Notes: 1. For dimensions without tolerance, general tolerance applies. 2. The electromagnetic brake terminals (B1, B2) do not have polarity. 3. Only for the models with electromagnetic brake. 4. Dimensions in brackets are for the models with electromagnetic brake. 5. Use a friction coupling to fasten a load. 6. Servo motors with oil seal (HG-KR_J and HG-MR_J) have different dimensions.
