Main description (SEO)

The NTN 6905 C3 ball bearing with dimensions 25 x 42 x 9 mm is a single-row deep groove ball bearing from the thin-section series, designed for applications where compact size, low weight and reliable operation at elevated speeds are essential. Its slim cross-section makes it ideal for modern machinery with limited installation space.

The C3 internal clearance provides increased radial clearance compared to standard bearings, allowing safe and stable operation under higher temperatures and at increased rotational speeds. This design compensates for thermal expansion of the shaft or bearing housing, directly contributing to high durability, reduced friction and extended service life during continuous operation.

This ball bearing is capable of carrying radial loads as well as moderate axial loads in both directions. Thanks to its standardized dimensions, it can be easily integrated into a bearing housing or used as part of a compact bearing unit in various mechanical assemblies. The bearing ensures smooth rotation, low noise levels and consistent performance over long operating periods.

Typical industrial applications include electric motors, gearboxes, pumps, automation equipment, conveyors and precision machinery where space efficiency and reliable operation are critical. The bearing is well suited for OEM manufacturing, industrial maintenance and professional B2B supply chains.

Manufactured in accordance with strict quality standards by NTN, this bearing offers dimensional accuracy, repeatable performance and compatibility with industrial systems requiring dependable components.
