How to read FAG N334-E-TB-M1
- N 3Series
- Cylindrical roller bearings, N 3 series. For the same bore, each series has a different outside diameter and width.
- 34Bore
- 170 mm bore: 34 × 5.
- E-TB-M1Suffix
- FAG suffix: it defines the variant (sealing, cage, internal clearance or other features).
N 334 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

FAG cylindrical roller bearings are components with high radial load capacity, designed to withstand high forces and considerable speeds. They are used in applications where precision and rigidity are critical, such as gearboxes, machine tools and industrial equipment. At MR Accesorios Industriales we sell this brand's line, with technical advice to select the correct part number for your application.
The designation of these bearings is interpreted from their letters and numbers. The letter N indicates a single-row cylindrical roller bearing with two ribs on the inner ring and none on the outer ring, which allows axial displacement. The number that follows indicates the dimension series. The suffix E corresponds to a reinforced execution, with higher load capacity. TB identifies a machined brass cage, and M1 indicates a one-piece brass cage. Thus, the part numbers combine these elements to define a specific bearing.
These bearings are used in industries such as metallurgy, cement, mining and machine tools. In Argentina, they are common in speed reducers, milling machine spindles, high-flow pumps and power transmission equipment. Their ability to withstand high radial loads and their rigidity make them suitable for assemblies where precision and durability are required, even under demanding working conditions.
To select the right bearing, take into account the radial load, rotation speed and type of lubrication. The machined brass cage offers good strength and heat dissipation, suitable for high speeds. Mounting must ensure precise alignment between the rings and correct internal clearance; an inadequate fit can reduce service life. Lubrication, whether with grease or oil, must be chosen according to the environment and operating temperature.
Regarding equivalences, cylindrical roller bearings from different manufacturers can be interchanged if dimensions and tolerances match. It is essential to verify the complete part number and technical specifications before replacing one bearing with another of a different brand. Interchangeability is not always direct, since construction details such as the type of cage or the rib design may vary.

Frequently Asked Questions
- What are the dimensions of the FAG N334-E-TB-M1 bearing?
- The FAG N334-E-TB-M1 bearing has a 170 mm bore, a 360 mm outside diameter and a 72 mm width (170 x 360 x 72 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation N 334.
- What does the E suffix mean in an FAG bearing?
- The E suffix indicates a reinforced execution of the bearing, with higher radial load capacity. This is achieved through an optimized design of the rollers and raceways, which allows it to withstand higher forces compared to the standard version.
- How do I choose between a brass cage and a steel cage?
- The machined brass cage (TB or M1) is suitable for high speeds and loads, since it resists friction better and dissipates heat. The choice depends on the operating conditions: consult our technical team to evaluate your case.
- Can I replace an FAG bearing with another brand?
- Yes, if the main dimensions and tolerances match. However, verify the complete part number and specifications, because there may be differences in the cage or internal design that affect performance. We advise you for a safe substitution.
