HUBNER Product Lines We Repair
Our engineers are trained on the full HUBNER product range. Below are the major product families we service.
Hubner Coupling Systems
Flexible and rigid couplings designed for torque transmission and vibration damping. Common issues include elastomer degradation, misalignment-induced wear, and hub bore cracking under shock loads. Synchronics restores coupling balance, replaces elastomer elements, and realigns shafts.
Hubner Encoder Systems
Absolute multiturn and incremental encoders for position feedback in automation. Typical faults include signal loss, bearing wear causing optical misalignment, and connector corrosion in damp manufacturing environments. Synchronics recalibrates optical paths and replaces worn bearings and seals.
Hubner Rotary Unions & Slip Rings
Rotary unions for fluid and gas transfer, slip rings for electrical signal routing in rotating equipment. Leakage, signal dropout, and seal erosion are common. Synchronics replaces seal packages, cleans collector rings, and restores electrical contact integrity.
Hubner Shaft Encoders & Monitors
Shaft-mounted encoders with integrated monitoring for bearing health and vibration detection. Failures include LED degradation, photo-sensor contamination, and bearing preload loss. Synchronics cleans optical components, recalibrates sensor thresholds, and replaces bearing cartridges.
Hubner Torque Limiters & Safety Couplings
Slip clutches and torque-limiting couplings protecting machinery from overload and shock. Wear of friction discs, spring relaxation, and slip calibration drift are typical failures. Synchronics recalibrates slip thresholds, replaces friction materials, and restores safety certification.

Common HUBNER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HUBNER equipment arriving at our workshop.
- ✓Encoder signal loss or intermittent output — Hubner encoders in textile mills and paper plants experience signal dropout due to optical path contamination from dust and moisture, or misalignment caused by bearing wear. Connector corrosion in humid environments also disrupts signal transmission.
- ✓Coupling elastomer hardening and loss of damping — Hubner flexible couplings in high-temperature Indian foundries and forges experience elastomer material degradation from thermal cycling and oil contamination. This causes vibration transmission and potential shaft misalignment leading to bearing damage.
- ✓Rotary union fluid leakage at bearing housing interface — Hubner rotary unions in paper machines and textile spindle systems develop leakage when seal packages wear under continuous rotation and pressure cycling. High mineral content in water supplies accelerates seal erosion.
- ✓Slip ring contact wear causing signal noise and data corruption — Hubner slip rings in continuous-duty applications like rotary kilns and centrifuges wear brush-to-ring contacts from repetitive mechanical wiping and electrical arcing. Carbon brush depletion and collector ring corrosion accelerate degradation.
- ✓Torque limiter slip calibration drift or friction disc wear — Hubner safety couplings in punch press and heavy die applications lose torque setpoint accuracy over time due to friction material wear, spring relaxation, and thermal cycling. Exceeding setpoint causes uncontrolled slip and machine damage.
- ✓Bearing preload loss in encoder shaft assemblies — High-speed Hubner encoders in automotive assembly line feedback systems experience bearing preload loss from bearing cartridge settlement and lubricant breakdown. This increases radial runout, misaligning the optical disk and causing measurement errors.

Frequently Asked Questions — HUBNER Repairs
Do you repair Hubner equipment anywhere in India?+
Yes. Synchronics repairs the complete Hubner product range — couplings, encoders, rotary unions, slip rings, and torque limiters. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all industrial centers. Equipment is serviced at our Vadodara, Gujarat facility and returned with test certificates.
Can Synchronics repair Hubner encoders with absolute multiturn capability?+
Absolutely. Hubner HOG 4020, HOG 4040, and multiturn absolute encoders are regularly serviced at Synchronics. We diagnose multiturn data corruption, recalibrate optical sensors, replace worn bearings, and restore full position tracking accuracy. Post-repair testing confirms absolute accuracy and battery-backed data integrity.
What is the typical turnaround time for Hubner coupling repair?+
Standard Hubner flexible coupling repairs — elastomer replacement, bore cleaning, dynamic balancing — take 5-7 working days. Critical couplings can be expedited to 48 hours. Synchronics maintains stock of common elastomer inserts and replacement parts to minimize downtime in Indian manufacturing plants.
How do you handle Hubner rotary union seal replacement and pressure testing?+
Synchronics completely disassembles Hubner rotary unions, inspects bearing races and shaft seals, replaces all seal packages with OEM-equivalent parts, and pressure-tests to 1.5x rated pressure. We document seal replacement date, part numbers, and test results for maintenance records and regulatory compliance.
Do you repair Hubner torque limiters and recalibrate slip setpoints?+
Yes. We recalibrate Hubner slip clutches and torque-limiting couplings using calibrated torque measurement equipment. Typical service includes friction disc replacement, spring preload adjustment, and verification testing. Synchronics issues a calibration certificate showing actual slip torque against specification for safety-critical applications.
How do I send my HUBNER 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 HUBNER 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 HUBNER 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 HUBNER 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.
