The NTN K ZW series needle cage is a precision component that keeps the needles aligned and separated in roller assemblies, without inner or outer rings. It is used in applications where radial space is limited and high load capacity is required. MR Accesorios Industriales sells it in Buenos Aires, Argentina, with more than 80 years of experience in bearings and power transmission.

The K ZW series designation reads as follows: the letter K identifies a needle cage; the numbers that follow indicate the main dimensions, as in K20×25×40ZWT, where 20 is the bore diameter, 25 the outside diameter and 40 the width. The ZW suffix indicates a stamped steel cage, suitable for high speeds and moderate temperatures. Knowing this nomenclature lets you order the exact replacement part.

These cages are used in agricultural machinery, conveyor belts, gearboxes, pumps, compressors and mining equipment. In Argentina, they are common in the food, petrochemical and automotive industries. Their compact design makes them ideal for gearboxes and spindles where space is critical. MR Accesorios Industriales supplies them for maintenance and equipment manufacturing.

To select the correct cage, check the housing and shaft dimensions and the width of the assembly. Lubrication must be adequate: oil or grease with a viscosity suited to the speed and temperature. Installation requires precise alignment and cleanliness to prevent premature wear. The ZW cage tolerates high speeds, but always within the manufacturer's limits.

NTN needle cages are interchangeable with those of other brands that follow the same dimension standard. If you have another brand's part number, we can identify the equivalent. The K ZW series is complemented by rollers and washers from the same brand. For safe interchangeability, always compare tolerances and cage type.
