SKF 6203 2RSLTN9 C3VT162 deep groove ball bearing 17x40x12

Application in electric motors and industrial systems

SKF 6203 2RSLTN9 C3VT162 is a single row deep groove ball bearing with dimensions 17x40x12 mm, designed for demanding electric motor and industrial drive applications. Within the SKF ball bearing range, this configuration combines optimized sealing, increased internal clearance and specialized lubrication.

The 17x40x12 ball bearing is widely used in electric motors, pumps, fans, compressors and other industrial equipment operating under continuous duty. Its design supports stable shaft guidance, low vibration levels and reliable performance in compact assemblies. It can operate as a standalone component or as part of a complete bearing unit installed in a properly selected bearing housing.

2RSLTN9 design, C3 clearance and VT162 grease

The 2RSL designation indicates double sided contact seals that protect the bearing from contamination and retain lubricant inside the raceways. TN9 refers to a glass fiber reinforced polyamide cage, ensuring low mass, reduced friction and stable operation at higher rotational speeds.

C3 internal clearance means increased radial clearance, recommended for applications with elevated operating temperatures or tighter shaft fits. The VT162 grease is specifically developed for electric motor bearings, offering low noise characteristics and extended service life. This combination makes the SKF 6203 2RSLTN9 C3VT162 suitable for industrial applications requiring durability and controlled operating conditions.
