ARONSON Product Lines We Repair
Our engineers are trained on the full ARONSON product range. Below are the major product families we service.
Air-Engaged Clutches (AC Series)
Pneumatically actuated friction clutches used for torque transmission in printing, converting, and web processing. Common repair issues include air valve leaks, clutch slippage due to worn friction plates, solenoid valve failures, and improper air pressure regulation affecting engagement response.
Spring-Applied Brakes (SB Series)
Spring-engaged safety brakes for emergency stopping and load holding on motors and drive shafts. Repair demands typically involve spring weakening, friction lining wear, pilot pressure failures, and slow engagement response in high-cycle applications.
Multi-Disc Clutch Assemblies (MDC Series)
Heavy-duty multi-plate friction clutches for high-torque textile machinery, paper mills, and industrial dryers. Common faults include disc warping from thermal stress, oil degradation affecting friction characteristics, seal leakage, and progressive slippage under load.
Solenoid Valve Control Modules (SVM Series)
Pilot-operated solenoid valves regulating air pressure to clutches and brakes. Repair issues include coil burnout, valve spooling stiction, spool seal degradation, and failure to vent air under de-energize conditions.
Friction Material Assemblies (FMA Series)
Replacement friction linings, plates, and wear components for all Aronson clutches and brakes. Degradation occurs from heat, moisture ingress, contaminated oil, and high-cycle fatigue. Improper material specification leads to engagement chattering and torque variance.
Pneumatic Control Assemblies (PCA Series)
Integrated air filtration, regulation, and actuation modules for Aronson clutch/brake systems. Common faults include regulator diaphragm rupture, clogged air filters reducing pilot pressure, pilot valve stiction, and condensation water contamination in air lines.

Common ARONSON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ARONSON equipment arriving at our workshop.
- ✓Air-Engaged Clutch Slipping Under Load — Friction plate wear reduces surface area contact, causing progressive slippage and heat generation. Low pilot air pressure from regulator drift or blocked air filters also starves the engagement force. Contaminated friction surfaces accelerate wear in dusty mill environments.
- ✓Spring-Applied Brake Slow Engagement Response — Spring stiffness decreases over time due to stress relaxation or metal fatigue, particularly in high-cycle applications. Air bleed orifices become partially blocked by corrosion or particulate matter, slowing pilot air venting and delaying spring engagement.
- ✓Multi-Disc Clutch Chattering During Engagement — Disc face warping from thermal cycling or uneven friction lining wear creates micro-slip during torque ramp-up. Improper friction material specification or incompatible oil viscosity (too high or too low) destabilizes engagement torque. Worn thrust bearings introduce axial play affecting disc stack alignment.
- ✓Solenoid Valve Coil Burnout or No Energize Response — Coil insulation breakdown from continuous duty, contaminated cooling air, or voltage spikes from unprotected motor circuits. Spool stiction from varnish buildup or mineral deposits prevents valve actuation even when coil energizes. Failed diode in 24VDC circuits allows reverse voltage spikes to destroy coil windings.
- ✓Pneumatic Control Assembly Regulator Diaphragm Rupture — Diaphragm material embrittlement from age, excessive pilot pressure cycling, or contamination by water droplets in compressed air. Impact damage from installation or mishandling also perforates the diaphragm, causing uncontrolled pressure rise or loss.
- ✓Friction Plate Surface Degradation and Oil Contamination — Moisture ingress into gearbox or clutch housings from condensation or wash-down water reacts with friction material and base oil, forming acids and sludge. Lack of regular oil analysis misses early contamination signs. High operating temperatures above design limits accelerate friction lining breakdown.

Frequently Asked Questions — ARONSON Repairs
Do you repair Aronson clutches and brakes anywhere in India?+
Yes. Synchronics repairs the complete Aronson product range — air-engaged clutches, spring-applied brakes, multi-disc assemblies, solenoid valve controls, and friction material components. We offer door pickup service across India from our Vadodara, Gujarat facility, with pan-India presence in Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, and Ahmedabad. Turnaround time typically 7-10 business days.
What is the difference between Aronson air-engaged and spring-applied brakes?+
Air-engaged clutches use pneumatic pressure to create friction engagement for torque transmission — when air pressure is removed, a spring releases the friction surfaces. Spring-applied brakes are safety devices that default to engaged (holding) state by spring force alone; pneumatic pressure must be continuously supplied to release the brake. For emergency stopping or load holding, spring-applied brakes are the correct choice. Synchronics can diagnose which device your application requires and repair both types expertly.
My Aronson clutch is slipping and losing torque. What should I check first?+
First, verify the pilot air pressure at the solenoid inlet — it should match the nameplate specification (typically 5-6 bar). Low pressure indicates a blocked air filter, regulator drift, or leaking air lines. Second, inspect for visible wear or heat discoloration on friction plates. Third, check the oil condition for contamination or incorrect viscosity. If pressure and oil are normal but slippage persists, friction plate thickness is likely below tolerance. Contact Synchronics for a pressure test and friction surface inspection — we can typically restore full torque capacity through professional service.
Can Synchronics repair Aronson equipment on-site at my plant?+
For most repairs, we recommend sending the equipment to our Vadodara facility where we have full test benches, OEM spare parts inventory, and specialized diagnostic tools. However, for emergency pilot pressure troubleshooting, air line checks, and solenoid valve inspection, our field service engineers can visit major industrial clusters in Gujarat, Maharashtra, and Rajasthan. Contact us with your location and application details for on-site service feasibility.
Do you stock replacement Aronson friction plates and seals?+
Yes. Synchronics maintains in-stock inventory of common Aronson friction plate sets, spring packs, seals, and solenoid cartridges for AC Series, SB Series, and MDC Series clutches and brakes. For rare or discontinued models, we source OEM or equivalent materials within 3-5 days. All replacements are tested for dimensional accuracy and friction coefficient before installation. Custom friction lining material (asbestos-free, high-temperature, oil-resistant) can be specified for specialized applications.
How do I send my ARONSON 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 ARONSON 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 ARONSON 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 ARONSON 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.
