ZIBOO NTN 1218 K Self Aligning Ball Bearing 90x160x30mm

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.
