OBARA Equipment We Repair — By Category
OBARA Product Lines We Repair
Our engineers are trained on the full OBARA product range. Below are the major product families we service.
OBL Series Spindle Motors
High-speed precision spindle motors (5,000-40,000 RPM) for CNC machining centres. Common faults include bearing preload loss, winding insulation breakdown, and spindle runout exceeding tolerance, causing tool chatter and dimensional errors on finished parts.
Rotary Union / Through-Spindle Coolant Systems
High-pressure rotary unions for coolant delivery in spindle bores. Failures include seal degradation, internal passage blockages, and bearing wear, leading to coolant leakage and reduced machining surface quality.
Spindle Taper Lock & ATC Interfaces
Mechanical coupling systems for automated tool changer integration. Issues include wear in taper interfaces, loss of clamping force, and tool slip during high-load roughing operations, compromising part accuracy.
Spindle Bearing Cartridge Assemblies
Pre-loaded angular contact bearing sets for OBARA spindles. Typical faults: bearing cage fracture, preload collapse, and inner race spalling causing excessive axial/radial play and catastrophic spindle failure.
Spindle Drive Servo Amplifiers
Dedicated servo drives for OBARA motor speed and torque control. Common failures include capacitor dry-out, gate driver faults, and encoder signal loss, resulting in spindle speed instability and parameter errors.

Common OBARA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in OBARA equipment arriving at our workshop.
- ✓Spindle bearing preload loss and increased runout — Angular contact bearings in OBL motors lose preload tension due to thermal cycling, worn bearing spacers, or metal-to-metal contact degradation. This causes axial and radial movement exceeding 0.05mm, visible as tool chatter marks on machined surfaces.
- ✓Winding insulation failure and phase-to-ground short — Stator winding insulation in OBARA spindle motors degrades due to thermal stress, coolant ingress, or age-related varnish cracking. High-speed vibration and thermal cycling accelerate insulation breakdown, causing arcing between windings or frame ground.
- ✓Rotary union seal leakage and coolant contamination — High-pressure rotary union seals in through-spindle coolant systems wear from abrasive coolant particles, thermal cycling, or excessive bearing radial play. Loss of sealing causes oil/coolant spray into spindle bearing cavity, degrading lubricant cleanliness.
- ✓Servo amplifier capacitor failure and power-on fault — Aluminum electrolytic capacitors in OBARA spindle drive amplifiers (SPA series) dry out due to high ambient factory temperatures (40-50°C) and continuous operation. Failed capacitors cause DC bus voltage ripple, triggering overvoltage shutdown and repeated power cycling.
- ✓Encoder signal loss and spindle speed feedback failure — Rotary encoders coupled to OBARA spindle motors fail due to connector corrosion, cable damage from coolant spray, or encoder bearing wear. Signal loss causes drive to enter limp-home mode, limiting RPM to ~1000 and triggering fault codes.
- ✓Taper lock ATC coupling slippage under load — Wear in the IS30 or ISO40 taper interface, loss of clamping pressure in pull-stud mechanism, or tool shank damage reduces grip force. During heavy roughing cuts (>5 kW), the tool rotates relative to spindle nose, causing severe chatter and part scrap.

Frequently Asked Questions — OBARA Repairs
Do you repair OBARA spindle motors anywhere in India?+
Yes. Synchronics repairs the full OBARA spindle product range — OBL motors, rotary unions, bearing cartridges, ATC couplings, and servo amplifiers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other cities. Same facility in Vadodara, Gujarat. Most OBARA spindle repairs completed in 7-10 working days.
What is the typical cost and turnaround for OBARA spindle motor rewind?+
Full stator rewind of OBL series motors (OBL-500 to OBL-5000) costs INR 8,000-18,000 depending on winding complexity and material grade. Turnaround is 5-7 working days including insulation testing, rotor dynamic balancing, and runout verification. Synchronics provides 12-month warranty on all rewound motors.
Can you repair OBARA spindle bearing cartridges without replacing the entire spindle?+
Yes. If only bearings are worn or preload is lost, Synchronics disassembles the cartridge, removes worn bearings, inspects races for spalling, and installs new angular contact sets with factory-spec preload shims. This costs 40-50% less than full spindle replacement. Cartridges returned with bearing runout <0.02mm and axial play <0.01mm.
What causes OBARA through-spindle coolant system leakage?+
Rotary union seals degrade from abrasive coolant particles, thermal shock, or bearing wear in the spindle cartridge itself. When preload is lost, radial play increases, stressing the union seal. Synchronics inspects both the spindle bearings and rotary union seals together, replacing worn components and flushing all internal passages to prevent future contamination.
Do you stock OBARA spindle motor spare parts?+
Synchronics maintains stock of common OBARA replacement parts including angular contact bearings (BC series), preload shim kits, seal kits for rotary unions, and encoder assemblies. For OBL motor stators and rotors, we source directly from OBARA Japan or authorized suppliers within 3-5 days. We provide genuine and equivalent OEM-spec alternatives.
How do I send my OBARA 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 OBARA 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 OBARA 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 OBARA 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.
