BK15 BF15 Bearing End Blocks, for Ballscrew 20mm Linear Motion CNC Ball Screw SFU2004 SFU2005 SFU2010, with Angular Contact Bearing

BK15 BF15 End Blocks for 20mm CNC Ball Screws SFU2004/2005/2010
✔️ Includes BK15 fixed + BF15 floated end blocks, locknuts, circlips

The BK15 BF15 bearing end blocks are designed for 20mm ball screws used in CNC machines, 3D printers, and other precision motion setups. This kit includes both fixed BK15 and floated BF15 blocks with necessary hardware for quick, reliable mounting. The angular contact bearing in the BK15 provides higher axial rigidity and longer service life than standard blocks. Made from carbon steel with high precision, these blocks are built to endure demanding environments and maintain alignment over time. Compatible with SFU2004, SFU2005, and SFU2010 ball screws and common CNC components like couplers and brackets. Pack includes: 1 BK15, 1 BF15, 1 locknut, and 1 circlip for a complete setup.
