6005 2RS C3 SKF® ball bearing 25x47x12

Applications - Electric Motors and Industrial Systems

The SKF 6005 2RS C3 ball bearing 25x47x12 is a single-row deep groove ball bearing designed for applications requiring smooth rotation, reliable sealing, and increased internal clearance. This model is widely used in electric motors, pumps, compressors, conveyors, and various industrial applications where thermal expansion and continuous operation must be considered.

Thanks to its C3 internal clearance, the bearing compensates for temperature-related shaft expansion, ensuring stable performance in demanding operating environments. It can operate independently or as part of a complete bearing unit installed in a properly selected bearing housing.

Advantages - C3 Clearance and Double Sealing

Manufactured by SKF, the 6005 2RS C3 offers precision engineering and consistent quality. The 2RS design features double rubber seals that protect the internal rolling elements from dust, moisture, and contamination while retaining lubrication.

Compared to a standard clearance ball bearing, the C3 version provides improved stability under higher speeds and temperatures. The deep groove geometry ensures balanced load distribution, reduced vibration, and high durability in long-term operation. This makes the bearing suitable for demanding industrial applications where reliability is critical.

Main Description

The SKF 6005 2RS C3 ball bearing 25x47x12 is engineered for systems exposed to continuous loads and elevated operating temperatures. Its increased internal clearance allows safe operation under thermal expansion, preventing excessive preload and premature wear.

As a sealed deep groove ball bearing, it offers efficient protection against contaminants and maintains factory-applied lubrication throughout its service life. When installed within a correctly machined bearing housing, it forms a stable and durable bearing unit capable of delivering smooth, low-noise rotation.

This model is frequently selected by OEM manufacturers, maintenance departments, and industrial distributors seeking high-quality components for electric drives and rotating machinery. The combination of SKF manufacturing standards, C3 clearance, and double sealing ensures consistent performance and extended operational life.
