NTN KMJ20×26×13ST needle roller cage

NTN KMJ20×26×13ST belongs to needle roller cage, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for KMJ20×26×13ST and any equivalents.

Needle roller cages in the NTN KMJ‥S series hold the needles apart and keep them aligned inside a bearing, which lowers friction and gives steady running. They suit tight radial envelopes that still have to carry heavy radial loads. MR Industrial Accessories supplies this series and helps you pin down the exact reference before you order.

The code tells you the size once you know how to read it. Take KMJ20×26×13ST: the first figure is the bore diameter, 20 mm; the second is the outside diameter, 26 mm; the third is the width, 13 mm. The ST ending marks a variant defined by NTN, such as a particular material or surface treatment. If you want to go deeper into the nomenclature, the NTN catalog is the reference, or just send us the code stamped on your equipment.

You will find these cages in needle roller bearings running inside transmissions, pumps, compressors, machine tools and mining machinery, among other industrial settings. Because they are compact, they fit where a conventional bearing will not, and they take high radial loads. Automotive, metallurgical and construction operations are typical users, since they depend on the assembly holding up over time.

Choosing the right cage comes down to three measurements: shaft diameter, housing outside diameter and the width you have to work with. The cage also has to suit the needles it will carry and the lubrication method in use. At assembly, check alignment and keep the lips free of impact damage. Correct lubrication and a close fit are what keep the assembly running. Send us your measurements if anything is unclear and we will point you to the right reference.

Cages in the NTN KMJ‥S series can be swapped with equivalents from other makers that work to the same dimensional standard, including SKF, FAG and NSK, provided the dimensions and needle type line up. Confirm the full code and tolerances before committing. If all you have is another brand's code, we can trace the equivalent and quote it.

To get a quote, message us on WhatsApp with the exact code, or with the bore diameter, outside diameter and width. The team answers quickly and can also help if you need a special cage or a specific variant from the series.
