1/5 82 Notes: 1. For dimensions without tolerance, general tolerance applies. The actual dimensions may be 1 mm to 3 mm larger than the dimensions indicated since the outer frame of the gear reducer is made by casting. Make allowance for the actual dimensions in the design of a machine. 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. The models with (Note 6) in the LM column of the variable dimension table have the maximum dimension of 180 mm × 180 mm in this part. 7. HG-SR_(B)G7K is also available for key shaft motor (with key). Refer to the following page for the shaft-end shape. 190 165h8 170 122 50h7 53 13 82 156 16 295.8 (66.5) 0 (44) 14 149.1 (96.9) 176
