Smooth rotation under misalignment with Skf

Practical benefits

Automatic alignment error compensation: You accommodate shaft deflections and angular misalignment effortlessly without increasing internal friction or stress.
Reduced friction and heat: The lightweight polyamide cage ensures you achieve smooth operation with minimal running temperature at higher speeds.
Straightforward cylindrical mounting: With the standard 20 mm cylindrical bore, you fit the bearing directly onto straight shafts without hassle.

In a nutshell

The right choise for

With the Skf 1304 ETN9 double row self-aligning ball bearing, you keep rotating machinery running smoothly and reliably, even when alignment tolerances are demanding. This open bearing with dimensions of 20X52X15 mm automatically compensates for angular misalignment and shaft deflections relative to the housing. Thanks to the lightweight glass-fibre reinforced polyamide cage, you benefit from reduced friction and minimal heat generation at higher speeds. The cylindrical 20 mm bore enables direct and straightforward mounting onto straight shafts, helping you prevent premature bearing wear in industrial transmissions, conveyor systems, and agricultural machinery.

Product description

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.
