Finding the right angular contact ball bearings for your equipment can be a hassle. Many buyers face issues with mismatched dimensions leading to installation delays, or poor-quality bearings that wear out quickly, causing unexpected downtime. Sourcing from multiple suppliers to compare brands and lead times only adds to the complexity.
Our double-row angular contact ball bearings address these challenges head-on. With ISO 9001-certified production processes and a wide range of international brand compatibility, we ensure you get bearings that meet precise specifications. Available in models 3317A, 3218A, 3318A, and 3219A, these bearings are designed for applications like automobile transmissions and rolling mill equipment, where reliable radial and thrust load handling is critical.
These angular contact ball bearings excel in conditions requiring simultaneous radial and thrust load support. The unseparated design ensures structural integrity during high-speed operation, while the double-row configuration provides enhanced rigidity. Whether used in mining conveyors or metallurgical machinery, they maintain stability even under variable loads and operating temperatures.
Manufactured from high-grade bearing steel, these bearings offer excellent durability and wear resistance. The precision rating options (P0 to P2) allow you to select the right balance between performance and cost for your application. Vibration grades Z1V1 to Z3V3 ensure smooth operation, reducing noise and extending equipment life. The 170*90*55.6mm specification provides a standard size that fits many industrial setups, ensuring easy replacement and interchangeability with major international standards.
Selecting an incorrect bearing can lead to more than just frequent replacements. Early failure due to material or precision issues can damage adjacent components, increase maintenance labor costs, and result in unplanned production downtime. Our bearings, with their robust construction and strict quality control, help minimize these risks, lowering your total cost of ownership over time. By following industry standards for load capacity and fatigue life, they provide reliable performance you can count on.
We stand behind our products with a comprehensive quality assurance process. All bearings undergo原材料检验 and成品检测 for dimensions, hardness, and surface treatment. Our ISO 9001 certification ensures consistent production standards from start to finish. We offer a warranty against manufacturing defects, and our rich stock availability means you can get the bearings you need without unnecessary delays.
Whether you need the 3317A, 3218A, 3318A, or 3219A model, or any other bearing type, we’re here to help. Provide us with your specific model, quantity, and delivery location, and our team will promptly send you a competitive quote. The sooner you confirm your order, the sooner we can arrange shipment to keep your operations running smoothly.
