Self-Aligning Ball B. FAG 1230 -M

The FAG 1230-M double-row self-aligning ball bearing, measuring 150 × 270 × 54 mm, compensates for misalignment via a common hollow-spherical outer ring raceway.

The FAG 1230-M double-row self-aligning ball bearing is suitable for shaft mountings with deflection or misalignment between the inner and outer rings. The spherical raceway in the outer ring allows the rolling elements to adjust their angular position. This model has a cylindrical bore of 150 mm, an outer diameter of 270 mm and a width of 54 mm. Manufactured from standard roller bearing steel 100Cr6, the open design covers an operating temperature range of -30 to +150 degrees Celsius.

In which installation scenarios does the 1230-M self-aligning ball bearing compensate for misalignment?

This rolling bearing is used in bearing arrangements where shaft deflection or angular misalignment between the inner and outer rings occurs. As the outer ring has a continuous spherical raceway, the two rows of balls continue to rotate unhindered even in the presence of static and dynamic angular misalignments. This design features standard radial clearance and is suitable for cylindrical shaft seats. The self-aligning geometry counteracts disruptive edge pressures on the rolling elements.

What is the function of the brass cage in the 1230-M self-aligning ball bearing?

The suffix ‘-M’ indicates a brass cage. This cage material is characterised by high resistance to vibrations and acceleration forces and performs well under demanding lubrication conditions. As this is an open bearing without integrated sealing washers, installation requires an external housing seal and a targeted supply of lubricant. Designers should also note the tolerance class P0/PN (ABEC 1) when designing suitable bearing seats in accordance with standard tolerances.
