HM12 HM15 Aluminum Stepper Motor Mount With Support Bearing For NEMA23
Upgrade your CNC router or 3D printer build with this single-side aluminum bracket. The integrated design combines a precision motor mount with a built-in screw support bearing. You get properly aligned shafts without stacking separate blocks, which reduces vibration and slows down component wear. Cast aluminum keeps the assembly light while holding firm during fast toolpaths or rapid print layers.
Benefits & Tips
Match the 12mm height (HM12) to standard BK12 lead screws, or choose the 15mm mount (HM15) for bulkier threaded rods.
Pick the C5 variant if you want tighter lateral control from the 7001 angular contact bearing, or select the C7 deep groove model for everyday smooth tracking.
Tighten the mounting bolts gradually to keep the flat base flush against your frame plate, which prevents micro-play during heavy loads.

Warnings & Reminders
This bracket differs from traditional steel HM12 designs and pairs specifically with BK12 and BK15 style supports rather than generic mounts. Always compare the dimension drawings against your existing screw diameter before installation. The powder coat or natural aluminum finish may shift slightly between production batches. The unit contains no high-concerned chemicals and operates safely in standard workshop environments.
