BOSCH REXROTH Equipment We Repair — By Category
BOSCH REXROTH Product Lines We Repair
Our engineers are trained on the full BOSCH REXROTH product range. Below are the major product families we service.
IndraDrive Servo Drive Systems
Compact AC servo drives delivering high-speed, high-torque control for motion applications. Common faults include encoder communication failures, gate driver failures on power modules, and firmware corruption after voltage spikes or phase loss events.
A4VSO Axial Piston Pump
Variable displacement, swashplate hydraulic pumps controlling flow and pressure in injection molding, presses, and marine winch systems. Wear patterns in spool grooves, pilot control cartridge leakage, and swashplate bearing degradation are primary failure modes.
PSV Proportional Directional Control Valves
Closed-center, proportional spool valves for load-sensing hydraulic systems in steel rolling mills and plastic extrusion lines. Solenoid coil burnout, spool stiction, and internal leakage reduction are routine repair requirements.
IndraControl Motion Control Platforms
Real-time control systems for multi-axis coordination in textile machinery and automotive assembly. CPU board failures, Ethernet port degradation, and SD card corruption affect system availability in harsh plant environments.
Bosch Rexroth Hydraulic Cylinders
High-pressure welded and tie-rod cylinders for stamping, forging, and clamping circuits. Piston rod corrosion, seal kit wear accelerated by mineral oil degradation, and bearing sleeve scoring require specialized rod rework and honing services.
ABAPROP Proportional Solenoid Valves
Pilot-operated proportional directional spool valves for textile sizing, coating, and cooling circuits requiring fast response and tight flow control. Spool stiction from varnish deposits and solenoid armature corrosion are frequent issues in humid climates.

Common BOSCH REXROTH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BOSCH REXROTH equipment arriving at our workshop.
- ✓IndraDrive servo encoder communication loss — Bosch Rexroth IndraDrive systems rely on absolute encoders (EnDat or BiSS feedback). Corroded M23 connector pins, damaged shielded cable jackets, or failed encoder supply circuits cause CRC checksum failures and axis shutdown. Common in humid coastal plants and washdown environments.
- ✓A4VSO pump pressure relief valve leakage — Bosch Rexroth A4VSO variable displacement pumps use cartridge-type pressure relief elements. Mineral oil varnish deposits, abrasive particle ingestion (from worn filter elements), or poppet seat erosion cause internal bypass leakage. System pressure drops below setpoint, reducing clamping force or flow to actuators.
- ✓PSV proportional spool stiction and null deviation — Rexroth PSV proportional directional valves experience spool stiction when mineral oil oxidation products, corrosion particles from steel spools, or incompatible paint residues accumulate in the 0.05mm spool-bore clearance. Solenoid command signal produces asymmetric spool response, causing load drift.
- ✓IndraControl L30/L35 CPU board capacitor failure — Bosch Rexroth industrial control boards operate in 40-45C ambient temperatures in Indian textile mills and steel plants. Electrolytic capacitors rated 85C degrade rapidly; localized heating from IGBTs accelerates cathode material dissolution, causing bulging or opening of capacitor terminals after 5-7 years.
- ✓Bosch Rexroth cylinder piston rod corrosion and scoring — Hydraulic cylinders in sugar mills and fertilizer plants experience piston rod corrosion when mineral oil moisture content exceeds 500ppm or water droplets condense on rods during idle periods. Corrosion pitting initiates fatigue cracks; scoring from particulate generates leakage past seals.
- ✓ABAPROP solenoid coil burnout and armature corrosion — Bosch Rexroth proportional solenoid valves in wet environments (textile dyeing, coating lines, washdown areas) suffer moisture ingress through cable glands. Coil insulation resistance drops, causing phase leakage to ground or coil burnout. Armature surfaces oxidize, increasing air-gap reluctance and reducing solenoid force.

Frequently Asked Questions — BOSCH REXROTH Repairs
Do you repair Bosch Rexroth equipment anywhere in India?+
Yes. Synchronics repairs the full Bosch Rexroth product range - IndraDrive servo drives, A4VSO hydraulic pumps, PSV proportional valves, IndraControl motion controllers, and custom hydraulic cylinders. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Kolkata, and all other industrial cities. All equipment is serviced in our central facility in Vadodara, Gujarat, and returned within 7-14 days.
What is your repair turnaround time for Bosch Rexroth IndraDrive servo drives?+
Most IndraDrive repairs complete within 2-5 working days. If the drive has encoder communication faults or power module failures, we diagnose the root cause using test loads and signal analysis on day 1, source components on day 2, perform repair and bench testing on days 3-4, and ship on day 5. Emergency express repairs are available for critical production lines - call +91-265-2422222 to arrange.
How do I know if my A4VSO pump needs internal repair versus just seal replacement?+
Bosch Rexroth A4VSO pumps showing low system pressure at full displacement, audible cavitation noise, or oil overheating typically need internal cartridge and poppet seat work, not just seals. Synchronics performs a free pressure test and flow test at our facility to confirm the condition. We send you a detailed diagnostic report with repair cost before starting work, so you know exactly what's needed.
Do you stock genuine Bosch Rexroth spare parts or do you use compatible alternatives?+
Synchronics uses OEM-equivalent industrial-grade components certified to Bosch Rexroth specifications (e.g., FKM seals, polyimide solenoid wire, chrome-plated rods). We do not use counterfeit parts. For critical applications, we can source genuine Bosch Rexroth spare parts from distributors, though lead times may extend repair time by 3-5 days. All rebuilt equipment includes a 12-month parts warranty.
Can you repair Bosch Rexroth proportional directional control valves if they have internal varnish buildup?+
Yes. Bosch Rexroth PSV and ABAPROP valves experiencing spool stiction from oxidized mineral oil are completely disassembled and ultrasonically flushed at Synchronics. The spool bore is precision-honed to restore the 0.05mm clearance, seals are replaced, and response time is verified through dynamic flow bench testing. This service typically costs 35-50% less than purchasing a new valve and saves replacement lead time.
How do I send my BOSCH REXROTH 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 BOSCH REXROTH 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 BOSCH REXROTH 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 BOSCH REXROTH 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.
