Decoding SKF NU 344 M
- NU 3Series
- Cylindrical roller bearings, NU 3 series. Series differ in outside diameter and width even when the bore is the same.
- 44Bore
- Bore 220 mm (44 × 5).
- MSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 344 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 344 M measures 220 mm across the bore and 460 mm across the outside diameter; its width is 88 mm (220 x 460 x 88 mm).

SKF NU M series cylindrical roller bearings are built for high radial loads and considerable speeds. The cylindrical rollers make linear contact, spreading the load across a wide surface, which suits demanding applications. MR Industrial Accessories LLC supplies these bearings to customers across the United States, Canada, Mexico and South America. To request a quote, send the part number you need by WhatsApp or email.
Reading the code helps you identify the right bearing. The prefix NU denotes the cylindrical roller bearing type, while the following number indicates the dimension series and bore size. For instance, NU 344 M has 344 as the outer diameter and bore series; NU 348 M uses 348 for a different size in the same series; and NU 419 M, NU 420 M and NU 421 M have 419, 420 and 421 defining specific dimensions. The M suffix is part of the designation and does not affect how the main number is read.
These bearings appear in industrial equipment that must handle significant radial loads, including conveyor belts, mills, centrifugal pumps, industrial fans, reducers and machine tools. They are common in food, cement, mining, steel and petrochemical plants, where robustness and load capacity are critical. The design permits axial shaft movement in one direction, which simplifies mounting in two-support arrangements.
When selecting a bearing, consider the radial load, rotation speed and environmental conditions. Mounting calls for careful alignment between shaft and housing to prevent extra forces. Choose lubrication based on temperature and speed; proper lubrication extends service life. In dusty or wet environments, evaluate additional protections. Always follow the manufacturer's recommendations for fitting and cleaning contact surfaces.
For replacements, equivalent codes from other brands often share the same main dimensions. Interchangeability depends on verifying that bore diameter, outer diameter and width match the original part. If you have a code from another brand or an unidentified sample, MR Industrial Accessories LLC can point you to a compatible alternative. We can also quote the exact SKF code shown on your equipment.

Frequently asked questions
- SKF NU 344 M bearing: what are its dimensions?
- SKF NU 344 M measures 220 mm across the bore and 460 mm across the outside diameter; its width is 88 mm (220 x 460 x 88 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 344.
- What applications use SKF NU M bearings?
- They are found in equipment with high radial loads, such as conveyor belts, mills, pumps, fans and reducers. Industries like food, cement, mining and steel rely on them. The design allows axial shaft displacement in one direction, which helps in two-support arrangements.
- How do I choose the right NU M bearing?
- Consider radial load, rotation speed and environmental conditions. Check bore, outer diameter and width dimensions. Correct alignment and lubrication are key. If unsure, send your equipment data via WhatsApp or email for advice.
- Can I replace another brand's bearing with an SKF NU M?
- Yes, if the main dimensions match: bore diameter, outer diameter and width. Interchangeability is based on those parameters. Send us the original part code or a photo with measurements, and we will identify the equivalent SKF reference and quote it.
