Decoding FAG NU2264-EX-TB-M1
- NU 22Series
- Cylindrical roller bearings, NU 22 series. Series differ in outside diameter and width even when the bore is the same.
- 64Bore
- Bore 320 mm (64 × 5).
- EX-TB-M1Suffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 2264 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG NU2264-EX-TB-M1 measures 320 mm across the bore and 580 mm across the outside diameter; its width is 150 mm (320 x 580 x 150 mm).

FAG cylindrical roller bearings are built for equipment that carries heavy radial forces at high speeds. The cylindrical roller and brass cage arrangement gives the bearing rigidity and running precision, which is why it shows up in gearboxes, machine tools and other transmission assemblies. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams throughout the United States and in several Latin American countries. If you are unsure which code fits your application, send it over and the team will help you work through the options.
Reading the code tells you a lot before you open a catalog. A NU prefix means the outer ring carries two ribs while the inner ring has none, so the shaft can move axially inside the bearing. The digits after the prefix set the size and the load class. An EX suffix points to a higher-capacity version that uses larger rollers, TB identifies a solid brass cage, and M1 identifies a machined brass cage. Put together, the full designation describes one specific bearing.
You will find these bearings in steel mills, cement plants, mining operations and food processing lines, as well as in speed reducers, pumps, industrial fans and machine tools. The combination of high radial capacity and rigidity suits duties where precision has to hold up under continuous running.
Choosing the right one comes down to radial and axial load, speed and the environment around the bearing. Fit it with the correct tools and check alignment, since misalignment adds stress the bearing was not designed to carry. Grease or oil both work as lubrication, and either one needs to be maintained to get full service life. Where dust, moisture or process contamination is present, look at adding seals. The solid brass cage is strong and supports high speeds, but it depends on a steady supply of clean lubricant.
Bearings from other makers can often replace an FAG unit when the boundary dimensions and load ratings line up. Tolerances and internal geometry are not always identical between brands, so confirm those details before committing to a swap. The safest route is to give the team the complete original code and let them check it against the replacement.

Frequently asked questions
- FAG NU2264-EX-TB-M1 bearing: what are its dimensions?
- FAG NU2264-EX-TB-M1 measures 320 mm across the bore and 580 mm across the outside diameter; its width is 150 mm (320 x 580 x 150 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 2264.
- What does the EX suffix indicate on an FAG cylindrical roller bearing?
- EX marks a higher-capacity design that uses larger-diameter rollers and a reinforced construction, so it can take more radial load than the standard version.
- How do I decide between an NU and an NJ bearing?
- It depends on whether the shaft needs to float. NU bearings have no inner-ring ribs and allow axial displacement, while NJ bearings have one rib and can carry axial load in a single direction. Review the application before choosing.
- What lubrication should I use?
- Speed and temperature drive the decision. Oil suits high speeds, while a quality grease works for moderate speeds. Follow the manufacturer's guidance and keep the lubricant clean.
