In this case the issue is worse because there is about 1mm of axial play left when the two bearings are supposed to be constrained axially, even with the clamping flange tightened all the way down.To use these at all you will need to manufacture a simple spacer. I have no idea how these could be manufactured and sold with such a glaring mistake.The BF10 has no shoulder and the bearing is simply press fit into the housing.Both have simple deep groove 6001 bearings which is expected at this price. I was surprised that both parts are made from steel and not aluminum. ### ⭐⭐⭐⭐⭐ Performed as expected *by on Reviewed in the United States 30 April 2022* Modified this product to crush soda cans. The ball screw is able to handle the 60 pounds of force that the stepper motor put's on it to crush the soda cans. Well designed product. ### ⭐⭐⭐⭐⭐ Befenybay Ball Screw *by on Reviewed in the United States 3 February 2024* Good Product and fast delivery. ## Frequently Bought Together - Befenybay Standard End Supports 1PCS BK10, 1PCS BF10 for CNC Machine Parts SFU1204 Ball Screw - 23.62 inch / 600mm Ball Screw RM1204 SFU1204 (End Processing) with Metal Ball Screw Nut and BK10/BF10 End Supports for DIY CNC Machine and 3D Printer - Befenybay Ball Screw SFU1204（Diameter 12mm Pitch 4mm）Length 300mm with Metal Nut for CNC Machine Parts --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/600110502-standard-end-supports-1pcs-bk10-1pcs-bf10-for-cnc-machine](https://www.desertcart.pt/products/600110502-standard-end-supports-1pcs-bk10-1pcs-bf10-for-cnc-machine) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-29*
