Many buyers struggle with bearing replacements that don’t match dimensions or fail prematurely under heavy loads. Sourcing from multiple suppliers for different brands wastes time, and poor precision often leads to equipment vibration and unplanned downtime. When you need a double row angular contact ball bearing you can trust, getting the right specifications matters more than ever.
The Long Life 3305 Atn9 double row angular contact ball bearings address these challenges with ISO 9001-certified production processes and interchangeable dimensions with major international standards. Our full range of bearing solutions includes this model, designed to handle combined radial and axial loads in applications like steel rolling mills and large gearboxes. With options for both grease and oil lubrication, it adapts to diverse operating conditions while maintaining consistent performance.
This bearing excels in high-load environments with operating temperatures up to standard industrial ranges, making it suitable for continuous-duty machinery. Its double row design provides higher radial load capacity compared to single row alternatives, while the angular contact configuration manages axial forces efficiently. Whether your equipment operates in dusty industrial settings or clean precision environments, the available vibration classes (Z1V1 to Z3V3) ensure smooth operation under varying speed conditions.
Precision rating options from P0 to P2 allow selection based on application requirements—P5 or P4 grades are ideal for high-speed equipment where minimal runout is critical, while P0 suits general industrial use. The 600*800*150 mm specification delivers a robust footprint for heavy machinery, with the width dimension providing stability under moment loads. Vibration class Z3V3 reduces noise and resonance in sensitive applications, while the ability to choose between grease or oil lubrication lets you optimize maintenance intervals for your specific operating conditions.
Choosing the right bearing directly affects your bottom line. A bearing with insufficient precision (like P0 in a high-speed application) can cause premature wear, increasing replacement frequency and labor costs. This model’s adherence to strict dimensional tolerances ensures proper fit, reducing installation time and preventing misalignment-related failures. By selecting the appropriate precision class and vibration rating upfront, you avoid the hidden costs of downtime, secondary equipment damage, and frequent replacements—ultimately lowering your total cost of ownership.
Our production process follows ISO 9001 standards, with raw material inspections and finished product testing for dimensions, hardness, and surface treatment. Each bearing undergoes rigorous quality checks before shipping, and we provide a warranty against manufacturing defects. As a full-service bearing supplier, we offer both our BDL brand and access to international and domestic brands, ensuring you get the right product for your specifications. With substantial inventory, we can fulfill orders quickly, minimizing your equipment downtime.
