8mm Self aligning Igus bearing

thingiverse

This bearing can replace many bearings used for linear or rotational movement, making it a versatile option. Suitable for 8mm stainless steel rods, which are often supplied with affordable Chinese 3D printer kits. Replace the LM ball bearings before they become marred by excessive use :). The ball is crafted using Igus filament, while the housing can be made from PLA, ABS, or any other suitable material. To achieve a smooth exterior, the ball must be sanded with abrasive cloth or a file. Mounting it on an 8mm bolt and securing it with a drill press or regular drill makes the process relatively easy. For a precise fit, use an 8mm reamer to finish the interior of the housing; this step is crucial for proper operation. Additionally, the housing interior requires a smooth finish, which can be achieved by using a small abrasive ball (about 6 to 12). To install the ball, align it sidewise with the cuts in the housing, apply gentle force, and then rotate it into place. The mounting axis, surface, and distance between mounting holes are identical to those of the SC8U series, making it an ideal replacement. The IGUS ball is designed with a larger theoretical ID to compensate for the Igus filament's behavior, resulting in a smaller ID. A second option has a closer ID of 8mm yet still offers sufficient "meat" for adjustment using a reamer. I have also added a new ball that is better suited for linear movements.
