NTN 1218 K Self Aligning Ball Bearing
The NTN 1218 K is a self aligning ball bearing built for electricians and maintenance teams who need reliable rotation in power tool assemblies. Its spherical outer race compensates for shaft misalignment, reducing stress on surrounding components during operation. The bearing suits repair work on motors, pumps and gearboxes where precise alignment is difficult to maintain. Supplied as a single unit in a box.
Check shaft and housing dimensions before ordering
Verify that the shaft diameter matches the 90 mm bore and that the housing bore accepts the 160 mm outside diameter. Confirm the 30 mm width fits the available axial space in the assembly. Ensure the operating loads and speeds fall within the bearing’s rated capacity for self aligning types. The red finish helps visual identification during inspection.
Steel construction with self aligning geometry
The bearing uses hardened bearing steel for the inner ring, outer ring and ball complement, giving consistent hardness and wear resistance. Self aligning action allows the inner ring to tilt slightly relative to the outer ring, accommodating minor mounting errors or shaft deflection. This reduces edge loading and extends service intervals in vibration prone equipment. The single piece design simplifies press fitting onto the shaft.

Questions about this item
Does the NTN 1218 K bearing come with a mounting sleeve or adapter sleeve in the box?
The box contains one self-aligning ball bearing with a 90 mm bore, 160 mm outer diameter and 30 mm width; no sleeve or adapter is included.
Should I choose the tapered-bore K version or a cylindrical-bore version for a straight shaft?
The K suffix marks a 1:12 tapered bore that requires an adapter sleeve; for a straight shaft select the non-K version with a cylindrical bore.
What does the 90x160x30 mm size mean when the bearing is installed in a machine?
It fits a 90 mm shaft (with sleeve), sits in a 160 mm housing bore and occupies 30 mm of axial space, allowing ±1.5° self-alignment under load.
