Synchronics repairs the complete BISON gearbox and drive portfolio including their helical, bevel, worm, and planetary gear units. Our 30+ years of experience with German precision engineering means we diagnose bearing wear, gear tooth degradation, seal failures, and coupling misalignment—issues endemic to BISON systems running 24/7 in Indian mills and factories. We stock OEM-equivalent components and perform precision alignment to restore BISON equipment to original performance specifications.

BISON Product Lines We Repair
Our engineers are trained on the full BISON product range. Below are the major product families we service.
BISON Helical Gearboxes
Single and multi-stage helical units delivering high torque with minimal noise. Common repairs include worn gear teeth, bearing seizure from contaminated lubricant, and output shaft seal leakage causing oil loss and subsequent gear damage.
BISON Planetary Gear Units
Compact, coaxial planetary reducers for high-speed input applications. Typical failures involve sun gear spalling, planetary bearing degradation from inadequate preload, and carrier wear—all addressable through precision reboring and component replacement.
BISON Worm Gear Reducers
Self-locking worm drive units for vertical lift and positioning. Failure modes include worm shaft bending under overload, bronze worm wheel scoring, and bearing preload loss leading to axial play and noise.
BISON Bevel Gearboxes
Angle-drive units with spherical bevel gears for right-angle power transmission. Common issues are bevel gear tooth fracture, pinion bearing failure, and output flange bearing play—requiring skilled reboring and precision assembly.
BISON Shaft-Mounted Reducers
Direct-flange designs eliminating intermediate coupling and reducing assembly points. Typical faults include motor flange cracking, output bearing wear from unbalanced pulley loads, and oil leakage at housing-to-motor interface.
BISON Torque Limiter Couplings
Overload protection devices integrated into BISON drive packages. Slip and disconnect faults stem from worn friction discs, spring deterioration, and calibration drift—fixed through component replacement and torque re-calibration.

Common BISON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BISON equipment arriving at our workshop.
- ✓Helical gear tooth pitting and spalling — BISON gearboxes operating under sustained overload or with contaminated lubricant develop micropitting on gear flanks, which propagates into macroscopic spalls. In Indian textile mills running 24/7, inadequate filtration accelerates this failure mode dramatically.
- ✓Output shaft bearing preload loss and axial play — BISON planetary and helical units rely on precise bearing preload to maintain gear mesh accuracy. Thermal cycling in Indian foundry and steel mill environments causes spring relaxation and bearing race wear, introducing backlash and noise.
- ✓Oil seal and gasket leakage at housing joints — BISON housings experience vibration-induced separation and thermal stress. Seals degrade from oxidized oil, contamination ingress, and inadequate re-torquing during prior servicing—common in Indian cement and sugar plants where dust infiltration is severe.
- ✓Worm shaft deflection and bending under vertical load — BISON worm reducers in vertical hoist applications experience cantilever bending stress. Undersized bearings, insufficient preload, and shock loads from jerky motor starting (common with older VFD installations in India) accelerate shaft bending and fatigue cracking.
- ✓Planetary carrier wear and increased radial play — BISON planetary gear units subject to sustained torque ripple or misalignment develop wear grooves in the carrier bores where planetary gear pins rotate. High-speed conveyor and extruder drives in Indian food processing see accelerated carrier wear due to thermal growth and bearing preload relaxation.
- ✓Coupling misalignment and vibration-induced bearing failure — BISON gearboxes coupled to motors via flexible couplings often suffer misalignment after motor or gearbox repositioning. Indian field technicians frequently under-torque coupling bolts or neglect re-alignment after maintenance, causing excessive radial and axial bearing loads within BISON units.

Frequently Asked Questions — BISON Repairs
Do you repair BISON gearboxes anywhere in India?+
Yes. Synchronics repairs the full BISON gearbox and coupling portfolio across India. We offer PAN-India door pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Jaipur, Kolkata, and smaller industrial hubs. All repairs are performed at our Vadodara, Gujarat facility with 30+ years of German precision engineering expertise. Turnaround is typically 5-7 working days depending on complexity.
What is the cost of repairing a BISON helical gearbox versus buying new?+
BISON gearbox repair typically costs 35-50% of replacement cost depending on damage extent. Bearing and seal kits alone run 8,000-15,000 INR; full bearing sets plus gear replacement range 25,000-60,000 INR. For Indian manufacturers running high-utilization plants, repair ROI is achieved within 6-12 months through restored uptime. Synchronics provides free diagnostic assessment and written repair quote—call us for your specific BISON model and failure symptoms.
Can you repair BISON planetary gearboxes with broken sun gears or spalled planets?+
Yes, absolutely. Synchronics is one of India's few repair shops equipped to re-machine BISON planetary carriers and replace sun/ring gears and planet gears. We hold precision grinding equipment and stock replacement gear blanks in common BISON modules (32, 64, 120, 200 cc). We also perform planetary bearing preload re-calibration post-assembly. Typical sun gear replacement repair costs 18,000-35,000 INR and takes 7-10 days with full testing.
Does BISON gearbox repair include re-alignment and bearing preload verification?+
Yes. Every BISON repair at Synchronics includes precision alignment testing using laser equipment (motor-gearbox runout checked to 0.05 mm), bearing preload measurement with calibrated gauges, and full no-load rotation testing. We document all measurements on a service report so your maintenance team has a baseline for future inspections. This prevents repeat failures from misalignment—a leading cause of premature BISON gearbox bearing wear in Indian industrial environments.
What is Synchronics' warranty on BISON gearbox repairs?+
Synchronics offers a 12-month parts and labor warranty on all BISON gearbox repairs. We cover bearing failure, seal leakage, and gear tooth breakage under normal operating loads. Warranty excludes damage from contaminated oil, extreme overload, or unauthorized modification. We recommend annual preventive oil sampling and bearing preload checks—Synchronics provides this service at minimal cost to keep your BISON equipment performing reliably across Indian manufacturing seasons and thermal cycles.
How do I send my BISON 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 BISON 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 BISON 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 BISON 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.
