They deliver high rigidity and precision rotation, pre-lubricated for long-term use, and are widely used in CNC machinery, robotics, and automation. While robust and versatile, users should note the BK10 block requires a spacer modification to eliminate axial play for optimal performance. ## Description Support unit such as BK type bearing into the proper amount of lithium soap grease, with special sealing gasket for seal, can direct installation, use for a long time. The end support apply for electronic machinery robot, measuring instruments, medical equipment, X-Y table, factory automation equipment, etc. CNC Router\CNC grinding machine, machine tools. Product Name: BK10 + BF10 Ball Screw End Support Type: SFU1204 Material: Carbon steel Main Color: Black Weight: BK10(355g)+BF10(260g) Package Content: 1pcs BK10 ball screw end support 1pcs BF10 ball screw end support Review: Severe axial play due to missing spacer - These are shipped with a well documented flaw in the BK10 block where there is no spacer between the outer race between the two bearings, which means it is not possible to create proper preload between the bearings. 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. ## Features - 【Material】 Carbon steel,the surface blackening process - 【Widely Used】Used for CNC machine parts SFU1204 ball screw - 【Dimensions】 BK10 + BF10 ball screw end support - 【Package Include】1pcs BK10 bearing block,1pcs BF10 bearing block - 【Function】 High rigidity, high precision and stable performance of rotation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08GS32NJX | | Bearing Number | BK10, BF10 | | Bearing Type | Ball Bearing | | Best Sellers Rank | #314,632 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #53 in Linear Motion Ball Screws | | Brand Name | Befenybay | | Compatible Lubricant | Grease | | Customer Reviews | 3.4 3.4 out of 5 stars (5) | | Item Weight | 615 Grams | | Manufacturer | Befenybay | | Material Type | Carbon Steel | | UPC | 191170846601 | ## Product Details - **Bearing Number:** BK10, BF10 - **Bearing Type:** Ball Bearing - **Brand:** Befenybay - **Item Weight:** 615 Grams - **Material:** Carbon Steel ## Images ![Standard End Supports 1PCS BK10, 1PCS BF10 for CNC Machine Parts SFU1204 Ball Screw - Image 1](https://m.media-amazon.com/images/I/51lG7FCnBkL.jpg) ![Standard End Supports 1PCS BK10, 1PCS BF10 for CNC Machine Parts SFU1204 Ball Screw - Image 2](https://m.media-amazon.com/images/I/51HVntthcaL.jpg) ![Standard End Supports 1PCS BK10, 1PCS BF10 for CNC Machine Parts SFU1204 Ball Screw - Image 3](https://m.media-amazon.com/images/I/61+vK-ZO7zL.jpg) ![Standard End Supports 1PCS BK10, 1PCS BF10 for CNC Machine Parts SFU1204 Ball Screw - Image 4](https://m.media-amazon.com/images/I/51CvftP392L.jpg) ![Standard End Supports 1PCS BK10, 1PCS BF10 for CNC Machine Parts SFU1204 Ball Screw - Image 5](https://m.media-amazon.com/images/I/71b0H+lY8nL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐ Severe axial play due to missing spacer *by H***D on March 7, 2026* These are shipped with a well documented flaw in the BK10 block where there is no spacer between the outer race between the two bearings, which means it is not possible to create proper preload between the bearings.
