Description
NSK FR 188 ZZ 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 FR 188 ZZ and any equivalents.
The NSK FR ZZ is a single-row deep groove ball bearing with a flanged outer ring, allowing it to sit directly in sheet metal or light housings without a deep machined seat. The flange centers and holds the bearing, while ZZ metal shields on both sides keep out light contaminants. It suits compact assemblies where axial space is tight and maintenance needs to stay simple.
Reading the code helps you order the right part. FR marks the flanged outer ring; the following number sets the size within the series; ZZ means metal shields on both sides. So FR 0 ZZ, FR 1 ZZ, FR 1-4 ZZ, FR 1-5 ZZ, FR 2 ZZ, FR 2-5 ZZ, FR 3 ZZ and FR 6 ZZ are all the same execution, only different sizes. To order, just give the full part number.
These bearings turn up in folded sheet metal housings and light supports: fans and extractors, small electric motors, appliances, refrigeration equipment, office machines, portable tools and low-power transmission mechanisms. Maintenance teams use them to replace a specific part without touching the whole assembly. The flange simplifies mounting and cuts housing machining.
When selecting, look at load type, speed and the surrounding environment. ZZ shielding handles moderate dust and moisture; for liquids or aggressive dirt, consider an elastomer seal version. Make sure the flange sits clean and square, and that the shaft enters without impact—forced mounting damages the raceways. The bearing is pre-lubricated, so avoid solvent washing and keep the assembly aligned during replacement.
Equivalences for flanged bearings are set by designation and main dimensions: bore, outer diameter, width and flange geometry. Brands use different prefixes and suffixes, but the same size can be interchanged if those dimensions and the sealing type match. If you have an unidentified part or another brand's code, we can point you to the compatible alternative and quote it.

Frequently asked questions
- What does the ZZ suffix mean on an FR bearing?
- ZZ indicates metal shields on both sides. This sealing retains lubricant and slows the entry of dust or light dirt, with less friction than an elastomer seal.
- How do I request a quote for an NSK FR bearing?
- Send the complete part number by WhatsApp, for example FR 1 ZZ or FR 2-5 ZZ, along with the quantity. We will quote it promptly. If you are unsure about the designation, also send a photo or the housing measurements.
- Can I replace an FR bearing from another brand with an NSK one?
- Yes, if the bore diameter, outer diameter, width and flange geometry match. Brands use different prefixes and suffixes, but size and sealing type define interchangeability. If you provide another brand's part number, we will indicate the equivalent.
