BONFIGIGLIOLI ENGINEERING Product Lines We Repair
Our engineers are trained on the full BONFIGIGLIOLI ENGINEERING product range. Below are the major product families we service.
Helical Gearmotors (AK, AKM, AK Right Angle)
Compact, efficient single-stage and multi-stage helical gearmotors used in conveyor drives, mixer applications, and material handling. Common repairs include bearing noise, oil seal leakage, and motor coupling failures under overload conditions.
Planetary Gearmotors (P, PL, PLF)
High-torque planetary reducers delivering precise speed reduction in compact form for hoists, press feeds, and indexing applications. Repair focus: planet gear wear, ring gear cracking, and internal seal degradation under shock loads.
Heavy-Duty Bevel Gearmotors (C, CM, W)
Right-angle bevel drive units for cement mills, pulp digesters, and mining equipment where 90-degree power transmission is essential. Common faults: bevel gear tooth spalling, thrust bearing wear, and oil degradation in high-temperature environments.
Torque Limiters and Safety Couplings
Slip-ring and spring-loaded torque limiters protecting downstream machinery from shock loads, jamming, and sudden stalls. Repairs involve slip-ring resurfacing, spring tension calibration, and bearing replacement.
In-Line Reducers (SH, SVT, SVP)
Shaft-mounted and in-line helical reducers for belt-drive and direct-drive applications in conveyor systems and crushers. Typical issues: input seal leakage, output flange crack, and internal corrosion from moisture ingress.

Common BONFIGIGLIOLI ENGINEERING Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BONFIGIGLIOLI ENGINEERING equipment arriving at our workshop.
- ✓Helical gear tooth pitting and micropitting — Extended operation under overload without adequate oil cooling, or use of low-viscosity lubricant in high-ambient Indian factory conditions. Contaminated oil particles accelerate tooth surface fatigue.
- ✓Oil seal and breather leakage — Bonfiglioli gearbox vents can clog with dust in Indian cement, flour, and sugar facilities, creating internal pressure that ruptures primary and secondary seals. Poor maintenance hygiene accelerates failure.
- ✓Bearing noise, grinding, and excessive vibration — Deep-groove ball and roller bearings in Bonfiglioli reducers wear under shock loads from sudden motor starts, jamming events, or misalignment in Indian paper mills and sugar extraction plants. Contaminated lubricant accelerates spalling.
- ✓Input or output shaft cracking and misalignment — Coupled motor vibration, pulley belt overtension, or impact loads from chain drive systems in Indian crushers and mills cause shafts to fatigue-crack near keyways or at step shoulders. Cumulative bending stress from unbalanced loads aggravates failure.
- ✓Motor coupling bolt loosening and wear — Bonfiglioli gearmotor input couplings (flexible jaw, elastomeric, or rigid) vibrate loose under continuous duty in Indian textile machinery and conveyor networks. Elastomer elements degrade in high-humidity coastal plants and high-temperature foundries.
- ✓Planetary gear carrier and ring gear cracking — Bonfiglioli compact planetary reducers under sustained overload in Indian hoisting and press applications develop cracks in the aluminum alloy carrier or hardened ring gear due to stress concentration and fatigue cycling.

Frequently Asked Questions — BONFIGIGLIOLI ENGINEERING Repairs
Do you repair Bonfiglioli Engineering equipment anywhere in India?+
Yes. Synchronics repairs the full Bonfiglioli Engineering product range — helical gearmotors, planetary reducers, bevel drives, torque limiters, and in-line reducers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. Single facility in Vadodara, Gujarat with 180+ engineers and modern test rigs for gearbox load validation.
What is the typical turnaround time for Bonfiglioli gearmotor repair?+
Standard turnaround is 10-15 working days from receipt. Complex jobs involving shaft replacement, bearing rebuild, or core exchanges may extend to 20 days. Synchronics offers express repair (5-7 days) for critical production motors. All repairs include pressure testing, torque verification, and no-load run-in before shipment. We maintain a stock of common Bonfiglioli spare parts to minimize delays.
My Bonfiglioli gearbox is leaking oil from the input seal. Can it be repaired without full disassembly?+
Seal leakage requires removal of the motor and partial disassembly to access the seal chamber. Synchronics replaces the primary input seal, inspects the shaft for scoring or damage, installs a backup seal, and upgrades the breather to prevent future pressure-induced leaks. We do not perform temporary patches; OEM-standard repairs only.
Do you stock Bonfiglioli replacement parts and gears?+
Synchronics maintains stock of high-demand Bonfiglioli helical gears, bearings, seals, and couplings. For less common parts (ring gears, planetary carriers, specialized shafts), we source directly from Bonfiglioli distributors or manufacture per OEM specification using CAD drawings. Lead time for custom gears is typically 5-7 days.
Can Synchronics repair Bonfiglioli gearmotors used in abrasive cement and sugar mill environments?+
Yes. Synchronics has extensive experience restoring Bonfiglioli reducers from cement mills, sugar factories, and flour mills across India. We address dust and moisture contamination, replace corroded fasteners, upgrade seals for harsh environments, and apply additional protective coatings on shafts. All repairs meet or exceed OEM specifications for industrial duty.
How do I send my BONFIGIGLIOLI ENGINEERING 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 BONFIGIGLIOLI ENGINEERING 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 BONFIGIGLIOLI ENGINEERING 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 BONFIGIGLIOLI ENGINEERING 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.
