BIRCHER Product Lines We Repair
Our engineers are trained on the full BIRCHER product range. Below are the major product families we service.
Standard Slip Rings (SR Series)
Bircher standard slip rings for general industrial rotating machinery with 2-48 circuits. Common failures include brush wear causing signal dropout, contact resistance increase from oxidation, and bearing play leading to contact misalignment. Repair involves brush replacement, contact cleaning, and bearing re-tensioning.
High-Speed Slip Rings (HS Series)
Bircher high-speed slip rings rated for 1500-3000 RPM applications in spindles and precision rotating equipment. Failure modes include brush arcing at elevated speeds, cage wear in ball bearings, and thermal degradation of contact materials. Synchronics restores these with precision balancing and premium contact material upgrades.
Rotary Joints - Hydraulic (RJ-H Series)
Bircher rotary hydraulic joints for high-pressure fluid transfer in rotating shafts. Common issues are seal degradation causing leakage, internal cavity scoring, and ball bearing corrosion from hydraulic fluid contamination. Full seal and bearing replacement restores operational life.
Rotary Joints - Pneumatic (RJ-P Series)
Bircher pneumatic rotary joints for air supply in rotating machinery, textile spindles, and rotary dryers. Failures stem from seal brittleness in high-temperature environments, valve cartridge sticking, and bearing rust from moisture ingress. Synchronics supplies sealed cartridge assemblies and stainless hardware.
Combination Slip Ring & Rotary Joints (CR Series)
Bircher integrated units combining electrical slip rings with fluid rotary joints in single housing for space-constrained applications. Repair complexity involves separating mechanical and electrical sections, addressing cross-contamination issues, and reassembling with proper seal sequencing.
Fibre Optic Rotary Couplers (FO Series)
Bircher fibre optic signal transmission units for EMI-free high-speed data in rotating machinery. Failures include fibre misalignment causing signal loss, ferrule contamination, and bearing wear affecting optical coupling. Repair requires precision fibre alignment tools and optical power verification.

Common BIRCHER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BIRCHER equipment arriving at our workshop.
- ✓Brush wear and electrical contact dropout — Bircher slip ring brushes degrade from friction, oxidation, and arcing over 2000-5000 operating hours depending on load and speed. This causes intermittent signal loss, noise in analogue circuits, and eventual open circuits in digital transmission channels.
- ✓Signal dropout at varying shaft angles — Bearing play in Bircher slip rings causes brush wobble and intermittent contact loss, especially noticeable when rotating machinery changes load or speed. This is common in older HS-series units operating beyond rated life or subjected to radial loads.
- ✓Hydraulic fluid leakage from rotary joint seals — Bircher RJ-H rotary joints experience seal lip wear and hardening after 5-10 years, especially in high-temperature or contaminated hydraulic environments common in Indian textile mills and steel processing. Microbial growth in stagnant fluid accelerates degradation.
- ✓Pneumatic rotary joint frozen cartridge valve — Bircher RJ-P pneumatic joints suffer from moisture and dust ingress in humid Indian plant environments, causing internal valve corrosion and sticky cartridge movement. This blocks air flow and creates unsafe pressure conditions.
- ✓Fibre optic signal loss and coupling misalignment — Bircher FO-series couplers lose optical power due to ferrule end-face contamination, dust ingress, or bearing wear causing axial and radial misalignment of the fibre cores. This manifests as intermittent data transmission errors or complete signal blackout.
- ✓Combined electrical and hydraulic failure in CR-series units — Bircher CR combination units fail when seal degradation allows hydraulic fluid to migrate into electrical slip ring cavities, corroding brush holders and contact rings. This creates both leakage and electrical shorts simultaneously.

Frequently Asked Questions — BIRCHER Repairs
Do you repair Bircher slip rings and rotary joints anywhere in India?+
Yes. Synchronics has authorised repair capability for the complete Bircher product portfolio across all of India. We offer door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, Kolkata, and all industrial centres. Your equipment is serviced at our ISO 9001 certified facility in Vadodara, Gujarat, and returned with a comprehensive test report and warranty.
What is the typical repair turnaround for a Bircher slip ring?+
Standard slip ring repairs (brush replacement, contact cleaning) take 5-7 working days. High-speed or combination units (CR-series) requiring seal replacement and dual-section testing take 10-14 days. We provide daily update calls for critical machinery. Emergency expedite service is available on request with additional charges.
Can you repair Bircher rotary joints that are leaking hydraulic fluid?+
Yes, absolutely. Hydraulic rotary joint seal failure is one of our most common Bircher repairs. We disassemble the joint, inspect internal surfaces for scoring or corrosion, replace all elastomer seals and O-rings with Bircher-approved materials, and pressure-test to 150% rated working pressure. We also provide fluid compatibility recommendations for your specific operating environment.
Do you stock Bircher replacement parts, or is everything built to order?+
We maintain inventory of common wear items including brush assemblies, seal kits, bearing sets, and O-ring compounds for standard Bircher series. Specialised items like fibre optic ferrules or custom cartridge valves are sourced through our Bircher network. Lead time for stocked parts is same-day; custom items are typically 5-10 days from Switzerland.
How do I know if my Bircher slip ring is failing or just needs cleaning?+
Early signs include intermittent signal noise, resistance reading above 50 milliohms, or visible brush dust. Synchronics performs free remote diagnostics: send a photo of the unit and its fault symptoms, and we advise whether cleaning or replacement is needed. Most Indian textile mills can prevent failure through annual preventive maintenance rather than emergency repair.
How do I send my BIRCHER 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 BIRCHER 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 BIRCHER 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 BIRCHER 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.
