The FAG deep groove ball bearing of the -C-2Z series is a single-row bearing with two protective shields (2Z) and C internal clearance. It is used to support moderate radial and axial loads in equipment rotating at high speeds, where a light seal is needed to retain grease and slow the ingress of dust. It is one of the most widespread designs in Argentine industry due to its low maintenance and ease of mounting.
The designation is read in parts. The base number identifies the size: in the 60 series, for example, 6000-C-2Z, 6001-C-2Z and 6002-C-2Z share the bore diameter and change the outer diameter and width. The letter C indicates the special radial internal clearance, and the suffix 2Z indicates two metal protective shields, one on each side. The complete code goes on the order.
These bearings appear in electric motors, fans, centrifugal pumps, light reducers, machine tools, packaging and conveying equipment. In Argentine plants they are found in food lines, blowers, screw compressors and transmission systems where a compact, low-friction unit is sought. The 2Z shield makes them suitable for environments with dust or fine chips, without the additional friction of a contact seal.
To select well, take into account the radial and axial load it will support, the rotation speed and the type of contaminant. The C clearance is advisable when there are interference fits or thermal gradients between shaft and housing. Lubrication comes from the factory and does not require replenishment in normal service. When mounting, verify shaft alignment with the housing and avoid blows on the shields: an off-center seat shortens the bearing's life.
Among brands, a deep groove ball bearing with the same dimensions and design is interchangeable, as long as the bore, outer diameter, width and type of sealing match. Differences are usually in internal clearance, steel quality and lubricant. If you replace one code with another, compare the suffix letters before mounting. At MR Accesorios Industriales we guide you with the code or model you have at hand.
If you need this bearing, send the complete code by WhatsApp to MR Accesorios Industriales. With the base number and suffixes we identify the design and send you the quote shortly. You can also ask about other sizes of the same series or about sealing variants if your equipment works in a more demanding environment.

Frequently Asked Questions
- What are the dimensions of the FAG 6309-C-2Z bearing?
- The FAG 6309-C-2Z bearing has a 45 mm bore, a 100 mm outside diameter and a 25 mm width (45 x 100 x 25 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6309.
- What does the 2Z suffix mean in a FAG bearing?
- The 2Z suffix indicates that the bearing has two metal protective shields, one on each side. These shields retain grease and slow the ingress of coarse dust, but they do not seal against liquids. It is a light solution, with less friction than a contact seal.
- How do I request a quote for a deep groove ball bearing?
- Write to us on WhatsApp with the complete code, for example
6004-C-2Z, or with the shaft and housing dimensions. With that data we identify the design and reply shortly. If you do not have the code, send a photo of the part and the dimensions. - Can a bearing from one brand be replaced by another?
- Yes, if the main dimensions and the type of design match. A deep groove ball bearing with the same bore, outer diameter and width can be mounted in the same housing. Check that the clearance and sealing suffixes are equivalent before installing it.
