The NTN K ZW series needle cage is a key component in needle roller bearings: it retains and guides the rollers, allowing high radial loads in tight spaces. It is used in transmissions, electric motors, pumps and agricultural machinery, where precision and wear resistance are critical. MR Accesorios Industriales sells this series with the backing of NTN, a brand MR sells in Buenos Aires, Argentina.

The K ZW series designation reads as follows: the letter K identifies the needle cage; the dimensions that follow indicate bore diameter, outside diameter and width, in millimeters. For example, K12×15×20ZW corresponds to a cage with a 12 mm bore, 15 mm outside diameter and 20 mm width. The ZW suffix indicates a double-row needle configuration, which doubles the radial load capacity. This nomenclature lets you quickly identify the size and variant.

These cages are used in Argentine industries such as automotive, metalworking, food and agriculture. They are found in gearboxes, hydraulic pumps, compressors, electric motors and transmission equipment. Their compact design makes them ideal for spaces where a conventional ball bearing will not fit. In the field, they are found in seeders and harvesters; in manufacturing plants, in conveyors and machine tools.

To select the right cage, take into account the shaft diameter, housing diameter and available width. The K ZW series requires adequate lubrication and precise alignment to prevent premature wear. Assembly must be done with tools that do not damage the rollers or the cage. If the equipment operates under high loads or high speeds, check the clearance and the sealing type of the assembly. Cleaning the parts and the housing is essential before installation.

NTN K ZW series needle cages are interchangeable with those of other brands that follow the same dimensional designation. If you have another brand's part number, we can identify the equivalent. Also, if you have an unidentified part, send us the dimensions and we will tell you the corresponding NTN reference. Interchangeability is based on dimensions and load capacity, not on the manufacturer.
