1208 ETN9 SKF Self Aligning Ball Bearing 40x80x18

PRODUCT DESCRIPTION

1208 ETN9 SKF is a self aligning ball bearing designed to compensate shaft misalignment and ensure stable operation in dynamic industrial environments.

This bearing belongs to the SKF self aligning ball bearing series, widely used in applications where shaft deflection, mounting inaccuracies or structural deformation may occur. The ETN9 polyamide cage improves performance by reducing friction and enabling higher rotational speeds.

Industrial applications

The SKF 1208 ETN9 40x80x18 bearing is commonly used in machinery where alignment cannot be perfectly maintained.

Typical applications include:

• agricultural machinery and equipment

• conveyor systems

• textile and packaging machines

• light industrial drives

• ventilation and fan systems

Thanks to its self aligning capability, this bearing is ideal for applications exposed to shaft deflection or installation deviations.

Construction and design

The SKF 1208 ETN9 self aligning ball bearing features a double row design with a spherical raceway in the outer ring.

Key design features:

• double row self aligning ball bearing

• spherical outer ring raceway

• ETN9 polyamide cage

• open design for flexible lubrication

This construction allows the bearing to automatically adjust to angular misalignment, reducing stress on components and improving system durability.

Operational advantages

SKF self aligning ball bearings provide reliable performance under varying operating conditions:

• automatic compensation of shaft misalignment

• reduced vibration and noise

• lower friction and heat generation

• extended service life

• high speed capability due to lightweight cage

The 1208 ETN9 SKF bearing is a reliable solution for applications requiring flexibility and durability.

Dimensional compatibility

The 40x80x18 mm bearing size is a standardized dimension used across many industrial systems.
