The MR miniature series consists of stainless steel deep groove ball bearings in imperial sizes. The inner/outer rings and balls are made of 440C stainless steel, offering high hardness, wear resistance, and corrosion resistance. Available configurations include open, ZZ (metal shield), and 2RS (rubber seal) types. Covering a wide range of miniature imperial specifications, these bearings offer smooth rotation, low friction, and low vibration. They are suitable for humid or moisture-prone environments and are widely used in fishing reels, RC models, small motors, medical and beauty equipment, encoders/sensors, and DIY modification parts. Bulk purchasing from stock is available.
ZOTY Stainless Steel Ball Bearings
Stainless steel bearings are widely used in all kinds of general corrosion products. Compared with common chrome steel bearings, stainless steel bearings have stronger rust and anti corrosion performances, Many of our stainless bearings come filled with Food Grade rated grease or Kyodo SRL grease, directly from the factory.
High quality AISI 440C stainless steel bearings resist corrosion and provide exceptional hardness and strength. Features 304 stainless cages and shields; grooved raceways on inner and outer rings sustain moderate axial loads in both directions and radial loads. Available open, sealed (2RS) or shielded (ZZ). ZZ and 2RS are available pre-lubricated Grease.
Benefits:
--Protects against corrosion (all parts made of stainless steel)
--Longer maintenance free lubrication life with Molded-Oil insert
--Maintains a clean environment
--Interchangeable with standard units. Pillow and flange shapes are available
