Product Description
The 352122 Double Row Tapered Roller Bearing is a metric standard bearing with dimensions 110×180×95mm, featuring a TDO (Tapered Double Outer) integrated outer ring structure for excellent rigidity and stability. It is fully interchangeable with equivalent models from top international brands, sharing the same core dimensions and load capacity for direct replacement in heavy machinery, gearboxes, mining equipment and other demanding applications.
Manufactured in accordance with ISO 9001 standards using high-quality GCr15 bearing steel, our 352122 bearing delivers performance and precision comparable to leading international brands, making it a reliable and cost-effective alternative to SKF, FAG, NSK and other premium bearings. We also provide customized solutions for special requirements including high temperature resistance, high-speed operation and specific clearance settings to meet diverse application needs.

Key Features
- Integrated Double Outer Ring (TDO Design): The outer ring is an integrated double-row structure, which improves the overall rigidity and ensures stable operation under heavy loads.
- Independent Double Inner Rows: Consists of two sets of inner ring assemblies, each equipped with tapered rollers, to bear combined radial and axial loads.
- High-Strength Tapered Rollers: Arranged in a cone angle direction to uniformly distribute stress, enhancing load capacity and service life.
- Precision Cage Guidance: Features a window-type cage structure (stamped steel as standard) to guide rollers smoothly and reduce friction.
- Optimal Internal Clearance: Pre-designed internal structure ensures excellent adaptability to speed, temperature, and fluctuating loads.
