Decoding FAG NJ2334-EX-TB-M1
- NJ 23Series
- Cylindrical roller bearings, NJ 23 series. Series differ in outside diameter and width even when the bore is the same.
- 34Bore
- Bore 170 mm (34 × 5).
- EX-TB-M1Suffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NJ 2334 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

For machinery that sees constant radial forces, the FAG NJ series cylindrical roller bearing delivers the rigidity and fatigue resistance needed. Its brass cage and refined internal dimensions suit tough industrial duty. MR Industrial Accessories supplies this line to customers across the United States and Latin America, and our team can help you match the right variant to your equipment.
Reading the part number tells you what you are getting. NJ means the inner ring carries one rib while the outer ring has two, so the bearing can guide the shaft axially in a single direction. The digits that follow, such as 2334, 2336, 2338 or 2340, set the size and load capacity. EX points to a higher-capacity layout with optimized dimensions. TB stands for the machined brass cage, and M1 means the bearing has been heat stabilized for elevated temperatures. These details help you order the exact replacement without guesswork.
You will find these bearings in gearboxes, machine tools, industrial pumps, large fans and mining equipment, where radial loads are heavy and stiffness matters. They also appear in oilseed, steel, cement and mineral processing plants. Their construction handles combined loads and resists fatigue, so they can run continuously under severe conditions.
Selection depends on radial and axial load, speed and the surrounding environment. If dust or other contaminants are present, consider a sealed variant. Lubrication must match the operating temperature and speed, and high-viscosity greases or oils are often used. During installation, precise alignment and correct internal clearance adjustment are essential to avoid premature failure.
FAG NJ series bearings interchange with other brands that use the same dimensional and design nomenclature. When you request a quote, confirm tolerances and internal clearance, since these can differ between manufacturers. MR Industrial Accessories can suggest equivalents and options that fit your specific application.
