SS 6903 ZZ/2RS stainless steel deep groove ball bearings

Key selling points and performance advantages: Utilizing a comprehensive high-performance material system and precision manufacturing; bearing rings are precision machined from solid stainless steel bars, with options for AISI 420, AISI 440, AISI 304, and AISI 316 stainless steel to meet corrosion resistance requirements; internally employing G10-grade high-precision steel balls for low friction, low noise, and high stability operation; ultra-thin structure optimizes radial space utilization; deep groove ball raceway design efficiently withstands radial loads and a certain amount of bidirectional axial loads; sealing options include ZZ metal dust caps (suitable for high speeds and high temperatures) or 2RS rubber seals (providing better dust and water resistance).

① The slim design translates into a compact mechanical layout, saving internal space without sacrificing load-bearing capacity and ensuring smooth operation of the transmission system.

② Solid stainless steel bars are sourced from specialized steel mills, and the bearing rings are manufactured through precision machining. This one-stop production model, encompassing raw materials, heat treatment, grinding, and assembly, ensures comprehensive control over bearing quality and consistency throughout the entire process.

③ Flexible configurations are available to adapt to diverse operating conditions: in addition to standard AISI 420 material, higher grades of stainless steel can be selected based on corrosion requirements; lubricating grease options include general industrial grade or NSF-certified food grade; and various options are available for retainer and seal materials.

④ Non-standard customization is supported, such as adding a retaining groove to the outer ring or creating a V-groove on the inner ring to meet special axial positioning or seal installation requirements.
