The NSK ZZ deep groove ball bearing is a single-row bearing fitted with two sheet metal shields that keep lubricant in and dust out. It suits electric motors, home appliances, portable tools, and light transmissions where high speed and low maintenance are priorities. MR Industrial Accessories LLC supplies this line and assists customers in selecting the correct size for their equipment.
The part number combines a basic three- or four-digit number with the ZZ suffix. The digits describe the size: the first ones relate to the bore diameter and the last to the diameter series, so the number changes the outer size within the ZZ series. The ZZ suffix stands for double sheet metal shield; a final 1 may indicate a shield variant. Send the complete code by WhatsApp or email and we will quote the exact size.
Typical applications include single-phase and three-phase electric motors, fans, small centrifugal pumps, compressors, sewing machines, power tools, and gym equipment. In industrial settings, they appear in packaging lines, light conveyor belts, and machine tools. The shielded construction handles dust, fine chips, and moderate humidity, provided there is no direct contact with water or aggressive vapors.
When selecting, consider speed, load, and contamination. ZZ shields create less friction than rubber seals, making them suitable for high speed, but they do not retain humidity as well. Confirm that the bore, outer diameter, and width match the housing and shaft. During mounting, apply force to the fixed ring and use a suitable impact tube. Proper lubrication and precise alignment extend bearing service life.
For a replacement from another brand, the main dimensions and closure type must match. Equivalent series from different brands usually share dimensions, but internal clearance or lubricant may differ. Provide the old code or the shaft and housing dimensions, and we will identify a compatible alternative. MR Industrial Accessories LLC supplies NSK and other brands to help you find the right part.
To proceed, send the complete bearing code or the bore, outer, and width dimensions via WhatsApp or email. Our team replies promptly and can suggest equivalents and help you choose. MR Industrial Accessories LLC supplies bearings, housings, and power transmission components.
