SS 6904 ZZ/2RS stainless steel deep groove ball bearings

Key Selling Points and Performance Advantages: Utilizing a rigorous material system and precision manufacturing, the bearings can be made of AISI 420, 440, 304, or 316 stainless steel, providing excellent mechanical strength and meeting various rust and chemical corrosion resistance requirements; internally, it uses G10-grade high-precision steel balls, combined with an optimized deep groove geometry design, ensuring low friction torque, low operating noise, and high rotational stability; the ultra-thin cross-section design ensures load-bearing capacity while maximizing space savings in installation; the standard deep groove ball structure can efficiently withstand radial loads and a certain amount of bidirectional axial loads; the sealing type can be selected as ZZ type (dust covers on both sides with steel plates) or 2RS type (NBR or FKM rubber contact seals on both sides), with the 2RS type offering superior dustproof and low-speed liquid splash protection capabilities, extending lubrication life and maintenance intervals.

The slim design translates directly into a more compact mechanical layout, while the all-stainless steel construction fundamentally enhances durability in harsh environments. Manufacturing advantages ensure the product's inherent reliability. Starting with solid stainless steel bars from professional steel mills, precision machining ensures the continuity of material flow and base strength. A one-stop production model from raw materials to finished products is adopted, with strict control over each process to guarantee dimensional accuracy and performance consistency. Flexible configuration options are provided to adapt to different working conditions. The ring material can be selected according to corrosion requirements, the grease (including food grade) can be selected according to speed and temperature, and the sealing method can be selected according to the protection level. Non-standard processing is supported, such as slotting the outer ring to install O-rings, or machining V-grooves on the inner ring to match the seals, meeting special system sealing requirements.
