Industrial operations face constant challenges from unexpected equipment failures—especially when critical components like bearings underperform. Many manufacturers struggle with bearings that fail prematurely due to poor material quality or imprecise manufacturing, leading to costly production halts and maintenance delays. Sourcing standard bearings with flexible order terms and consistent quality can also be a hurdle, particularly for businesses needing small quantities or urgent replacements.
Our 4204 and 4304 Deep Groove Ball Bearings address these pain points by combining high-grade bearing steel construction with strict manufacturing standards. Designed for industrial machinery, these bearings deliver reliable radial load support in applications like gearboxes, conveyors, and electric motors. With a dimension of 45x68x12mm, they fit seamlessly into standard equipment setups, ensuring easy replacement and minimal downtime. Backed by our 17 years of manufacturing experience, we offer 1 piece MOQ for standard bearings, making small-batch orders or emergency repairs feasible without compromising on quality.
These deep groove ball bearings excel in moderate to high-speed industrial applications, where consistent rotation and load capacity are essential. The single-row, unseparated design provides stable operation under radial loads, making them ideal for machinery subject to continuous motion, such as CNC machine spindles and agricultural equipment conveyors. Their bearing steel material ensures durability, withstanding regular wear and tear in both indoor industrial settings and outdoor agricultural environments. Properly installed, these bearings maintain performance across a range of operating temperatures, supporting uninterrupted production schedules.
The 4204 and 4304 bearings are engineered with critical features that directly impact equipment performance. The bearing steel material offers high hardness and wear resistance, extending service life compared to lower-grade alternatives. The 45mm bore diameter and 68mm outer diameter provide a balanced size-to-load ratio, suitable for medium-duty industrial machinery. The 12mm width ensures sufficient contact area for load distribution, reducing stress on individual components. Additionally, the unseparated design simplifies installation and maintenance, minimizing the risk of assembly errors that can cause premature failure. These technical attributes collectively contribute to stable operation and reduced maintenance costs over time.
Choosing genuine bearings over counterfeit alternatives directly affects your bottom line. Counterfeit bearings often use substandard materials and lack precision manufacturing, leading to early failure, increased energy consumption, and potential damage to connected equipment. A single bearing failure can result in hours of production downtime, costing far more than the initial savings from cheap alternatives. Our bearings meet ISO international standards, ensuring consistent quality and performance. With a 12-month warranty, we stand behind every product, offering free replacement for qualified defects—protecting your investment and reducing long-term operational risks.
