Ask a custom question
Q.01 How can I verify the authenticity of NTN bearings I receive?

Every NTN bearing has laser-engraved batch codes on the inner ring. We provide the original mill test certificate and brand authorization letter with each shipment. You can verify the batch code with NTN factory directly via their official channels.

Q.02 What is the typical lead time and minimum order quantity?

In-stock items ship within 5-7 working days. MOQ starts from 1 piece for samples. Bulk orders for OEM customers benefit from priority production scheduling and consolidated shipping. Custom non-standard bearings typically take 30-45 days.

Q.03 Do you offer OEM customization (clearance, sealing, precision)?

Yes. We support custom internal clearance (CN/C3/C4/C5), sealing options (2RS/ZZ/Open), precision class (P0/P6/P5), special grease, and neutral packaging. Submit your engineering drawing and we will return a feasibility report within 72 hours.

Q.04 What documentation is provided for international shipping?

Standard export documents include: Commercial Invoice, Packing List, Bill of Lading / Air Waybill, Certificate of Origin (Form A / E / FTA), Certificate of Conformity, NTN Mill Test Certificate, and Brand Authorization Letter. Customs HS code and country-specific requirements are pre-checked.

Q.05 What is your warranty and return policy?

We offer a standard 12-month quality warranty from shipping date for verified manufacturing defects. Defective products are replaced free of charge. Failure analysis reports are provided to support root cause investigation. Wear due to misapplication or improper installation is excluded.

Stop Precision Machinery Downtime with 527/940 Double Row Thrust Ball Bearing

Equipment managers in precision manufacturing know the cost of unexpected bearing failure—hours of production loss, missed deadlines, and expensive repairs. Many face counterfeit bearings with false certifications that fail prematurely, or multi-tier suppliers who can’t guarantee batch consistency for critical applications. When your CNC spindle or rotary table relies on precise axial load handling, compromised components risk more than downtime—they risk product quality.

Large Diameter Thrust Ball Bearing 527/940: In Stock and Traceable

Our 527/940 Double Row Thrust Ball Bearing addresses these challenges directly. As an official NTN distributor with ISO 9001 compliant quality systems, we ensure every bearing meets OEM-grade specifications with full traceability documentation. With WMS real-time inventory, this precision machinery bearing is available for immediate dispatch, eliminating the 30–50% lead time delays common in traditional distribution channels. Designed for axial load applications in high-precision equipment, it delivers the stability your production line demands.

Engineered for High-Axial Load Precision Applications

This Large Diameter Thrust Ball Bearing excels in scenarios where precise axial load management is critical. With a 0° contact angle and separated design, it efficiently handles pure thrust loads up to its rated capacity, making it ideal for precision machinery like CNC rotary tables and gearbox thrust stages. The non-aligning construction ensures rigidity in fixed-axis applications, while its bearing steel material provides durability in continuous operation environments—key for maintaining tight tolerances in manufacturing processes.

Technical Details That Drive Performance

The 527/940 Double Row Thrust Bearing’s performance is defined by critical specifications. Its precision ratings (P0 to P2) allow selection based on application requirements—P5 or P4 grades for high-speed spindles where runout must be minimized, and P0 for general industrial use. Vibration classes Z1V1 to Z3V3 ensure quiet operation, critical in noise-sensitive precision environments. The separated design simplifies installation and maintenance, reducing downtime during replacements. With lubrication flexibility (grease or oil), it adapts to both high-temperature and high-speed conditions, extending service life in diverse operating scenarios.

Why Genuine Bearings Lower Total Cost of Ownership

Choosing an ISO9001 Certified Thrust Bearing like the 527/940 avoids the hidden costs of counterfeit alternatives. Gray-market bearings often lack proper material heat treatment, leading to 30–50% shorter service life and unexpected failures. Our full traceability documentation prevents customs clearance delays and liability disputes, while consistent batch quality eliminates production variations. Over time, the reliability of genuine components reduces maintenance frequency and unplanned downtime, delivering lower total cost of ownership compared to cheaper, non-certified options.
