352206 Tapered Roller Bearing | Double Row Heavy-Duty Precision Bearings
The 352206 tapered roller bearing is a high-performance double-row roller bearing, structurally upgraded from single-row tapered models. Featuring symmetric double-row tapered roller arrangement, it efficiently withstands heavy radial load and bidirectional axial thrust, solving shaft offset and reverse thrust issues that single-row bearings cannot handle. This precision bearing delivers ultra-high structural rigidity, strong shock resistance and stable low-to-medium speed operation. With integrated dual-load bearing design, it is specially optimized for heavy mechanical equipment requiring high stability and long-duration continuous operation.
Common Sealing Types And Functional Features
The 352206 double-row tapered roller bearing supports versatile sealing configurations to fit diverse industrial and outdoor working scenarios, boosting operational stability and service life:
Open Type: Standard open-frame structure with large internal grease storage space. It supports full lubrication penetration and easy grease replacement, ideal for heavy industrial equipment with regular maintenance plans and clean, dry workshop environments.
ZZ Metal Shield Seal: Dual-sided precision metal shields adopt non-contact protection design. It blocks dry dust, mineral particles and industrial debris without hindering lubrication flow, perfectly suited for mining equipment, processing machinery and dry indoor heavy-load operating conditions.
2RS Rubber Contact Seal: Upgraded double-layer rubber sealing with tight fitting performance. It effectively isolates splash water, mud, humidity and fine corrosive dust, preventing internal grease deterioration. It is the best choice for outdoor, wet and dusty engineering scenarios with low maintenance frequency.
Bearing Material Grades And Industrial Applications
High Carbon Chrome Bearing Steel: Specialized for heavy-duty roller bearings, featuring ultra-high compressive strength, anti-fatigue and impact resistance. It maintains stable precision under long-term alternating heavy loads, offering excellent durability and cost performance. Mainly used for engineering machinery, truck transmission systems and mining equipment.
304 Stainless Steel: Delivers stable oxidation and rust resistance in conventional humid and open environments. It retains consistent load-bearing performance under medium loads, applicable for general outdoor mechanical equipment and light industrial heavy-duty assemblies.
420 Stainless Steel: Combines high hardness and structural toughness, resisting mechanical impact and mild chemical corrosion. It avoids structural deformation under frequent load changes, suitable for semi-corrosive factory equipment and general precision transmission machinery.
440C Stainless Steel: Features superior wear resistance and dimensional stability, adapting to damp, muddy and moderately corrosive working conditions. It effectively reduces roller wear and fatigue aging for long-cycle continuous operation.
316 Stainless Steel: Premium corrosion-resistant material with outstanding salt spray, acid and alkali tolerance. It operates stably in harsh chemical and marine environments, ideal for marine engineering equipment and chemical heavy-duty machinery.
Core Advantages And Industry Applications
The 352206 double-row tapered roller bearing features bidirectional axial load capacity, doubled structural stability, excellent shock resistance and flexible clearance adjustment. Multiple sealing and material options adapt to dry, humid and corrosive complex working conditions. Widely applied in engineering machinery, heavy trucks, mining equipment, agricultural machinery, industrial gearboxes and marine auxiliary devices, it provides reliable, high-rigidity and long-service heavy-load bearing solutions for modern industrial transmission systems.
