Finding the right angular contact ball bearing for high-load applications can be challenging. Mismatched precision classes lead to excessive vibration, while substandard materials cause premature wear—costing time and money in replacements. Sourcing from multiple suppliers for different brands only adds complexity to your procurement process.
The 3308A series angular contact ball bearing addresses these challenges with a robust design built for reliability. As a professional bearing supplier with ISO 9001 certified production processes, we ensure each unit meets strict quality standards. Our extensive inventory includes both自有 brand and international models like NTN, NSK, and Koyo, allowing you to source all required bearings from a single partner. Whether used in automobile transmissions or mine conveyor systems, this bearing delivers consistent performance under radial and thrust loads.
This double-row angular contact ball bearing excels in scenarios requiring simultaneous radial and axial load support. With a dimension of 90*40*36.5 mm, it fits seamlessly into standard industrial equipment, making it ideal for rolling mills, metallurgical machinery, and mining operations. The unseparated design ensures structural integrity even under high vibration conditions, while precision ratings from P0 to P2 accommodate applications ranging from general machinery to high-precision systems.
The bearing steel construction provides exceptional hardness and wear resistance, critical for withstanding the rigors of continuous operation in harsh environments. Available with 2RS1 (rubber seals) or 2Z (metal shields) options, it offers flexibility in contamination protection—choose grease lubrication for maintenance-free operation or oil lubrication for high-speed applications. Vibration classes Z1V1 to Z3V3 allow customization based on noise and smoothness requirements, ensuring optimal performance in everything from automated production lines to heavy mining equipment.
Investing in quality bearings reduces long-term costs significantly. A precision-engineered 3308A series bearing minimizes downtime by resisting early failure, unlike cheaper alternatives that often suffer from inconsistent hardness or poor dimensional accuracy. By following ISO 281 standards for bearing life calculation, we ensure our products deliver predictable performance, allowing you to plan maintenance efficiently rather than reacting to unexpected breakdowns. The ability to handle both radial and thrust loads in a single unit also reduces component count, simplifying assembly and reducing potential failure points.
Our production process adheres to ISO 9001 standards, with rigorous testing at every stage—from raw material inspection to final dimensional and hardness checks. Each bearing undergoes surface treatment evaluation to ensure corrosion resistance, and we provide a warranty against manufacturing defects. With rich stock availability, we support both small-scale trials and large-volume orders, delivering by express, road, train, air, or sea based on your timeline requirements. Our 100% on-time delivery rate ensures your production schedule stays on track.
Whether you need the 3308A-2RS1TN9/MT33, 3308A-2Z, or another angular contact ball bearing model, we can fulfill your requirements. Provide the exact model, quantity, and delivery location, and our team will respond with pricing and lead time within 0.5 hours.
