Minimize Downtime with Reliable Deep Groove Ball Bearing 6704-2RS
Equipment failures caused by substandard bearings cost manufacturers thousands in lost production daily. Many buyers struggle with inconsistent quality from unknown suppliers, while others face rigid minimum order quantities that delay urgent repairs. The 20x27x4mm 6704-2RS bearing is critical for small to medium industrial machinery—compromising on precision here leads to premature wear, increased noise, and unexpected shutdowns.
Precision Engineered for Industrial Machinery Performance
Our Deep Groove Ball Bearing 6704-2RS addresses these challenges with strict manufacturing standards and flexible supply. Produced in our ISO 9001:2015 certified facility, each bearing meets P0-P4 precision grades and Z1V1-Z3V3 vibration levels, ensuring smooth operation in motors, pumps, and conveyor systems. With 15+ years of export experience to Europe and North America, we understand the critical role consistent bearing performance plays in your production line.
Optimized for High-Speed, Low-Maintenance Applications
This 20x27x4mm Deep Groove Ball Bearing excels in radial load environments with operating speeds up to industry standards for its size class. The double rubber seal (2RS) design provides effective protection against dust and moisture, extending service life in both clean workshops and semi-harsh industrial settings. Its single-row, non-aligning structure delivers reliable performance in applications where shaft misalignment is minimal, making it ideal for precision machinery components.
Technical Features That Maximize Equipment Uptime
The 6704-2RS bearing’s performance is defined by critical engineering details: Precision ratings from P0 (standard) to P4 (high precision) control dimensional accuracy, directly impacting rotational stability in high-speed applications. Vibration grades Z1V1 to Z3V3 reduce noise and energy loss, a key consideration for quiet operation in consumer goods manufacturing. Constructed from high-grade bearing steel, it balances hardness and toughness to withstand continuous radial loads without premature fatigue. The 0° contact angle optimizes radial load distribution, while the unseparated design simplifies installation and maintenance.
Why Genuine Bearings Reduce Total Cost of Ownership
Counterfeit bearings often fail within months, requiring emergency replacements and unplanned downtime. A single production line shutdown can cost more than 10x the price of a genuine bearing. Our 6704-2RS bearings undergo comprehensive testing—including dimensional inspection and vibration analysis—to meet ISO, ABMA, and DIN standards. By choosing authentic bearings, you avoid hidden costs: no repeat purchases, no production losses, and no secondary damage to connected machinery. Our 12-month warranty further protects your investment, covering manufacturing defects with either replacement or refund.
