When a roller assembly has no room for inner or outer rings, a needle cage keeps the rolling elements separated and aligned. The NTN K ZW series is built for exactly that: tight radial spaces where load capacity still matters. MR Industrial Accessories supplies this series to maintenance and purchasing teams across the United States and Latin America.

Reading the code helps you order the right cage. The K at the start means needle cage. The numbers that follow give the main dimensions, so K20×25×40ZWT translates to a 20 mm bore, a 25 mm outside diameter and a 40 mm width. The ZW suffix tells you the cage is stamped steel, a construction that handles high speeds and moderate temperatures. Once you know this pattern, matching a replacement becomes straightforward.

You will find these cages in agricultural equipment, conveyors, gearboxes, pumps, compressors and mining machinery. Their compact profile suits gearboxes and spindles where every millimeter counts. MR Industrial Accessories supports both maintenance work and equipment manufacturing with this series.

Selection starts with the housing and shaft dimensions and the width of the assembly. Lubrication also matters: choose oil or grease with a viscosity that matches the speed and temperature of the application. During installation, alignment and cleanliness are critical to avoid premature wear. The ZW cage can run at high speeds, but stay within the manufacturer's limits.

NTN needle cages interchange with other brands that follow the same dimension standard. If you only have another manufacturer's part number, we can identify the equivalent. Rollers and washers from the same brand complete the K ZW series. Always compare tolerances and cage type before substituting.
