Original hydraulic system connects with a single bolt
Our original hydraulic system connects with a single bolt. The shaft and hub are coupled by friction without use of keys, so the shortcomings and difficulties of key couplings are solved all at once. Its construction is simple, mounting and removal are easy, and it can accurately position and index. This greatly reduces work from the design stage to assembly, calibration, and maintenance. ,It can be mounted using a single bolt, and many models are available, including the ETP-T, which meets a concentricity of 0.006 mm.

Applications :
Machine tools/Pumps/Molding machines/Printing machines/Palletizing robots/Tools and jigs
Printing Presses
Product Models Used : SFC + ETPETP bushing is used to fix the feed roll. The roll and the shaft can be fixed easily and accurately, and the size in the direction of the shaft can be reduced.

Applications for Slitter Knife Holders![]() This is a hydraulic slitter knife holder. This holder is used to position the rotating knife to cut tin, iron, aluminum plates, or paper sheet in any position. Petitioning in the shaft direction can be performed arbitrarily with 1 bolt. For the angular deflection caused by detachment and attachment, a micron meter(μm) level repeatable accuracy can be maintained. |
Applications for Models that are Integrated with the Gear![]() Including the gear as part of the machine structure ensures an extremely precise level of bore concentricity and makes it easier to position parts along the shaft and engagement directions. |
Accommodating Different Sleeve Lengths to Meet Specific Requirements![]() The length of the sleeve can be made shorter than that on standard models as needed to meet specific requirements for accommodating parts with thin counter mounting hubs. |
Applications for Retaining Jigs![]() Placing the retaining jig on a workstand or similar stand to use as a parts holder during assembly and machining work enables work to be performed more stably. Use of a retaining jig also allows the part retaining position to be reproduced at an extremely high level. |
Q : Please let me know about the durability of the ETP bushings.
A : If the rated torque is cyclically applied to the ETP bushing, it can withstand about 500,000 cycles in terms of fatigue life. If 75% of the rated torque is applied, it can withstand an unlimited number of cycles in terms of fatigue life.
Q : Can I use the ETP bushings for the shaft and hub with keyways in them?
A : You can use the ETP bushing by completely filling the keyway with epoxy putty for metals and then shaping it. If you use the device with keyways on the shaft and hub, the sleeve may be deformed and the device may become unable to be detached and attached again.
