Need a 6328 Deep Groove Ball Bearing That Fits Your Motorcycle Parts?
Finding the right bearing for motorcycle components can be tricky. Mismatched dimensions lead to installation delays, while low-quality bearings often fail early with excessive noise or vibration. Sourcing from multiple suppliers for different brands only adds to the hassle.
Engineered for Consistent Performance in Motorcycle Applications
This NACHI 6328 deep groove ball bearing addresses these challenges with precise manufacturing and versatile design. As a professional bearing supplier with access to full product lines—including deep groove ball bearings like this model—we ensure you get the right part without unnecessary delays. Its 140x300x62 mm dimensions and radial load capacity make it suitable for motorcycle drivetrain and wheel applications where reliability is critical.
Optimal Performance in Radial Load Scenarios
Designed as a single-row radial bearing with a 0° contact angle, this 6328 model excels in applications with primarily radial loads, such as motorcycle wheel hubs and transmission components. The non-aligning design requires proper mounting alignment, but its unseparated structure ensures stable operation under consistent load conditions. Choose between Zz, 2RS, or open seals based on your protection and lubrication needs.
Key Specifications That Impact Longevity
The bearing steel construction provides the hardness needed to resist wear, while precision ratings from P0 to P4 allow selection based on application accuracy requirements. Vibration classes Z1V1 to Z3V3 let you match bearing smoothness to noise-sensitive environments—critical for motorcycle engines where excessive vibration affects rider comfort. Lubrication flexibility (grease or oil) allows adaptation to different operating temperatures and maintenance schedules, ensuring optimal performance throughout the bearing’s service life.
Why Choosing the Right 6328 Bearing Lowers Total Costs
Selecting a bearing that meets your motorcycle part’s exact specifications reduces the risk of premature failure. A precision P5-rated bearing, for example, minimizes vibration-induced wear compared to lower grades, extending component life and reducing replacement downtime. Using the correct seal type prevents contamination, which is especially important for off-road motorcycles exposed to dust and moisture. While initial costs may vary by specification, the long-term savings from reduced maintenance and fewer replacements make proper selection a smart investment.
Our ISO 9001-certified processes ensure every bearing meets quality standards, from raw material inspection to final dimension and hardness testing. We stand behind the products we supply with a warranty against manufacturing defects, giving you confidence in your purchase. With access to both international brands like NACHI and domestic options, we can source bearings to your exact requirements, whether you need a single unit or bulk quantities.
