Let’s break down the different types of linear bearings you’ve mentioned for 3D printer parts rods:
LMK6UU: This is a square flange linear bearing with a guide width or diameter of 6mm. It’s designed to provide smooth linear motion along a shaft or rod in CNC machines and 3D printers. The square flange ensures stability and easy mounting. You can find this type of bearing on platforms like AliExpress and Amazon UK.
LMF8UU: This one is a round flange linear bearing with a guide width or diameter of 8mm. Similar to the LMK6UU, it’s commonly used for linear motion applications in machinery and 3D printers. The round flange design allows for secure attachment to the rod or shaft. You can also find this type on AliExpress.
LMH8UU: Unlike the previous two, the LMH8UU is an oval flange linear bearing. It has a guide width or diameter of 8mm. The oval flange shape provides flexibility in mounting orientations. These bearings are suitable for various applications, including 3D printers. You can find them on AliExpress.
