The NTN AH series is a line of insert bearings built with a hexagonal bore, so they mount directly onto hex-section shafting in bearing units. They suit equipment that needs torque carried through the shaft while still tolerating a small amount of misalignment, including conveyors, agricultural machines and power transmission drives. The sealed construction handles dusty, damp surroundings and moderate loads.

Reading the code is the fastest way to narrow down a replacement. The leading digit tells you which design variant you have, for instance the sealing arrangement or the outer profile. The letters AH follow, and the trailing number gives the hex bore size in inches. Two examples: 1AH04-11/16 is a unit with an 11/16 inch hex bore, and 2AH09-1.1/2 takes a 1.1/2 inch hex bore.

Typical installations are those where the shaft itself is hexagonal: belt conveyors, bucket elevators, mixers and farm equipment. Plants in food processing, cement and material handling rely on this mounting style because it stays put and resists contamination. Moderate radial and axial capacity keeps it useful across machinery that runs in tough conditions.

When choosing an insert, match the hex bore diameter to your shaft and pick the sealing variant that fits the environment. The shaft should be clean and free of burrs, and you should confirm alignment with the housing before tightening. Lubrication and effective sealing are what carry service life. On equipment with vibration, the heavier-duty variant is the safer pick. Our technical team can assist if the choice is not obvious.

Interchange with other brands is possible where the same hex bore nomenclature is used, but check the critical dimensions and the locking method before committing.
