OK, one more Thomson Super 8 adjustable pillow block. I swear this is the last one. Really.

Yet another adjustable pillow block for the Thomson Super 8 linear ball bushing. This one has extended flanges that allow it to be screwed down from the bearing side of the mounting plate. Mounting holes are 4mm diameter and spaced at 40mm x 25mm centers.
You will need a 6-32 screw and washer to adjust bearing preload (aka "fitment") and 4 x 6-32 screws and washers to mount the block.
