NJ205 25x52x15 Bearing
Single Row Cylindrical Roller Bearing
The NJ205 Single Row Cylindrical Roller Bearing can be used in various industrial applications because it is a versatile and robust component. Its dimensions—bore diameter of 25 mm, outer diameter of 52 mm, and width of 15 mm—make it suitable for such installations, as it has a high radial load capacity and precise axial positioning requirements. Unlike traditional ball bearings, NJ205 has one row of cylindrical rollers that provide larger contact surfaces with raceways. This design allows it to cope with heavier radial loads, making it suitable for use in heavy-duty equipment such as compressors, gearboxes, electric motors, and pumps.

Applicable Machines and Industries
These versatile NJ205 Single-Row Cylindrical Roller Bearings are used in various types of machines, especially where a high radial load-carrying capacity and accurate axial load-handling ability are needed.
1.Gearboxes
- In gearboxes, NJ205 bearings support the shafts, which accommodate the gears. They also take care of the radial loads caused by the rotating gears and can handle axial loads, meaning that the gearbox does not operate smoothly.
- Popular Brands: SEW-Eurodrive, Flender (Siemens), Bonfiglioli, Sumitomo, NORD Drivesystems.
2.Electric Motors
- NJ205 bearings function as supports for rotor shafts in electric motors. This ensures that the shaft rotates without any disturbances while managing the radial forces produced during motor operation, enhancing efficiency and durability.
- Popular Brands: ABB, Siemens, WEG, Toshiba, Baldor.
3.Pumps
- NJ205 bearings provide support for rotating shafts in pumps, both centrifugal and hydraulic. They help manage both types of loads on them so that the shaft is aligned properly for efficient pump operation.
- Popular Brands: Grundfos, KSB, Sulzer, Flowserve, ITT Goulds Pumps.
4.Conveyor Systems
- NJ205 bearings support rollers and drive components in conveyor systems. They help to bear up against radial loads due to material movement, keeping the conveyor operating smoothly and efficiently.
- Popular Brands: Dematic, FlexLink, Rexnord, Interroll, Dorner.
5.Machine Tools
- Machine tools such as lathes or milling machines or grinders have spindles whose functioning depends on NJ205 bearings. Without these components in place, no spindle would be able to rotate under considerable lateral pressure freely, thus giving rise to machining errors associated with tool deflection or vibration at high cutting speeds, causing premature tool failure through breakage or wear-out, therefore affecting machining accuracy and work quality badly.
- Popular Brands: Haas, DMG Mori, Mazak, Okuma, Makino.
6.Compressors
- In compressors, NJ205 bearings support the crankshaft or rotor. Due to the compression process, these components handle radial and axial loads, which makes the operation stable and effective.
- Popular Brands: Atlas Copco, Ingersoll Rand, Kaeser, Sullair, Quincy.

Why Amigo NJ205 Bearings Are the Top Choice
I’ve been using the Amigo NJ205 bearing in our electric motors, and I’m thoroughly impressed. The performance is virtually identical to the SKF NJ205 ECP that we used previously. The bearing runs smoothly and handles high loads effortlessly. Plus, the cost savings with Amigo have been a huge bonus. Definitely a great alternative to the more expensive brands.
John D.
We replaced the bearings in our gearbox with the Amigo NJ205, and the results have been fantastic. It feels just as sturdy and reliable as the NTN NJ205 bearings we’ve used before. The installation was straightforward, and the operation has been flawless since. I’d recommend Amigo bearings to anyone looking for quality at a more affordable price.
Sarah M.
After switching to the Amigo NJ205 bearing for our pump applications, we’ve noticed no difference in performance compared to the INA NJ205-E-XL-TVP2 we previously used. The bearing handles both the radial and axial loads with ease, and it’s been running smoothly for months. The value for money with Amigo bearings is hard to beat.
Robert T.
I was skeptical about switching from the KOYO NJ205R to the Amigo NJ205, but I’m glad I did. The Amigo bearing delivers the same reliability and performance, with no noticeable difference in operation. It’s been running quietly and efficiently in our machinery, and the cost savings have been substantial. I highly recommend giving Amigo a try!
