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.
What are the dimensions of the 1230-M self-aligning ball bearing?
With a bore of 150 mm, an outside diameter of 270 mm and a width of 54 mm, this design complies with standardised dimensions. The cylindrical bore allows for direct mounting on a shaft with the appropriate tolerances. The double-row bearing is manufactured from standard roller bearing steel 100Cr6.
How does the 1230-M self-aligning ball bearing compensate for misalignment?
The outer ring has a continuous hollow spherical raceway in which the two rows of balls, together with the inner ring, can tilt freely. If shaft deflection or misalignment occurs due to housing tolerances, the bearing adapts with angular movement. This ensures that no impermissible edge stresses are generated on the raceways during operation.
What does the suffix -M mean for this bearing?
The code letter -M denotes a brass cage, which precisely guides the two rows of balls and maintains the correct spacing between them. Brass cages offer high mechanical stability in the presence of vibrations or alternating loads and are suitable for use in a temperature range of -30 to +150 degrees Celsius.
What is the clearance in the 1230-M spherical roller bearing?
The model is supplied with standard radial bearing clearance (CN), which is not specifically indicated in the abbreviation. The standard bearing clearance is designed for conventional mounting fits and moderate operating temperatures, so that once the bearing has been pressed onto the shaft, an appropriate operating clearance remains within the bearing.
How is the 1230-M open pendulum ball bearing lubricated?
As an open roller bearing, this design has no factory-fitted seals or grease fillings. The bearing therefore requires lubrication via the surrounding machine housing using grease or lubricating oil. At the same time, external housing seals must prevent the ingress of dirt particles and moisture, as well as the loss of lubricant.
What is the tolerance class of the 1230-M self-aligning ball bearing?
The bearing complies with tolerance class P0 or PN, which corresponds to the ABEC 1 standard. This standard tolerance is sufficient for the vast majority of industrial machinery applications and defines the permissible dimensional, geometric and running accuracies of the inner and outer rings in accordance with current ISO specifications.
