The NTN JRZZ deep groove ball bearing is a single-row bearing with metal shields on both sides. It handles moderate radial and axial loads in either direction and suits equipment that needs low maintenance and protection from dust and moisture.
Reading the code: JR identifies NTN's deep groove ball bearing series with a steel cage, while the ZZ suffix means metal shielding on both sides. Those shields keep out external contaminants and hold in the lubricant already applied at the factory.
These bearings fit space-limited assemblies where effective sealing matters. Typical uses include small electric motors, fans, centrifugal pumps, transmission equipment, machine tools and conveying systems. They also appear in food and packaging operations, where cleanliness and humid conditions are part of daily production. The compact envelope helps where axial room is tight.
Selection depends on the radial and axial load the bearing will see, the rotation speed and the surrounding environment. ZZ shielding works well with moderate dust and moisture, but not under immersion. During mounting, align shaft and housing precisely and do not strike the shields. Lubrication is applied at the factory; if you relubricate, use a grease compatible with the original. Poor fitting can shorten service life.
Deep groove ball bearings are interchangeable between brands when bore, outer diameter, width and seal type match. The NTN JRZZ series can be replaced by equivalent bearings that follow the same dimensional nomenclature. Always check tolerances and internal clearance against the application. MR Industrial Accessories can suggest a suitable equivalent if you provide the original part code.

Frequently asked questions
- What does the ZZ suffix mean on an NTN bearing?
- ZZ indicates metal shields on both sides. These shields protect against dust and retain lubrication, but they are not suitable for immersion. This configuration is common in moderately contaminated environments.
- How do I choose the right NTN JRZZ series bearing?
- You need the shaft and housing dimensions, plus the radial and axial loads. Also consider rotation speed and environmental conditions. With that data, we can quote the exact code you need.
- Can I replace an NTN JRZZ bearing with another brand?
- Yes, if the main dimensions (bore, outer diameter and width) and the seal type match. Tolerances and internal clearance must be compatible with your application. Send us the original code and we will indicate the equivalent.
