FAG Product Lines We Repair
Our engineers are trained on the full FAG product range. Below are the major product families we service.
FAG Deep Groove Ball Bearings (6000/6200 Series)
Standard deep groove ball bearings used in motors, fans, and pumps. Common issues include raceway spalling, cage wear, seal failure, and bearing noise due to contamination or inadequate lubrication in dusty Indian manufacturing environments.
FAG Spherical Roller Bearings (22000 Series)
Heavy-duty bearings for misalignment tolerance in crushers, mills, and vibrating machinery. Failure modes include inner ring cracking, roller skidding, and overheating in high-load Indian quarrying and mineral processing operations.
FAG INA Linear Guides and Blocks
Precision linear motion systems for CNC machines, textile looms, and packaging equipment. Typical faults include rail corrosion, block jamming, preload loss, and carriage binding from thermal expansion or contaminant ingress in Indian humid climates.
FAG Angular Contact Bearings (7000 Series)
High-speed precision bearings for spindles, compressors, and turbomachinery. Repair challenges include ceramic hybrid bearing damage, preload spring corrosion, and thermal growth in Indian textile and machine tool facilities.
FAG Pillow Block Units (SNH/SNV Series)
Integrated bearing housings with sensors and seals for automated condition monitoring in pumps and conveyor systems. Common failures include sensor malfunction, bearing-to-shaft fretting, and housing corrosion in wet sugar mill and dairy environments.
FAG Tapered Roller Bearings (30000 Series)
Load-carrying bearings for vehicle hubs, gear reducers, and spindles in Indian automotive and machinery sectors. Repair issues include cone/cup separation, bearing end play deviation, and retainer fracture from shock loads.

Common FAG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FAG equipment arriving at our workshop.
- ✓Raceway spalling and flaking on bearing rings — Causes include cyclic loading beyond bearing dynamic load rating, contamination ingress (sand, moisture) from open environments typical in Indian foundries and textile mills, inadequate or degraded lubrication, and misalignment. Spalling initiates as micro-cracks under subsurface stress and propagates outward.
- ✓Bearing cage wear and ball/roller skidding — Cage damage results from inadequate lubrication, contamination-induced friction, thermal expansion mismatches, or excessive vibration common in unbalanced Indian machinery. Skidding causes secondary raceway damage, heat generation, and bearing seizure. Phenolic cages degrade faster in dusty or humid mill environments.
- ✓FAG linear guide block jamming and carriage stiction — Jamming occurs from thermal expansion, corrosion of steel rails and balls in humid coastal or monsoon-prone Indian facilities, contamination (salt, coolant residue, lint), inadequate preload adjustment, or misalignment during installation on CNC machines and textile looms.
- ✓Bearing preload loss and axial play increase — Preload springs relax over time, stainless steel shim shims corrode and reduce thickness in humid Indian environments, bearing ring wear accommodates increased radial clearance, or mounting bolts loosen due to vibration. Angular contact and tapered roller bearings become noisy and prone to skidding when preload drops below specification.
- ✓FAG pillow block sensor malfunction and electrical noise — Integrated sensors in FAG SNH/SNV bearing units experience connection corrosion, moisture intrusion in cable glands, connector pin oxidation, or sensor winding insulation breakdown from vibration-induced stress. Electrical noise couples into control signals in Indian sugar mill and dairy automation systems.
- ✓Deep groove ball bearing noise and vibration surge — Noise originates from cage slip/skidding, contamination scratching raceway surfaces, inadequate lubrication starvation, internal clearance increase from wear, or micro-vibrations transmitted through loosely mounted bearings in Indian machinery. Surge indicates imminent seizure.

Frequently Asked Questions — FAG Repairs
Do you repair FAG bearings and bearing units anywhere in India?+
Yes. Synchronics offers nationwide FAG bearing repair and reconditioning services. We handle deep groove ball bearings (6000 series), spherical roller bearings (22000 series), angular contact bearings (7000 series), tapered roller bearings (30000 series), FAG INA linear guides, and integrated pillow block units (SNH/SNV). Our Vadodara facility includes precision balancing, alignment equipment, and bearing testing rigs. We offer door-to-door pickup and express turnaround from all major Indian cities including Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Kolkata, and Ahmedabad.
What is the typical turnaround time for FAG bearing repair at Synchronics?+
Standard FAG bearing repair typically takes 5-7 working days depending on damage severity and spare parts availability. Deep groove ball bearing replacement and preload correction: 3-4 days. Linear guide restoration and recalibration: 5-6 days. Pillow block bearing unit replacement with sensor integration test: 6-7 days. We offer expedited service (2-3 days) for critical production machinery. Parts are sourced from FAG authorized distributors in India to ensure OEM compliance and warranty. Emergency courier service available for time-sensitive repairs in Indian manufacturing plants.
Can Synchronics repair FAG bearings with sensor integration like SNH and SNV pillow blocks?+
Yes, fully. Synchronics is experienced in FAG SNH and SNV integrated bearing units with built-in temperature and vibration sensors. We perform complete electrical testing of sensor circuits, cable harness inspection, and connector rehabilitation. If sensor electronics are faulty, we replace the entire bearing unit with factory-equivalent FAG components. Sensor calibration and signal output verification is performed using precision test equipment. This expertise is critical for Indian sugar mills, dairies, and automated packaging lines relying on condition-based maintenance.
What is the difference between FAG C3 and C4 bearing clearance, and when does Synchronics recommend each?+
FAG C3 (wider internal clearance) and C4 (even wider clearance) classes are selected based on operating speed, thermal growth, and preload strategy. Synchronics recommends C3 for standard industrial motors and fans in Indian textile and food plants operating at moderate speeds. C4 is specified for high-speed spindles, compressors, and turbines where thermal expansion is significant, or for bearings with external preload springs. During FAG bearing replacement, we select the correct clearance class based on OEM specifications and measured operating conditions. Incorrect clearance selection causes premature wear and noise; Synchronics provides guidance during diagnosis.
Does Synchronics offer FAG linear guide (INA) restoration and re-certification?+
Yes. FAG INA linear guides used in CNC machines, textile looms, and packaging equipment are cleaned, inspected, tested, and recertified by Synchronics. We perform ultrasonic cleaning, borescope inspection of rails and blocks, preload measurement and adjustment, and full travel testing on precision test benches. Corroded or damaged blocks are replaced with OEM FAG INA equivalents. Rail straightness is verified using laser alignment; geometric accuracy is confirmed per DIN/ISO standards. Reconditioned FAG INA guides are ideal for cost-conscious Indian manufacturers seeking to extend CNC machine tool life without replacement.
How do I send my FAG 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 FAG 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 FAG 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 FAG 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.
