6905RS 25x42x9mm Chrome Steel GCr15 Deep Groove Ball Bearing
⚙️Main features:
Thin-walled characteristic: The 6905RS bearing is a commonly used single-row thin-walled deep groove ball bearing. It belongs to the 6900 thin-walled series, with a width of only 9 millimeters. The difference between the outer diameter and the inner diameter is small, and the radial cross-section is relatively thin. It can provide complete bearing functions in a compact space and achieve compact assembly.

Load capacity: It can efficiently withstand radial loads and also bear a certain degree of axial loads. Its basic dynamic load rating is usually 7.02 kN, and the basic static load rating is approximately 4.3 kN. It is suitable for supporting medium radial and axial loads..
Speed limit: The speed adaptation range is wide. When using grease, the maximum speed is usually around 10,000 rpm, and some products can support up to 16,000 rpm.
Material: Generally, chrome steel GCR15 is used as the base material. For some stainless steel models (such as S6905-2RS), 304 or 440C stainless steel is employed. It is resistant to wear and corrosion and is suitable for special environments such as food and medical industries.
Accuracy grade: Products that meet the ABEC 1/ISO P0 accuracy standard are available, as well as products with higher accuracy such as ABEC 3 and above.
