140 14 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. 4. Dimensions in brackets are for the models with electromagnetic brake. 5. Use a friction coupling to fasten a load. 115h7 120 98 40h6 11.5 15 169.6 44.5 60 105.5
