Decoding FAG 3319-M
- 33Series
- Angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 19Bore
- Bore 95 mm (19 × 5).
- MSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3319 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 3319-M measures 95 mm across the bore and 200 mm across the outside diameter; its width is 77.8 mm (95 x 200 x 77.8 mm).

FAG angular contact bearings are ball bearings with offset raceways, designed to handle radial and axial loads in a single direction. They are typically installed in pairs, either face-to-face or matched, to manage combined forces and add rigidity to the assembly. MR Industrial Accessories LLC supplies this line from Miami, Florida, serving customers throughout the United States and several Latin American countries, with technical guidance to select the right configuration for each application.
The part number follows a pattern: the first three or four digits indicate the series and size, while the suffix specifies internal features. When you see -M, the bearing has a machined brass cage, making it suitable for demanding operating conditions and elevated temperatures. Examples like 3219-M, 3221-M, and 3317-M show how the initial digits define the design and size, and the final digits indicate the dimensional combination. Always use the complete part number to identify the exact variant.
These bearings are found in equipment that experiences significant axial loads in one direction and requires high rotational precision. Common applications include gearboxes, centrifugal pumps, compressors, machine tool spindles, transmission cases, and continuous process equipment. They also appear in mining, cement, steel, and food processing operations, where mounting them in pairs helps distribute axial load and increases support rigidity.
Proper selection depends on several factors: axial load, radial load, speed, and internal clearance. Pair mounting is standard practice—face-to-face for loads in both directions, or matched for greater rigidity. Lubrication, sealing appropriate to the environment, and careful alignment between supports are critical for service life. For equipment running at elevated temperatures, the machined brass cage indicated by the -M suffix is the recommended choice.
When considering replacements, keep in mind that each manufacturer uses its own nomenclature for angular contact bearings. The same size may carry different designations across brands, and suffixes do not always correspond. Therefore, compare dimensions, load capacity, and cage type before substituting one bearing for another. If you are unsure, send us the original part number and we will help you find the equivalent reference among the brands we supply.

Frequently asked questions
- FAG 3319-M bearing: what are its dimensions?
- FAG 3319-M measures 95 mm across the bore and 200 mm across the outside diameter; its width is 77.8 mm (95 x 200 x 77.8 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3319.
- What does the -M suffix indicate on an FAG angular contact bearing?
- The -M suffix means the bearing is equipped with a machined brass cage. This cage type is well-suited for applications involving high speeds, heavy loads, or demanding service temperatures, and it is one of the more robust options in the line.
- How should angular contact bearings be mounted?
- They are usually mounted in pairs—either face-to-face or matched—because each bearing can support axial load in only one direction. The correct configuration depends on the load directions and the rigidity required by the assembly. Always follow the manufacturer's specifications for alignment and clearance.
- Is it possible to replace an angular contact bearing with one from a different brand?
- Yes, provided the main dimensions, load capacity, and cage type are compatible. Since each manufacturer uses its own naming system, do not rely solely on the part number. Send us the original reference and we will help you identify a suitable equivalent.
