NTN deep groove ball bearings with the ZZ suffix are single-row bearings that carry two metal shields, one on each side. They support moderate radial and axial loads in both directions and are the most widespread option when a simple, low-maintenance bearing suitable for high speeds is sought. They are used in electric motors, pumps, fans, gearboxes and transmission equipment in general.
The designation of these bearings is read in two parts. The four-digit number identifies the size: the first two indicate the diameter series and the last two the bore diameter. Thus, 6008ZZ and 6012ZZ share a series and change the shaft size, just like other part numbers in the same series. The ZZ suffix is what defines the closure: two steel shields, one per side, that retain the lubricant and stop the ingress of coarse dust without adding contact or appreciable friction.
In Argentine industry these bearings appear in general-purpose electric motors, centrifugal pumps, fans and extractors, conveyor belts, machine tools and packaging equipment. They are also found in agricultural implements, compressors and power transmission systems where a compact support is needed, easy to mount and with very little maintenance requirement over the service life of the equipment.
To choose correctly, take into account the type of closure: ZZ is fine in environments with dust and no pressurized liquids, while if there is water or steam a contact seal is advisable. Also check the factory lubrication, the internal clearance and the alignment of the housing and shaft, because a misaligned support shortens the life of the bearing. Mounting is done with a press or puller, never by striking the raceway.
When the customer brings a part number from another brand, interchangeability is resolved by dimensions: bore diameter, outside diameter and width. Deep groove ball bearings of equivalent series between manufacturers usually share those dimensions, and the closure suffix may vary from one brand to another. If the part has no identification, it can be identified by measurement and comparison with the corresponding standard.
If you need an NTN deep groove ball bearing with ZZ closure, send the complete part number via WhatsApp to MR Accesorios Industriales and we will quote it promptly. If you have an unidentified part or a part number from another brand, send us the measurement or the model and we will tell you the corresponding equivalent.

Frequently Asked Questions
- What are the dimensions of the NTN 6011ZZ bearing?
- The NTN 6011ZZ bearing has a 55 mm bore, a 90 mm outside diameter and a 18 mm width (55 x 90 x 18 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6011.
- What does the ZZ suffix mean in an NTN bearing?
- The ZZ suffix indicates that the bearing carries two metal shields, one on each side. They protect against dust and retain the lubricant, without contact with the balls, so they do not increase friction or limit speed.
- How do I send the part number so you can quote it?
- Write to us via WhatsApp with the complete part number, for example 6008ZZ or 6012ZZ, and we will quote it promptly. If you have doubts about the designation, also send us the shaft and housing dimensions.
- Can I replace a bearing from another brand with an NTN one?
- Yes, when the main dimensions match: bore diameter, outside diameter and width. Send the part number of the original brand and we will tell you the equivalent NTN reference so you can confirm interchangeability before mounting.
