352207 Double Row Tapered Roller Bearing | 352207E / 352207K / 352207TN Features And Application
The 352207 is a high-performance double-row tapered roller bearing with standard dimensions of 35×72×28mm. Designed for heavy combined radial and bidirectional axial loads, this double-row structure delivers much higher rigidity and load capacity than single-row tapered bearings. It effectively limits bidirectional shaft movement, resists shock pressure and reduces rotational deflection during continuous heavy-load operation. Widely used in medium and heavy-duty transmission machinery, the 352207 series includes three mainstream configurations: 352207E optimized structure type, 352207K steel cage type and 352207TN nylon cage type, covering standard and complex industrial working conditions.
352207E Optimized Structure Version
352207E is the upgraded enhanced model of the standard 352207 bearing. It adopts high-purity chrome bearing steel with integral quenching and precision grinding treatment. The E-type optimized internal design increases roller arrangement density and contact area, greatly improving composite radial and axial load capacity and fatigue resistance. Equipped with a high-strength stamped steel cage, this model features stable guidance, low friction and excellent versatility. It supports medium-speed continuous cyclic operation, provides outstanding cost performance and is the most widely used universal version for conventional heavy-duty industrial equipment.
352207K Steel Cage Version
352207K features an integral machined solid steel cage for heavy-duty and high-stability scenarios. Compared with stamped cages, the solid steel cage boasts higher structural rigidity, anti-deformation performance and impact resistance. It maintains precise roller spacing under heavy pressure and frequent shock loads, avoiding roller offset and abnormal wear. With excellent thermal stability and mechanical strength, the 352207K runs stably under long-duration high-load operation, effectively extending service life and reducing equipment failure rates, ideal for rigorous heavy-duty working environments.
352207TN Nylon Cage Version
352207TN adopts high-toughness PA66 nylon injection cage, focusing on low-noise and high-efficiency operation. The lightweight nylon cage features ultra-low friction coefficient, good lubricity and outstanding anti-fatigue performance. It effectively reduces running noise and frictional heat during medium-speed operation, improving mechanical transmission efficiency. With fine corrosion resistance and flexible structural toughness, this model suits clean, normal-temperature and stable-load working conditions, providing quiet, smooth and economical operation for precision heavy-load transmission systems.
Industrial Applications
352207 series double-row tapered bearings are widely applied in heavy industrial transmission fields. 352207E is suitable for general heavy machinery, medium-sized gearboxes and conventional industrial transmission equipment. 352207K fits mining machinery, construction equipment and hydraulic devices with frequent shock loads. 352207TN is commonly used for precision industrial machinery and low-noise required automation equipment.
Product Summary: The 352207 double-row tapered roller bearing offers superior bidirectional load capacity and high rigidity. With E universal type, K heavy-duty steel cage type and TN low-noise nylon cage type, the series fully covers conventional, heavy-shock and precision working scenarios, serving as a reliable core component for medium and heavy-duty mechanical systems.
