Description
NSK F 687 ZZ1 belongs to deep groove ball bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for F 687 ZZ1 and any equivalents.
The NSK F ZZ series is a flanged deep groove ball bearing supplied with metal shields on both sides. Because the outer ring carries an integral flange, the bearing can be seated directly against a flat surface instead of a machined shouldered housing. This suits layouts where axial room is tight and the mounting has to stay simple and secure.
Reading the code helps you order the right size. The letter F tells you the bearing has a flange; the number that follows sets the bore and the outer dimensions; the ZZ or ZZ1 suffix means shields are fitted on both sides. Two examples from the same family are F 607 ZZ1 and F 625 ZZ1, where only the central number changes to reflect a different bore and outside diameter.
Typical duty covers fans, small electric motors, pumps, transmission equipment, machine tools and household appliances. You will also find this style on packaging lines, refrigeration units, ventilation systems and agricultural machinery. The flange simplifies fastening to chassis and plates, while the shielded design copes with moderate dust and dirt.
When selecting, work from the shaft diameter, the housing dimensions and the expected load. The flange face needs a clean, flat seat, and alignment should be checked so the bearing is not loaded sideways. Shields are greased for life at the factory, so no relubrication is normally required; in damp or heavily contaminated areas, a bearing with a more protective seal is the better choice.
Interchange is possible with other brands that use the same dimensional nomenclature. Send the part number you currently run and we will identify the equivalent. What matters is that bore, outer diameter, width and flange mounting style all match, and a flangeless bearing should not be substituted where the original mounting depends on a flange.
To get a quote, message the complete part number by WhatsApp or email. If the number is not at hand, give us the shaft and housing dimensions and we will come back with the correct reference. We supply the NSK line and reply promptly, and we can also suggest equivalents or help you choose.

Frequently asked questions
- What does the ZZ suffix mean on an NSK bearing?
- It means metal shields are fitted on both sides. They keep dust out and hold the lubricant in place. Because the shield does not contact the rolling elements, the bearing remains suitable for higher speeds and moderately dirty surroundings.
- How do I pick the right flanged bearing?
- Start with the shaft diameter, the outer diameter and the width, then confirm the flange matches your housing. If you still have the original part number, send it over and we will quote the equivalent reference. We can also identify the bearing from its dimensions.
- Can NSK F ZZ series bearings be swapped with other brands?
- Yes, provided the dimensions and the flange type are the same. Each manufacturer may use its own nomenclature, but the standardized dimensions allow interchange. Tell us the part number of the brand you use and we will confirm the equivalent.
