SKF 6305 TN9 C4 Ball Bearing 25x62x17

Deep Groove Ball Bearing for High-Speed Operation

TN9 Cage and C4 Internal Clearance Benefits

Technical Data and Industrial Applications

Main Description:
The SKF 6305 TN9 C4 ball bearing 25x62x17 is a single row deep groove ball bearing engineered for reliable performance in high-speed and elevated temperature environments. With dimensions 25 mm inner diameter, 62 mm outer diameter and 17 mm width, it is widely used in electric motors, pumps, gearboxes and general industrial drive systems.

The C4 internal clearance indicates increased radial clearance compared to standard clearance classes. This makes the bearing particularly suitable for applications where thermal expansion of the shaft or housing occurs during operation. The additional clearance helps prevent preload under high temperatures, ensuring stable rotation and extended service life.

The TN9 designation refers to a glass fiber reinforced polyamide cage. This lightweight cage design reduces friction, supports smooth ball guidance and contributes to lower noise levels. Combined with precision-ground raceways and high-quality steel components, the 6305 TN9 C4 ball bearing provides high durability and consistent load distribution under demanding industrial conditions.

This deep groove ball bearing supports radial loads and moderate axial loads in both directions. It can be installed as a standalone bearing or integrated into a bearing housing or complete bearing unit within industrial assemblies. Its standardized 25x62x17 size allows easy replacement in existing mechanical systems.

For B2B customers, the SKF 6305 TN9 C4 represents dependable quality, predictable operating performance and reduced downtime in critical industrial applications.
