SS 606 ZZ/2RS stainless steel deep groove ball bearings

True all-weather durability, rejecting "fake stainless steel." We guarantee the authenticity of our materials:

AISI 316/304 (Austenitic): For marine engineering and strong acid/alkali chemical environments, providing ultimate rust resistance, with non-magnetic options available.

AISI 440C (Martensitic): Vacuum heat-treated, with a hardness of up to HRC 58+, suitable for high-load, high-wear applications.

"Zero vibration" experience with G10 steel balls: Unlike the commonly used G25/G100 steel balls on the market, we insist on using G10 grade high-precision steel balls across our entire product line. This means tighter tolerances and significantly eliminates microscopic vibrations during high-speed rotation, thus protecting the shaft and bearing housing from wear.

Customized lubrication solutions: Grease determines lifespan. We provide lubrication services using brands such as Mobil and Kluber, including food-grade H1 grease and special waterproof grease, completely solving the emulsification failure problem under water washing conditions.

"We refuse to over-promise and only speak the truth about our materials." In today's mixed stainless steel bearing market, we are one of the few source factories that insist on material spectrum testing. Whether it's the nickel content of AISI 304 or the heat treatment hardness of 440C, we provide genuine material reports. For highly versatile models like the SS 606, we maintain a year-round inventory of semi-finished products, supporting rapid assembly and shipment. We can also precisely adjust the clearance group (C0/C3) based on your speed and load requirements, ensuring the bearings do not seize or produce abnormal noise.
