BXW [R] Model
![三木プーリの無励磁作動形ブレーキ BXW[R]タイプ 製品画像（無励磁作動 保持用・復帰機構対応・産業用電磁ブレーキ）](/media/cb_of_hld_xwr_0l.jpg)
This R-type holding brake shares virtually the same basic design as the BXW model, which offers three load torque variations with identical dimensions. Among non-excited holding brakes, this model is specifically designed to match the specifications and dimensions of small servo motors with 40, 60, and 80-degree flanges.
