The ZZ suffix on an NSK deep groove ball bearing tells you the bearing is a single-row unit fitted with metal shields on both sides. That configuration keeps lubricant in and dust out, which suits moderate-speed operation where radial and axial loads occur together. MR Industrial Accessories LLC supplies this NSK line to customers across the United States and in several Latin American countries, and can help you pin down the right part number for your equipment.
Reading the part number is straightforward once you know the pattern. The series portion sets the cross-section and load capacity, while the digits after the slash give the bore in millimeters. The ZZ ending confirms two steel shields, one per side. Those shields block dust and dirt but do not provide a liquid-tight barrier.
You will find this bearing style in electric motors, pumps, fans, gearboxes, machine tools and power transmission equipment generally. It also shows up in production lines, refrigeration equipment, compressors and agricultural machinery. Because it accepts loads from either direction, it fits a wide range of duties.
Selection comes down to shaft diameter, the radial and axial loads involved, and rotation speed. A ZZ shield works well in dusty conditions; where water or vapors are present, look at other seal options instead. During mounting, use the correct tools, avoid striking the shields, and confirm that shaft and housing are aligned. The bearing arrives pre-lubricated and needs no additional maintenance under normal conditions.
When replacing a bearing from a different brand, match on the main dimensions: bore, outer diameter and width. An NSK ZZ bearing can interchange with another brand's unit that shares those dimensions and the same shield type. Confirm the exact part number and the operating conditions before you swap anything out.

Frequently asked questions
- What does the ZZ suffix mean on an NSK bearing?
- It means the bearing carries two metal shields, one on each side. They keep dust and dirt out and hold lubricant in, but they are not designed for immersion in liquids.
- How do I pick the right NSK deep groove ball bearing?
- Start with the shaft diameter, then factor in loads and speed. The part number encodes the series and the bore size. If anything is unclear, send us the dimensions or part number on WhatsApp and we will help.
- Can NSK ZZ bearings replace other brands?
- Yes, provided the bore, outer diameter and width match and the shield type is the same. Always verify the exact part number. Send us the original number and we will confirm the equivalent.
