Decoding FAG NU244-E-M1
- NU 2Series
- Cylindrical roller bearings, NU 2 series. Series differ in outside diameter and width even when the bore is the same.
- 44Bore
- Bore 220 mm (44 × 5).
- E-M1Suffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 244 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG NU244-E-M1 measures 220 mm across the bore and 400 mm across the outside diameter; its width is 65 mm (220 x 400 x 65 mm).

For equipment that runs under heavy radial loads and at high speeds, the FAG NU series cylindrical roller bearing is a common choice. Its cylindrical rollers and cage—brass or polyamide—support precise operation in tough conditions. You will find these bearings in industrial machinery, gearboxes, electric motors and transmission equipment. MR Industrial Accessories supplies this brand.
Reading the NU code helps you specify the right bearing. The letters NU mean the inner ring has no flanges while the outer ring has two, so the bearing can accommodate axial displacement. The following number gives the size and dimension series. The E suffix marks a reinforced design with higher load capacity. M stands for a solid brass cage, and a final code such as M1 identifies a cage variant. So NU238-E-M1 brings together all these traits for a particular size.
These bearings appear in speed reducers, gearboxes, electric motors, pumps, fans and machine tools. Their capacity for heavy radial loads and their rigidity suit gear transmissions and other applications that demand precision and durability. Industries such as food, cement, steel and oil rely on them.
When selecting an NU bearing, consider the radial load, rotation speed and operating environment. Check the sealing: if dust or moisture is present, a sealed or shielded version may be needed. Lubrication—grease or oil—must match speed and temperature. Mounting calls for accurate alignment and cleanliness; poor fitting can shorten service life. The M brass cage withstands high temperatures and vibration.
Interchange is possible with cylindrical roller bearings from other makers if the main dimensions, tolerances and load capacity align. The NU series is standard, but suffixes vary by manufacturer. To swap an FAG for another brand, verify the full part number and technical data. MR Industrial Accessories can advise on compatibility without compromising equipment performance.

Frequently asked questions
- FAG NU244-E-M1 bearing: what are its dimensions?
- FAG NU244-E-M1 measures 220 mm across the bore and 400 mm across the outside diameter; its width is 65 mm (220 x 400 x 65 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 244.
- What does the E suffix mean on an NU bearing?
- The E suffix indicates a reinforced design with higher radial load capacity, achieved through an optimized roller and ring design. Keep this designation when replacing the component to maintain performance.
- How do I choose between an M brass cage and a polyamide one?
- The solid brass cage (M) suits high temperatures and vibratory loads, while polyamide cages are used in lighter applications. The choice depends on your operating conditions. Ask us on WhatsApp and we will advise based on your equipment.
- Can I replace an FAG NU with another brand?
- Yes, if the main dimensions, tolerances and load capacity match. The NU series is standard, but check each manufacturer's suffixes. MR Industrial Accessories helps you validate interchangeability before quoting.
