Double Row Angular Contact Ball Bearings

Double row angular contact ball bearings are high-precision integral rolling bearings designed with dual symmetric ball rows, capable of bearing combined radial loads and bidirectional axial loads simultaneously. Different from single row angular contact ball bearings that only support one-way thrust force, this integrated double row structure provides higher rigidity, better running stability and more compact installation space, which effectively avoids assembly errors caused by paired single row bearing installation. Manufactured strictly in accordance with ISO international standards, our double row angular contact ball bearings feature complete interchangeability, stable high-speed performance and ultra-low vibration, becoming the preferred solution for modern precision mechanical transmission systems.

We supply a full range of standard double row angular contact ball bearing models, covering the most popular industrial 3200 series and heavy-duty 3300 series to meet diverse load and precision requirements. The mainstream product lineup includes 3200, 3201, 3202, 3203, 3204, 3205, 3206, 3207, 3208, 3209, 3210 and extended 3211, 3212, 3214, 3216 specifications for general industrial applications. For heavy load and high-rigidity working conditions, our complete 3300 series covers 3302, 3303, 3304, 3305, 3306, 3307, 3308, 3309, 3310 and larger size models, delivering enhanced load capacity and structural stability. All series support open type, ZZ metal shielded type and 2RS rubber sealed type, with standard P0, high precision P6 and P5 grade options available.

All double row angular contact ball bearings are made of high-purity carbon chromium bearing steel and processed through multiple precise heat treatment procedures, achieving excellent surface hardness, wear resistance and fatigue resistance. Optimized raceway grinding and high-precision steel ball matching ensure smooth rotation, low noise and low friction coefficient during continuous high-speed operation. The reinforced stamped steel or nylon cage effectively prevents deformation and displacement under long-term alternating loads. Sealed versions are pre-filled with high-temperature and anti-aging lubricating grease, realizing long-term maintenance-free operation while blocking dust, moisture and particulate impurities, greatly extending bearing service life in harsh working environments.

Thanks to their outstanding mechanical performance, our full-series double row angular contact ball bearings are widely applicable in precision machine tool spindles, automotive transmission assemblies, wheel hub systems, automated production equipment, gearboxes, fans, compressors, textile machinery, packaging machinery, agricultural machinery and engineering equipment. The compact structure and superior bidirectional bearing capacity make these bearings highly suitable for mechanical equipment that requires high positioning accuracy, stable high-speed operation and limited installation space.

As a professional factory supplier, we maintain sufficient stock for all conventional 3200 and 3300 series double row angular contact ball bearings, supporting sample orders, small-batch customization and large-scale bulk wholesale. We provide flexible global shipping solutions including sea freight, air freight and international express, ensuring fast and safe delivery for worldwide clients. Custom services such as non-standard size processing, special clearance adjustment, exclusive logo printing and customized packaging are available to meet personalized OEM and ODM demands. Every product passes strict quality inspection and complies with ISO9001 certification, providing reliable and cost-effective bearing solutions for global industrial customers.
