BC15Z Ball Screw Transmission Seat
A combined motor-connection and bearing-support seat that sits between the motor and the ball screw's fixed end — the flange bolts to the motor while an internal bearing pair supports and centers the screw shaft.
Description

Products Details
The main body is machined from 6063-T6 aluminum alloy, with a bearing pair (6002ZC/7002AC in Gcr15 bearing steel) pressed inside to carry the screw shaft, held in place by an S45C-steel lock nut, plate, and washer, sealed with a rubber ring to keep contamination out of the bearing. That combination is what lets this part do two jobs at once: it's the motor mounting flange and the fixed-end bearing support for the ball screw, so the motor and screw share one aligned connection point instead of being bolted together through separate brackets.
Two model variants cover different screw-end configurations: BC15ZC/AC-80 (D70/D1 90) and BC15ZC/AC-86 (D73/D2 69.6), both built around a BK15 fixed-end bearing. Mounting is a 4×M6 bolt pattern on the motor side.
We build to customer drawings under OEM/ODM. Please compare the drawing dimensions carefully against your motor and screw before ordering, and confirm samples before a bulk run.
