NSK XZZ series deep groove ball bearings are precision components for supporting radial and axial loads in both directions. Their single row of balls and steel cage design makes them versatile for moderate and high speeds. They are used in electric motors, pumps, fans and transmissions. At MR Accesorios Industriales we sell them and advise you on choosing the right part number.
The XZZ series designation is read from its numbers and suffixes. For example, 601 XZZ, 602 XZZ, 681 XZZ, 682 XZZ, 691 XZZ and 692 XZZ: the digits indicate the size and series type, while the ZZ suffix indicates that the bearing has two metal shield covers. This protection prevents dust from entering and retains lubrication. If the code ends in 2RS, it has rubber seals; without a suffix, it is open. Know the full code to identify the variant.
These bearings are used in a wide variety of industrial equipment in Argentina. You will find them in low and medium power electric motors, centrifugal pumps, fans, compressors, machine tools and transmission equipment. They are also used in the food, textile and automotive industries and in maintenance workshops. Their ability to support combined loads and their low maintenance make them ideal for service and replacement.
To select the correct bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. ZZ sealing is suitable for dusty environments and requires lifetime lubrication. If there is moisture or liquids, 2RS sealing is preferable. Mounting must be done with suitable tools, without striking the raceway directly. Check shaft and housing alignment, and lubricate according to specification. Careful mounting extends service life.
As for equivalences, NSK deep groove ball bearings can be interchanged with those of other brands that follow the same international designation. For example, a 6205 2RS is equivalent among SKF, FAG, NTN and NSK. Always verify tolerances and internal clearance, which can vary by manufacturer. If you have doubts, ask us with the original code and we will tell you the compatible alternative.

Frequently Asked Questions
- What does the ZZ suffix mean on an NSK bearing?
- The ZZ suffix indicates that the bearing has two metal shield covers (one on each side). These covers prevent dust and particles from entering, and retain lubricant. They are suitable for applications where there is no direct contact with liquids.
- How do I choose between an open, ZZ or 2RS bearing?
- The open type allows lubrication and inspection, but requires maintenance. The ZZ is for dusty environments and permanent lubrication. The 2RS has rubber seals that provide better sealing against moisture and liquids. The choice depends on the working conditions.
- Are NSK XZZ series bearings interchangeable with other brands?
- Yes, deep groove ball bearings with an international designation are interchangeable among brands. For example, a 6205 2RS from NSK is equivalent to one from SKF, FAG or NTN. Always verify tolerances and internal clearance, which can vary.
