Core Advantages

High Combined Load Capacity: Effectively bear heavy radial loads and unidirectional axial loads simultaneously, ideal for heavy-duty working conditions.
Separable Design: Inner ring (cone) and outer ring (cup) can be installed separately, simplifying assembly, disassembly, and internal clearance adjustment.
High Rigidity & Impact Resistance: Superior performance under shock loads, vibration, and harsh industrial environments.
Precise Axial Positioning: Accurately control shaft axial play, perfect for precision transmission systems and automotive applications.
Wide Compatibility: Multiple series and metric sizes available, interchangeable with international brands (SKF/NSK/FAG/TIMKEN).
Full Stock & Fast Delivery: Complete range of hot-selling models in stock, supporting bulk orders and fast global shipping.
OEM & Customization: Support special materials, clearances, and non-standard size customization for specific application needs.

Typical Industrial Applications

Widely used in automotive wheel hubs, truck axles, gearboxes, reducers, mining equipment, crushers, vibrating screens, rolling mills, agricultural machinery, construction machinery, pumps, compressors, and other heavy-duty mechanical transmission systems.
