Decoding FAG NU1038-XL-M1
- NU 10Series
- Cylindrical roller bearings, NU 10 series. Series differ in outside diameter and width even when the bore is the same.
- 38Bore
- Bore 190 mm (38 × 5).
- XL-M1Suffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 1038 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

For equipment that carries heavy radial forces at speed, the FAG NU series cylindrical roller bearing is a common choice. Its separable layout simplifies installation and servicing, and the range covers machine tools, gearboxes and pumps where stiffness and accuracy matter. MR Industrial Accessories supplies this brand and can help you match the right part number to your application.
Reading an NU part number is straightforward. The NU letters denote a single-row cylindrical roller bearing whose inner ring has no flanges, so the shaft can move axially. The digits that follow, as in NU406-XL-M1 or NU410-XL-M1, set the size and load rating. XL marks the X-life version, with refined surfaces for longer operating life. M and the trailing digit, such as M1, identify the cage: a machined brass design. Understanding these elements lets you order the exact replacement.
These bearings appear in gearboxes, centrifugal pumps, compressors, machine tools and conveyors, as well as in metallurgical, food and petrochemical plants where radial loads are high and reliability is critical. Their capacity for elevated speeds suits electric motors and spindles. Because they separate, maintenance in continuously running facilities is easier.
Selection depends on the radial load, rotation speed and operating environment. Confirm that shaft and housing tolerances are correct and alignment is precise to avoid extra stress. Lubrication matters: pick a lubricant that matches temperature and speed, and ensure the seal keeps contaminants out. During mounting, use heating or pressing methods that will not damage rollers or raceways. Careful installation extends bearing life.
Bearings from different brands may be interchangeable when principal dimensions and design agree, but tolerances, cage type and load ratings must be checked before substituting one make for another. FAG NU series equivalents exist, yet letter and number codes can differ. A specialist can confirm compatibility. At MR Industrial Accessories we help you make a safe, efficient replacement.

Frequently asked questions
- FAG NU1038-XL-M1 bearing: what are its dimensions?
- FAG NU1038-XL-M1 measures 190 mm across the bore and 290 mm across the outside diameter; its width is 46 mm (190 x 290 x 46 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 1038.
- What does the XL suffix indicate on a FAG bearing?
- XL identifies the X-life execution, which uses design and manufacturing improvements intended to increase service life and load capacity. These bearings typically have optimized contact surfaces and tighter tolerances.
- How do I decide between an NU and an NJ bearing?
- NU has an inner ring without flanges, permitting axial displacement. NJ has a flange on the inner ring, providing axial location in one direction. Your choice depends on whether axial movement must be free or restricted.
- What should I check before mounting?
- Verify shaft and housing alignment, use the correct tools, and follow the maker's guidance for heating or pressing. Proper lubrication and effective sealing are also vital for performance.
