Frequently Asked Questions

Q: What sizes are included in this 4-pack of axial thrust bearings?

A: This listing offers multiple size options including F3-8, F4-9, F5-10, F6-12, F7-15, and F8-16M miniature planar axial ball thrust bearings. You receive 4 pieces per pack in your chosen size. Please select the correct model number for your application before ordering.

Q: Are these thrust bearings compatible with the V-Core 3 3D printer?

A: Yes! These miniature planar axial ball thrust bearings are specifically noted for compatibility with the V-Core 3 and similar precision 3D printer platforms. Their compact, low-profile design makes them well-suited for the tight tolerances found in modern CoreXY and other motion systems.

Q: What material are these bearings made from?

A: These bearings are manufactured from high-grade bearing steel, which provides excellent hardness, wear resistance, and long-lasting performance under continuous axial load conditions — ideal for 3D printers, CNC machines, and other precision equipment.

Q: What is the difference between an axial thrust bearing and a standard radial bearing?

A: An axial (thrust) bearing is designed to handle loads applied parallel to the shaft axis, while a radial bearing handles loads perpendicular to the shaft. The planar/flat design of these F-series thrust bearings makes them perfect for applications where components press against each other along the axis of rotation, such as lead screw assemblies in 3D printers.
