Description
NSK FR 168 BZZ 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 168 BZZ and any equivalents.
The NSK FR series covers deep groove ball bearings built to handle radial and axial forces in either direction. Their compact envelope and high-speed capability suit tight spaces where quiet, steady running matters. MR Industrial Accessories LLC supplies this series to maintenance and purchasing teams across the United States and Latin America.
Reading the code helps you order the right variant. Take FR 168 BZZ: FR marks the series, the number gives the size, B belongs to the configuration of that variant, and ZZ tells you there are two metal shields, one per side. Knowing how the suffixes work makes it easier to match a bearing to the environment it will run in.
You will find these bearings in electric motors, pumps, fans, machine tools and transmission equipment, as well as in food, textile, chemical and metallurgical plants where dependable operation and infrequent maintenance are priorities. Precision instruments and medical devices also use them.
Sealing choice is a key part of selection. ZZ metal shields keep dust and dirt out, though they hold lubricant less tightly than rubber seals. Also look at lubrication, internal clearance and shaft alignment at assembly. Careful fitting and correct lubrication help the bearing run longer and with less vibration.
Interchange is possible between deep groove ball bearings from different makers when the main dimensions and protection type line up, but tolerances and load capacity still need checking. If you have a code from another brand, our team can point you to the equivalent in the NSK range or another brand we carry.
To get a quote, send the complete code or the dimensions through WhatsApp or email. We reply promptly and can suggest equivalents or help you choose. Our own manufacturing covers split plummer block housings, roller chains and sheaves.

Frequently asked questions
- What does the BZZ suffix mean in FR 168 BZZ?
- The ZZ portion means the bearing carries two metal shields, one on each side. The B is part of the designation for that particular variant. These shields block dust and particles, but they do not seal as tightly as rubber seals.
- Is this bearing suitable for high speeds?
- Yes, FR series deep groove ball bearings are made to run at high speeds. Their precision build and low weight keep friction and heat down. Check the load and lubrication conditions for your application to confirm performance.
- Can I replace a bearing from another brand with this NSK one?
- Often yes, provided the main dimensions and protection type match. We advise verifying tolerances and load capacity. Send us the original part code and we will identify the equivalent we supply.
