Decoding FAG NU336-E-TB-M1
- NU 3Series
- Cylindrical roller bearings, NU 3 series. Series differ in outside diameter and width even when the bore is the same.
- 36Bore
- Bore 180 mm (36 × 5).
- E-TB-M1Suffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 336 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG NU336-E-TB-M1 measures 180 mm across the bore and 380 mm across the outside diameter; its width is 75 mm (180 x 380 x 75 mm).

For equipment that runs under continuous radial load, the FAG NU series cylindrical roller bearing is a common choice. Its cylindrical rollers and machined brass cage support precise rotation in tough industrial service. You will find this series in gearboxes, pumps, compressors and transmission systems where rigidity and load capacity matter. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and Latin America.
Reading the NU code helps you confirm what you are ordering. The letters NU mean a cylindrical roller bearing with two ribs on the outer ring and a rib-free inner ring, so the shaft can move axially. The digits after NU give the dimension series, as in NU248-E-TB-M1 or NU260-E-TB-M1, where it may be two or three digits. The E suffix marks a higher load capacity design. TB refers to a machined brass cage guided by the rollers, and M1 indicates a one-piece brass cage.
These bearings suit gearboxes and gear units, centrifugal pumps, compressors, machine tools and mining equipment. They also appear in conveyors, mills and power transmission systems in steel and cement plants. The combination of high radial load capacity and rigidity makes them useful where precision and long service are required.
Selection starts with the radial load, the rotation speed and the operating environment. If contaminants are present, add sealing protection. Mounting must be aligned accurately to avoid added stress. Grease or oil lubrication should match the application, and internal clearance must be checked against the assembly. Verify how the bearing interacts with adjacent components before installation.
NU series bearings follow a standardized designation, so they can be interchanged between manufacturers that use the same system. Still, tolerances and load ratings can differ because of materials and heat treatment. When replacing a bearing, compare the main dimensions and operating conditions to confirm equivalent performance.

Frequently asked questions
- FAG NU336-E-TB-M1 bearing: what are its dimensions?
- FAG NU336-E-TB-M1 measures 180 mm across the bore and 380 mm across the outside diameter; its width is 75 mm (180 x 380 x 75 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 336.
- What does the E suffix mean in NU bearings?
- The E suffix identifies a design with higher load capacity, achieved through optimized rollers and raceways. It can take higher radial loads than the standard version.
- How do I choose between an NU and an NJ bearing?
- The difference is in the ribs. NU has two ribs on the outer ring and none on the inner ring, allowing axial displacement. NJ has one rib on the inner ring, which provides axial location in one direction. Choose based on whether you need axial freedom.
- What lubrication do you recommend for these bearings?
- It depends on speed and operating temperature. Oil suits high speeds, while high-quality grease works for moderate speeds and high loads. Follow the manufacturer's specifications and keep lubrication maintained to extend service life.
