Struggling with Motor Bearing Reliability? The 6700 Series Delivers Consistent Performance
Finding the right deep groove ball bearings for motors can be challenging. Mismatched dimensions lead to installation delays, while low-quality bearings cause premature wear and unexpected downtime. Sourcing from multiple suppliers wastes time comparing specifications and lead times—especially when dealing with international brands like NSK and NTN.
Engineered for Motor Applications: The 6700, 6701, and 6702 Series
Our NSK NTN 6700 series deep groove ball bearings solve these problems with precise manufacturing and versatile options. Available in open, Zz shielded, and 2RS sealed configurations, they fit common motor shaft sizes (10mm, 12mm, 15mm bores) with interchangeable dimensions. Backed by ISO 9001-certified quality control, these bearings meet P0 to P4 precision standards, ensuring smooth operation in electric motors and automation equipment.
Optimal Performance in Motor Operating Conditions
These bearings excel in radial load applications with operating speeds suited for small to medium motors. The 0° contact angle maximizes radial load capacity, while vibration classes Z1V1 to Z3V3 allow selection based on noise sensitivity—critical for household appliances and precision machinery. Choose grease or oil lubrication to match your maintenance schedule and operating environment.
Key Engineering Features for Long Motor Life
Bearing steel construction provides the hardness needed to resist wear under continuous use, while precision ratings (P0-P4) control dimensional tolerance for proper fit. Sealed variants (2RS) protect against dust and moisture in industrial settings, reducing lubrication loss and extending service intervals. The unseparated design simplifies installation, ensuring consistent performance across motor assemblies.
Why Choosing the Right Bearing Lowers Total Cost
Investing in quality deep groove ball bearings reduces long-term costs. Inferior bearings with poor precision cause shaft misalignment, leading to motor overheating and premature failure. Our 6700 series meets strict vibration and load standards, minimizing equipment downtime and replacement frequency. With OEM/ODM capabilities, we can also tailor solutions to unique motor designs, avoiding the expense of custom modifications.
Quality You Can Rely On
All bearings undergo ISO 9001-certified production processes, including raw material inspection and成品尺寸、硬度及表面处理检测. We offer a warranty against manufacturing defects, ensuring peace of mind for your motor applications. With extensive inventory, we support low minimum order quantities and fast shipping via快递、空运或海运, meeting both small-scale repairs and large production runs.
