When an assembly has to absorb thrust but leaves almost no room along the shaft, the INA AXW series needle thrust bearing is one of the parts maintenance and design teams reach for. The cylindrical needle arrangement keeps the section height low while handling axial force in one direction, which suits gearboxes, clutches, pumps and machine tools where precision matters. MR Industrial Accessories supplies this INA line to customers throughout the United States and in several Latin American countries.

Reading the code takes only a moment. The letters AX mark the part as a thrust bearing and the W tells you it is a needle thrust washer. The figure that follows gives the nominal bore of the shaft or washer, depending on which variant you are holding. Common sizes in this family run AXW10, AXW12, AXW15, AXW17, AXW20, AXW25, AXW30 and AXW35. Thin section, high axial capacity in a single direction: that combination is what defines the series.

Selection starts with three inputs: the axial load the part will see, the rotational speed, and how it will be lubricated. The seating faces that support the washers need to be ground and square to the shaft, otherwise the needles work under eccentric load. Grease or oil both work, as long as a proper film forms between the needles and the raceways. Keep the mounting area clean and the alignment true; pressing a bearing on by force can ruin the needles or the washers. Our technical team can walk you through any doubtful point.

Typical installations include machine tools, gearboxes, clutches, pumps, compressors and power transmission equipment, along with agricultural and road machinery maintenance and production line assemblies where axial space is at a premium. Because the profile is so shallow, a designer can often drop this bearing in where a larger thrust bearing would not fit.

On interchangeability, similar designations exist from other manufacturers, but the washer geometry, needle count and heat treatment are not always the same. Compare exact dimensions and load ratings before substituting one part for another, and ask a specialist when the data is unclear. We can help you confirm the match.
