135 1/33 1/45 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 (B1, B2) do not have polarity. 3. Only for the models with electromagnetic brake. 60 115h7 120 84 32H7 13 13 75 157.6 M8 12 11

4. Dimensions in brackets are for the models with electromagnetic brake. 5. Lead out the power cable in opposite direction of the motor shaft. 6. The values in brackets represent the dimensions of flange.
