Frequently Asked Questions
Q: What 3D printer models are F623ZZ flange ball bearings compatible with?
A: F623ZZ flange bearings are widely used in VORON, Delta, Rostock, and Kossel Mini 3D printers as pulley guide wheels. They fit any build requiring a 3 mm bore, 10 mm outer diameter, and 4 mm height bearing with a flange rim for axial alignment.
Q: What does the "ZZ" designation mean in F623ZZ bearings?
A: The "ZZ" indicates the bearing is double-shielded with metal shields on both sides. This keeps lubricant in and dust or debris out, extending the bearing's service life — especially important in 3D printer environments where fine particulates are common.
Q: What material are these F623ZZ bearings made from?
A: These bearings are manufactured from GCR15 high-carbon chromium bearing steel, a standard industrial grade known for its hardness, wear resistance, and dimensional stability — ensuring accurate, long-lasting performance in precision motion applications.
Q: How many bearings will I receive per order?
A: The quantity depends on the option selected: Option No. 1 includes 10 pcs, Option No. 2 includes 6 pcs, and Option No. 3 includes 4 pcs of F623ZZ flange ball bearings.
