SS 6207 ZZ/2RS stainless steel deep groove ball bearings

1. Dual Material Options (420/440) for Heavy-Duty and Harsh Conditions
Mainly manufactured using AISI420 stainless steel, offering balanced hardness and strong wear resistance to meet standard heavy-duty industrial needs. Upgradeable to AISI440 high-hardness stainless steel, providing enhanced wear and deformation resistance, suitable for harsh conditions with high loads, high friction, and moderate corrosion. Flexible material options adaptable to different application scenarios.

2. Large Inner Diameter, High Rigidity Structure for Heavy-Duty Fatigue Resistance and Deformation Resistance
The 35mm large inner diameter design significantly improves overall structural rigidity, allowing it to withstand stronger radial and axial combined loads. Under long-term continuous heavy loads and frequent start-stop conditions, it is less prone to overheating, deformation, and jamming, resulting in a service life far exceeding that of conventional small-diameter bearings.

3. G10 Grade Precision Steel Balls for Low-Loss and Quiet Operation
Standard configuration includes G10 grade high-precision stainless steel balls with compliant roundness and surface finish. Low rolling resistance, low temperature rise, and low operating noise effectively reduce equipment energy consumption and improve overall machine smoothness and service life.

4. Customized Seals + Dedicated Greases: Enhanced Protection for All Scenarios
Sealing options include ZZ metal dust covers, 2RS nitrile rubber (general-purpose oil-resistant), and fluororubber (high-temperature resistant, acid and alkali resistant), effectively preventing the intrusion of dust, sewage, and chemical media. Grease options include heavy-duty industrial greases, food-grade greases, and high-temperature greases, meeting the standards of heavy machinery, food, chemical, and other industries.

5. One-Stop Precision Production: Stable and Reliable Batch Quality
We source high-quality steel and focus on self-management of the entire process of bearing machining, heat treatment, precision grinding, and assembly, eliminating outsourcing. This ensures highly consistent dimensional accuracy and operational performance, making it suitable for long-term batch supply to large equipment manufacturers.

We focus on the R&D and mass production of SS 6207 large-size heavy-duty stainless steel bearings. Using high-quality AISI420/AISI440 steel as raw materials, we strictly control rigidity and load-bearing performance through one-stop precision machining. Combined with G10-grade precision steel balls and customized sealing and lubrication solutions, we can meet the long-term stable operation requirements of high-power, heavy-duty industrial equipment. We provide stable batch supply, flexible material customization, and efficient delivery services.
