. All brakes are tested at full load before dispatch.
What is the typical cost of GBG gearbox bearing replacement in India?+
Bearing replacement cost depends on gearbox size, bearing grade, and accessibility. For typical industrial GBG units (GB3-GB9 range), bearing replacement ranges INR 8,000-25,000 including labor, alignment, and testing. Synchronics offers transparent quote within 24 hours of receiving your unit. Many Indian manufacturers find preventive bearing replacement cheaper than emergency downtime.
How do I send my GBG 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 GBG 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 GBG 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 GBG 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.
