Smooth alignment with Skf 1308 ETN9

Practical benefits

Automatic compensation for misalignment: Designed with two rows of balls, you easily accommodate shaft deflections and angular misalignments during operation.
Low friction polyamide cage: The lightweight polymer cage reduces internal friction and heat generation, allowing you to run smoothly at high speeds.
Robust and precise fit: Built with a 40 mm cylindrical bore and bearing steel, you maintain dependable stability across demanding mechanical assemblies.

In a nutshell

The right choise for

With the Skf 1308 ETN9, you easily accommodate shaft deflections and angular misalignments across your mechanical assemblies. This double row self-aligning ball bearing features a 40 mm cylindrical bore, a 90 mm outer diameter, and a width of 23 mm. Its spherical outer raceway automatically compensates for misalignment between the shaft and housing, preventing premature wear under load. The lightweight polyamide cage reduces internal friction and heat build-up, ensuring smooth, quiet operation at high speeds. Designed as an open bearing with standard normal radial internal clearance CN, it delivers dependable stability for conveyor systems, ventilation fans, agricultural machinery, and industrial gearboxes.
