Decoding FAG NUP238-E-M1
- NUP 2Series
- Cylindrical roller bearings, NUP 2 series. Series differ in outside diameter and width even when the bore is the same.
- 38Bore
- Bore 190 mm (38 × 5).
- E-M1Suffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NUP 238 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG NUP238-E-M1 measures 190 mm across the bore and 340 mm across the outside diameter; its width is 55 mm (190 x 340 x 55 mm).

The FAG NUP cylindrical roller bearing is built to carry heavy radial loads while also managing axial forces in both directions, thanks to a fixed flange on the inner ring. You will find it in gearboxes, machine tools and other equipment where stiffness and accuracy matter. MR Industrial Accessories supplies this line as part of its bearing range for customers in the United States and Latin America.
Reading the NUP code helps you pick the right variant. The letters tell you the bearing type: a cylindrical roller design with flanges on both rings. The number that follows, such as NUP238-E-M1, relates to size and load capacity. The E suffix points to a higher-capacity design, and M1 identifies a machined brass cage. These details let you match the exact version to your application.
In industrial settings, these bearings appear in power transmissions, pumps, compressors, fans and mining equipment. They handle high radial loads and moderate axial loads, which suits machine shafts running at medium to high speeds. MR Industrial Accessories provides them for replacement jobs and new projects in production plants, workshops and maintenance operations.
When selecting a bearing, consider the radial and axial loads it will see, the rotation speed and the surrounding conditions. Proper mounting calls for precise alignment between shaft and housing, plus suitable lubrication—grease or oil—depending on how the machine runs. Sealing choices depend on contamination levels; in dirty environments, extra protection is advisable.
Cylindrical roller bearings from different manufacturers can often be swapped if the main dimensions and cage type align. Still, you should check tolerances and internal clearance, since these can differ between brands. For a reliable cross-reference, share the complete part number of the original bearing with our technical team.

Frequently asked questions
- FAG NUP238-E-M1 bearing: what are its dimensions?
- FAG NUP238-E-M1 measures 190 mm across the bore and 340 mm across the outside diameter; its width is 55 mm (190 x 340 x 55 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NUP 238.
- What does the M1 suffix mean in an NUP bearing?
- M1 indicates a machined brass cage. This cage type offers strength for high speeds and loads, so it is worth keeping that feature when you replace the bearing.
- How do I know if an NUP bearing fits my equipment?
- Check the bore, outer diameter and width, and confirm the load direction it supports. The NUP design includes flanges that take axial loads. Send us the original part number and we will help you verify.
- What lubrication do you recommend for these bearings?
- It depends on speed and operating temperature. Lithium grease works for many general applications; oil is often used for high speeds or elevated temperatures. Always follow the equipment manufacturer's instructions.
