352208 Double Row Tapered Roller Bearing | 352208E / 352208K / 352208TN Features And Application
The 352208 is a high-rigidity double-row tapered roller bearing with standard dimensions of 40×80×30mm. Featuring a symmetrical double-row roller structure, it is professionally engineered to withstand heavy combined radial and bidirectional axial loads, outperforming single-row tapered bearings in stability and load capacity. This bearing effectively restricts two-way shaft displacement, absorbs mechanical shock pressure and minimizes rotational deflection during long-term heavy-load cyclic operation. Widely used in medium and heavy-duty industrial transmission systems, the 352208 series provides three mainstream configurations: 352208E optimized structure model, 352208K solid steel cage model and 352208TN nylon cage model for diverse working conditions.
352208E Optimized Structure Version
352208E is the upgraded universal model of the standard 352208 bearing, manufactured from high-purity chrome bearing steel with integral quenching and ultra-precision grinding. The E-type optimized internal structure enlarges roller arrangement density and contact area, significantly boosting composite load capacity and anti-fatigue performance. Equipped with a high-strength stamped steel cage, it ensures stable roller guidance, low friction loss and consistent medium-speed operation. With excellent versatility and cost performance, this model resists daily mechanical abrasion and fatigue, serving as the preferred standard choice for conventional heavy-duty industrial equipment.
352208K Steel Cage Version
352208K adopts a precision integrally machined solid steel cage, designed for extreme heavy-duty and high-shock working scenarios. Compared with ordinary stamped cages, the solid steel cage features higher structural rigidity, temperature resistance and anti-deformation capability. It maintains accurate roller spacing and structural stability under continuous heavy pressure, frequent impact loads and long-duration uninterrupted operation. This avoids roller offset, abnormal noise and premature wear, greatly improving bearing durability and operational reliability. It is specially built for rigorous heavy-load equipment with harsh and unstable operating conditions.
352208TN Nylon Cage Version
352208TN is fitted with high-toughness PA66 nylon injection molded cage, focusing on low-noise, high-efficiency precision operation. The lightweight nylon cage delivers ultra-low friction coefficient, excellent lubricity and stable anti-fatigue performance. It effectively reduces frictional heat and running noise during medium-speed cyclic operation, improving overall transmission efficiency. With good corrosion resistance and flexible structural toughness, this model adapts to clean, normal-temperature and stable-load environments, providing smooth, quiet and economical operation for precision heavy-load mechanical systems.
Industrial Applications
352208 series double-row tapered bearings are widely used in heavy industrial transmission and positioning systems. 352208E applies to general heavy machinery, medium-sized gearboxes and conventional industrial transmission equipment. 352208K suits mining machinery, construction equipment, hydraulic systems and devices with frequent shock loads. 352208TN is ideal for precision automation machinery and low-noise required industrial processing equipment.
Product Summary: The 352208 double-row tapered roller bearing features powerful bidirectional load capacity and high structural rigidity. Three configurations cover universal standard conditions, heavy-shock harsh scenarios and precision low-noise working environments, offering reliable, long-lasting support for various medium and heavy-duty mechanical transmission systems.
