DST High-Quality Thrust Ball Bearing – Precision Engineered for Heavy-Duty Performance

Premium Chrome Steel Construction
– Forged from high-grade chrome steel (GCr15) for exceptional hardness (HRC 60-64) and corrosion resistance, ensuring extended durability under extreme loads.
Precision-Ground Raceways
– Meticulously polished surfaces minimize friction and heat generation, optimizing rotational accuracy (±0.002mm tolerance) for smooth operation in high-speed applications.
Optimized Cage Design
– Reinforced brass cage (or stamped steel option) securely retains balls, reducing vibration and wear in repetitive冲击负载 scenarios like mining drills or conveyor systems.
Versatile Industrial Applications
– Ideal for heavy machinery (8319/8320/8322 series fits crushers, excavators), automotive transmissions, and hydraulic pumps requiring axial load support up to 15kN.
Global Bulk Supply Advantage
– Direct factory pricing with MOQ flexibility, backed by ISO 9001-certified manufacturing and 24/7 logistics support for urgent mining or construction projects.
Heat-Treated for Extreme Conditions
– Induction-hardened components withstand temperatures from -30°C to 120°C, perfect for underground mining or marine equipment.
Interchangeable Standard Sizes
– Fully compliant with DIN 711/ISO 104 dimensions for seamless replacement in OEM machinery.
Customizable Options Available
– Request shielded/sealed variants (2RS/ZZ) for dusty or wet environments, with optional lubrication (Grease NLGI #2 or synthetic oil).
