SS 698 ZZ/2RS stainless steel deep groove ball bearings

Key Selling Points and Performance Advantages: Utilizing high-grade stainless steel (such as AISI 420 martensitic stainless steel, with AISI 304/316 austenitic stainless steel options available) ensures mechanical strength and provides excellent corrosion and rust resistance, suitable for humid or mildly corrosive environments; internally, it employs G10-grade high-precision ground steel balls, combined with an optimized deep groove raceway design, achieving extremely low rotational friction, smooth operation, and low noise levels; the 69 series ultra-thin design significantly reduces radial section height, resulting in a smaller outer diameter and width for the same inner diameter, saving axial installation space and supporting miniaturized and compact equipment designs; the classic deep groove ball structure efficiently withstands radial loads and possesses a certain bidirectional axial load-bearing capacity; standard ZZ metal dust cover or 2RS rubber seal ring effectively protects the bearing interior, reducing dust, impurities, and moisture intrusion, extending grease life, and ensuring long-term reliable operation in complex environments.

Choosing SS 698 stainless steel deep groove ball bearings means selecting a rotating solution that provides high stability and reliability for your equipment even in space-constrained conditions. Its core value lies in combining the 69 series' signature slim design, the corrosion resistance of stainless steel, and the smooth operation of precision bearings, making it particularly suitable for modern, compact equipment where both installation space and operating environment are critical considerations. Our manufacturing expertise ensures the superior quality of this bearing. Starting with solid stainless steel bars sourced from specialized steel mills, we employ end-to-end turning rather than tubular stock to ensure a complete material flow and consistent mechanical properties. This vertically integrated production model, from raw materials to finished products, allows us to implement rigorous quality control at every stage of manufacturing—from ring turning and heat treatment to precision grinding. We understand the diversity of industrial applications, therefore SS 698 bearings offer flexible configuration options. You can choose different materials such as AISI 420, 304, or 316 depending on the specific corrosive environment; choose industrial or food-grade grease based on speed and temperature requirements; and choose between ZZ metal dust caps and 2RS rubber seals based on protection level requirements. For special design requirements, we support non-standard processing, such as adding a retaining ring groove to the outer ring or machining a V-groove on the inner ring, to meet specific axial positioning or sealing fit requirements.
