6205 ETN9 C4 SKF Ball Bearing 25x52x15

PRODUCT DESCRIPTION

6205 ETN9 C4 SKF is a deep groove ball bearing engineered for demanding industrial applications where high speeds, elevated temperatures, and dynamic loads occur simultaneously.

This model belongs to the widely used SKF 6200 series, recognized for versatility and reliability across industrial systems. The ETN9 polyamide cage combined with increased internal clearance C4 makes this bearing particularly suitable for extreme operating conditions where thermal expansion and high rotational speeds must be managed effectively.

Construction and design

The SKF 6205 ETN9 C4 deep groove ball bearing is designed for maximum efficiency and durability.

Key design features:

• single row deep groove ball bearing

• lightweight ETN9 polyamide cage

• increased internal clearance C4

• open design for flexible lubrication

The ETN9 cage reduces friction and inertia, allowing smoother operation at higher speeds. The C4 clearance provides additional internal space, ensuring proper performance under thermal expansion and heavy dynamic loads.

Industrial applications

The SKF 6205 25x52x15 bearing is widely used in applications requiring high thermal resistance and speed capability.

Typical applications include:

• high performance electric motors

• compressors and turbines

• industrial fans and blowers

• production machinery

• systems operating under elevated temperatures

The C4 clearance makes this bearing ideal for environments where standard clearance bearings may overheat or fail prematurely.

Operational advantages

SKF deep groove ball bearings offer several important benefits:

• stable performance at very high speeds

• enhanced resistance to thermal expansion

• reduced friction and energy loss

• extended service life

• reliable operation in demanding conditions

The 6205 ETN9 C4 SKF bearing is often selected as an upgraded solution for high performance industrial systems.

Dimensional compatibility

The 25x52x15 mm bearing size ensures compatibility with a wide range of industrial equipment and standard shaft configurations.
