- High quality material: Cast Iron;The bracket is made of high quality material, sturdy and durable.
- Easy Installation: The motor bracket comes with nuts and screws for easy installation and fixing of the motor.
- Bearings: use 6001 bearings.
- Advantages: The positioning hole of the integrated motor seat and the mounting hole of the bearing are processed in an integrated manner,maximize the ensure of the four-in-one motor shaft center, coupling shaft center, bearing hole shaft center, ballscrew shaft center, etc.This overcomes the disadvantage that it is difficult to coaxially install the separate motor seat and the separate bearing seat.

Nothing to dislike but could have added the socket head screws to mount the motor. It is identical to the more expensive version.

Does not follow standard BK12 size standards, and mine was full of casting flash, surface rust, and scale. Also requires an extended shaft stepper or extra long coupler. I returned mine immediately.

Bolted right up in place of the original BK12 bearing block, on the Z axis I am building, It will need a 35mm long coupler for the stepper motor. I will be buying more of these to finish out the CNC Plasma Cutter I am working on.edit to add.the next batch of 4 I ordered One came in with a lot of very sharp casting flash that needed to be filed off, another had a lot of surface rust.
