SS 629 ZZ/2RS stainless steel deep groove ball bearings

The SS 629 ZZ/2RS stainless steel deep groove ball bearings are a reinforced solution designed for high-load 9mm shaft systems. When the thinner SS 609 cannot meet the load requirements of the equipment, the SS 629, with its 26mm outer diameter and thicker ball wall, provides superior rigidity support. As one of our core strength products, this model is made of AISI 420 martensitic stainless steel as standard, undergoing precision heat treatment and quenching to ensure wear resistance and smooth operation even under high torque and impact loads.

  • SS 629 is primarily used in 9mm shaft equipment where high power transmission stability is required:

    Industrial gearboxes and reducers (Input/Output Shafts)

    Heavy-duty power tools (hammer drills, industrial angle grinders)

    Textile machinery (winding heads, tensioners)

    Fluid pumps (impeller rotor supports)

    Automated conveyor systems (drive rollers)

  • Superior Load Capacity Beyond the 609 Series: SS 629 is designed for robust load resistance. Compared to SS 609, it can withstand higher radial and axial loads. This structural advantage makes it more stable under high-stress conditions such as gear drives or belt tensioning, effectively preventing bearing slippage or breakage.

    AISI 420 Standard Material: Hardness Determines Lifespan (Factory Standard) Our recommended AISI 420 material achieves a hardness of HRC 50-55 after vacuum hardening.

    Abrasion Resistance: It easily withstands wear caused by metal shavings or impurities, with a lifespan far exceeding that of softer 304 stainless steel.

    Value for Money: While ensuring basic rust prevention (resistance to moisture and weak acids), its price is more affordable than 440C, making it the best choice for general industrial applications.

    G10 Grade Steel Balls and Precision Assembly: Our entire product line uses G10 grade stainless steel balls, paired with robust AISI 430 or 304 retainers, ensuring low noise and low vibration even at high speeds.

    Customized Services: While 420 is our main product, we also support order production of AISI 440/304/316 materials for highly corrosive environments such as chemical plants and marine environments, providing you with comprehensive material solutions.

  • SS 629 is typically used in precision motors or imported equipment. Our SS 629 is manufactured with strict control over inner diameter tolerances to ensure a tight fit with your shaft. More importantly, relying on our mature AISI 420 heat treatment process, our delivered products combine the hardness of bearing steel with the rust-resistant properties of stainless steel, helping you find the optimal balance between cost control and product quality.
