Frequently Asked Questions
Q: What does "ZZ" mean in the flange bearing model name?
A: "ZZ" indicates that the bearing is double-shielded with metal shields on both sides. These shields help retain the pre-applied grease lubricant inside the bearing while blocking dust and debris from entering, resulting in a longer, more reliable service life in most applications.
Q: How do I choose the correct FR-series flange bearing size for my project?
A: Select the model whose inner diameter (bore) matches your shaft size, and whose outer diameter fits your housing or mounting hole. Refer to the dimensions table above — for example, FR144ZZ suits a 3.175 mm shaft, while FR1810ZZ is designed for a 7.938 mm shaft. When in doubt, measure your shaft and housing carefully before ordering.
Q: Are these JARBLUE flange bearings suitable for 3D printers and RC models?
A: Yes! The FR-series double-shielded flanged ball bearings are widely used in 3D printers, CNC routers, RC cars, drones, and hobby robotics. Their compact flange collar makes mounting straightforward, and the ZZ shields help maintain performance even in dusty workshop environments.
Q: How many bearings are included per order?
A: Each order includes 2 pieces (2 PCS) of the same bearing model/size that you select at checkout.
