Description
Double-row angular contact ball bearings, series 3300 (FAG). It is the medium series of double-row angular contact ball bearings, sturdier than the 3200, for heavier combined loads. This page lists 14 codes, with bores from 15 to 40 mm: choose the code from the menu above.
- TypeDouble-row angular contact ball bearings
- Series3300
- Bore dfrom 15 to 40 mm
- Outer diameter Dfrom 42 to 90 mm
- Codes14
- BrandFAG
Features
- They take combined loads: radial and axial in both directions
- The space of one bearing instead of a pair of angular contact bearings
- Rigid shaft support with little axial play
- Available open or sealed (2RS) where shown in the code
Typical applications
Operating conditions
| Loads | Combined: radial and axial in both directions |
|---|---|
| Speed | Medium |
| Misalignment | Not tolerated |
| Lubrication | Grease or oil |
| Temperature | Usually up to about +120 °C; with seals about +100 °C |
Advantages
- Axial loads in both directions with a single bearing
- High rigidity in little space
- Simpler mounting than a pair of angular contact bearings
Limitations
- Sensitive to misalignment
- Lower speeds than single-row deep groove ball bearings

Available codes
The d × D × B dimensions (bore, outer diameter, width) of each code appear in the "Sizes" menu; variants with a suffix (2RS, ZZ, C3…) are listed in the series menu.
Technician's tipMount it with a precise fit on shaft and housing: it is a rigid bearing, and even slight misalignment shortens its life.
Temperatures and speeds are general guidelines for standard steel bearings: for special conditions ask us for the manufacturer's data.

Equivalent designations across brands: 2RS (rubber seals on both sides) = 2RSR FAG = 2RS1 / 2RSH SKF = DDU NSK = LLU NTN; 2Z (metal shields on both sides) = 2ZR FAG = 2Z SKF = ZZ NSK, NTN and Koyo; C3 = increased radial internal clearance, the same for all brands.
