Notes: 1. For dimensions without tolerance, general tolerance applies. 2. The electromagnetic brake terminals 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. For HG-SR series, dimensions are the same regardless of whether or not oil seal is installed.
