Applicable Machines and Industries
There are different sorts of machines which often use NU218 bearings, and their functions in these machines and the brands that frequently make such machines:
1.Gearboxes
- Its Role: These bearings are employed in gearboxes to bear shafts that make gears. They take care of immense radial loads and allow axial displacement, preventing intense operation even under serious loads.
- Common Brands: SEW-Eurodrive, Flender (Siemens), Bonfiglioli, Sumitomo, NORD Drivesystems.
2.Electric Motors
- Their Functions: In electric motors, they support rotor shafts with a very high radial capacity to account for possible axial movement due to thermal expansion or other reasons. This guarantees that the motor operates at the highest efficiency levels and extends its life span.
- Common Brands: ABB, Siemens, WEG,Toshiba,Baldor .
3.Pumps
- Its Function: For example, centrifugal pumps or hydraulic pumps are used to support rotating shafts. The bearing holds both radial loads and axial displacements, ensuring correct alignment and efficient pump operation.
- Common Brands: Grundfos, KSB,Sulzer ,Flowserve ,ITT Goulds Pumps .
4.Conveyor Systems
- They Function As Follows: To facilitate this, they have been used for rollers within conveyor systems and on drive components to accommodate their axial movements while supporting radial loads necessary during smooth transportation via a belt system.
- Common Brands : Dematic ,FlexLink,Rexnord ,Interroll,Dorner .
5.Machine Tools
- What It Does: These are fixed on spindles utilized in machine tools like lathes, milling machines, and grinders, e.g., NU 218 bearing. They hold the spindle under load, allowing for some movement along its axis, which is very important for accurate machining processes.
- Common Brands : Haas , DMG Mori ,Mazak ,Okuma ,Makino.
The NU218 Single Row Cylindrical Roller Bearings are vital parts for diverse types of industrial machines such as gears, electrical engines, pumps, belts, lathes and inflators.

Why Amigo NU218 Bearings Are the Top Choice
We’ve recently started using the Amigo NU218 bearings in our gearboxes, and the performance has been outstanding. The bearing handles heavy loads just as efficiently as the SKF NU 218 ECP we previously used. The operation is smooth, and we’ve noticed no difference in quality. Plus, the cost savings with Amigo have been significant, making it a great choice for our business.
Robert L.
After installing the Amigo NU218 bearings in our electric motors, I’m thoroughly impressed with the results. The bearings perform nearly identically to the NTN NU 218 bearings we’ve used before. They provide excellent load handling and run quietly even at high speeds. Amigo bearings have proven to be a reliable and cost-effective alternative without sacrificing quality.
Emily W.
We switched to the Amigo NU218 bearings for our pumps, and they have been performing flawlessly. The quality feels on par with the FAG NU218-E-TVP2 we used in the past. The bearings manage both radial and axial loads without any issues, ensuring our pumps run smoothly and efficiently. The value Amigo offers is hard to beat.
Michael S.
I was initially skeptical about trying a new brand, but the Amigo NU218 bearings have exceeded my expectations. They are just as reliable as the NSK NU 218 bearings we’ve relied on for years. The bearings fit perfectly and have maintained their performance under heavy loads and demanding conditions. Amigo has delivered excellent quality at a more affordable price.
