Procuring the right angular contact ball bearings can be challenging—mismatched dimensions leading to installation failures, inconsistent quality causing premature wear, and limited brand options forcing multiple supplier comparisons. These issues often result in costly downtime, especially in critical applications like rolling mills and mining equipment where reliability is non-negotiable.
Our double-row angular contact ball bearings (Model 3314A, 3215A, 3315A, 3216A) address these challenges with precision-engineered design and comprehensive supply capabilities. With ISO 9001-certified production processes and rich stock availability, we ensure you get bearings that meet exact specifications—whether for radial, thrust, or combined loads in automobile transmissions or metallurgical machinery. The 140*80*44.4mm specification, paired with bearing steel construction, delivers durability in high-stress environments.
These bearings excel in applications requiring simultaneous radial and axial load handling, such as rolling mill work rolls and mining conveyors. The unseparated design ensures structural integrity under dynamic loads, while vibration levels (Z1V1 to Z3V3) can be selected based on noise sensitivity requirements. Operating temperatures compatible with both grease and oil lubrication further enhance adaptability across industrial environments.
The double-row configuration provides higher load capacity compared to single-row alternatives, making it ideal for heavy machinery like mine crushers. Precision ratings from P0 to P2 allow customization—P5/P4 grades suit high-speed applications in automobile transmissions, while P0 offers cost-effective solutions for general industrial use. Bearing steel material ensures surface hardness and wear resistance, critical for extending service life in abrasive conditions. The 44.4mm width dimension balances load distribution and installation space constraints, a key consideration in rolling mill assemblies.
Choosing substandard angular contact ball bearings may seem cost-effective initially, but early failures often lead to unplanned downtime, repair labor, and potential damage to adjacent components. Our bearings, manufactured to strict dimensional and hardness standards, reduce these risks by maintaining consistent performance over extended periods. For example, in metallurgical applications, precise P5-rated bearings minimize vibration-induced stress, lowering maintenance frequency and overall operational costs.
Our production processes adhere to ISO 9001 standards, with rigorous testing of raw materials and finished products—including dimensional accuracy, surface hardness, and vibration levels. We provide a warranty against manufacturing defects, ensuring peace of mind for critical applications. With access to a wide range of brands (BDL, NTN, NSK, NMB, Koyo, NACHI, Timken) and rich stock availability, we can fulfill orders of any size, from small batches to large-scale industrial requirements.
Whether you need the 3314A, 3215A, 3315A, 3216A models or other angular contact ball bearings, we can provide competitive pricing and fast delivery. Share your exact model, quantity, and delivery location, and our team will respond within 0.5 hours with a tailored quote.
Q: Do you supply other bearing brands or models beyond those listed?
A: Yes, we offer a full range of bearing types and can source specific brands or models according to your requirements.
Q: How can I confirm if this bearing fits my equipment?
A: Provide your equipment model or existing bearing dimensions (d x D x B), and our technical team will verify compatibility.
Q: What is your warranty policy for these bearings?
A: We provide a warranty against manufacturing defects; specific terms are outlined in each sales contract.
Q: What is the minimum order quantity for these bearings?
A: We support low minimum order quantities, making it feasible for both small-scale trials and large production runs.
Q: How quickly can you ship after an order is placed?
A: Stock items are shipped within 24 hours; delivery time depends on the chosen shipping method (express, air, sea, etc.).
Q: Do you offer OEM or ODM services for custom bearing requirements?
A: Yes, we provide OEM and ODM services to manufacture bearings according to your specific drawings or performance criteria.
