Self-Aligning Ball B. SKF 1200 ETN9

The SKF 1200 ETN9 self-aligning ball bearing has compact dimensions of 10 × 30 × 9 mm and automatically compensates for misalignment caused by shaft deflection during operation.

The SKF 1200 ETN9 self-aligning ball bearing is a double-row rolling bearing made from standard bearing steel (100Cr6) with a common hollow-spherical raceway in the outer ring. This design automatically compensates for misalignment between the inner and outer rings during operation. This design is particularly suitable when elastic deflection of the shaft or misalignment between bearing locations needs to be compensated for. With a bore of 10 mm, an outer diameter of 30 mm and a width of 9 mm, this model is suitable for compact shaft mountings. It is manufactured to tolerance class P0/PN or ABEC 1.

In which installation situations is the 1200 ETN9 self-aligning ball bearing used?

This double-row rolling bearing is suitable for designs where shafts deflect under load or where misalignment is present. Thanks to the hollow spherical raceway of the outer ring, the rolling elements pivot along with the inner ring without causing additional friction. The bearing primarily absorbs radial forces and can withstand moderate axial loads in both directions. A typical application is in bearings with shafts prone to deflection in general mechanical engineering.

What are the distinctive features of the ETN9 polyamide cage?

The suffix ETN9 denotes a lightweight polyamide cage that guides the rows of balls with low vibration and low noise. The material reduces the moment of inertia and promotes smooth running within the permissible temperature range of -30 to +120 degrees Celsius. As this is an open bearing without integrated sealing washers, the lubricant can be selected to suit specific requirements. Designs featuring this open configuration typically utilise an external housing seal to protect against dirt particles.
