The NTN K ZW series needle cage holds and guides the rollers inside a needle roller bearing, which lets the assembly carry radial loads in a small envelope. You will find this type of component in gearboxes, electric motors, pumps and agricultural equipment, where alignment and lubrication conditions matter. MR Industrial Accessories supplies this series as part of its bearing and power transmission range for customers in the United States and Latin America.

Reading the code is the fastest way to confirm what you need. The K stands for needle cage. The three figures that follow are given in millimeters and correspond to bore, outside diameter and width, in that order. A cage marked K12×15×20ZW, for instance, has a 12 mm bore, a 15 mm outside diameter and a 20 mm width. The ZW ending tells you the cage carries two rows of needles rather than one.

Because the cage is thin-walled, it suits locations where a conventional ball bearing would take up too much room. Typical applications include gearboxes, hydraulic pumps, compressors, electric motors and transmission units, as well as conveyors, machine tools and harvesting equipment. In each case the surrounding shaft and housing do the load-bearing work, so their condition matters as much as the cage itself.

When specifying a replacement, note the shaft diameter, the housing bore and the width available in the assembly. Needle cages of this type depend on proper lubrication and accurate alignment; without them, wear appears early. During installation, use tools that will not mark the rollers or deform the cage. On equipment running at high speed or under heavy load, check the internal clearance and the sealing arrangement before fitting new parts, and clean both the components and the housing first.

Cages built to the same dimensional designation can be used across brands. If the part in your hand carries another manufacturer's number, we can cross it to the NTN reference. If the marking is gone, send the bore, outside diameter and width and we will identify the cage that matches. Interchange is decided by dimensions and load capacity, not by whose name is on the box.
