2. When connecting the product, do not apply impact force and/or excessive thrust load on the output shaft
(use tapping hole on the output shaft for 11K to 18K).
a Since the output shaft diameter dimension tolerance of the speed drive has been
set to h6 for 200B to 7500, and m6 for 11K to 18K, set the hole tolerance of the
coupling, pulley, chain sprocket, and gear, which are to be mounted, to H7 for
200B to 7500, and F7 for 11K to 18K. Then, push the output shaft into the hole
by tapping with a wooden or plastic hammer. Pushing the shaft by hitting it hard
could result in damage to bearings and/or the inside of the speed drive.
b Chamfer the hole mouth by approximately 1 mm.
c Make clearance of 0.1 mm to 0.2 mm for the key head.
d Hold and secure the key head using a set bolt.
3.Ensure centering before connection.
■ For connection with a coupling, properly align the speed drive shaft with
the mated machine shaft.
■ For connection with pulley, chain sprocket, and gear, etc., properly make
the speed drive shaft parallel with the mated machine shaft, determine the
correct center line, and 󳞛t precisely.
Note : Make the effective diameter of the coupling, pulley, chain sprocket, and gear, etc. at least
five times the output (input) shaft diameter of the speed drive. Be careful not to allow
impact, vibration, and/or excessive thrust load from the machine to apply to the shaft ends.
(For information about allowable shaft weight, refer to the catalog).
1. Allow a suf󳞛cient margin when setting the rotating speed and torque.
■ When driving the mated machine at the maximum speed, connect the speed drive so that it also operates at the maximum rotation.
■ For machines of which torque increases at the lower speed (such as those with constant horsepower characteristics), set the maximum torque to be
within the rated torque of the speed drive.

Note : For the vertical type, be sure to set the unit vertically before adding oil. If oil
is added with the unit placed horizontally, the amount of oil will differ, and proper
lubrication management cannot be performed. If oil has been added excessively, remove
the drain plug, and drain out surplus oil to adjust the amount.
Note : Before adding oil in the vertical type of models 200B to 1500, be sure to remove the attached pressure relief plug for lubrication, which can be used to release the internal air pressure.
[ For the speed change section ]
■ Add oil up to the speci󳞛ed level of the oil gauge when the speed drive stops.
Note : Continuing operation with insuf󳞛cient oil could result in damage to internal parts.
Check the oil level every day.
■ Never mix different types of oil. Failure to follow this could result in adverse effect due to the change in oil quality.
■ Oil leakage could result in accidents. Wipe away oil spills at the time of 󳞛lling or draining.
■ For the grease lubricated system <Frame A/B/C of N(G)11 to 71>,
additional re󳞛ll is not required in the middle of the replacement interval.
When replacing oil, disassemble the unit for overhaul before lubrication.
[For the speed reduction section]
■ The plug position in the center of the speed reduction section indicates
the proper oil level. Remove the upper lubrication plug and level plug, and
󳞛ll with oil until oil 󳞜ows out of the level plug.
