SUNG-IL - Coupling
SCJ Series


Product Features & Application :
-
SCJ series is excellent for absorbing both angular/parallel misalignment through middle pin/bushing structure and minimizes reaction force on the shaft. (This coupling combines strong features of SOH series coupling and universal joint.)
-
This series structurally doesn’t absorb end-play.
SFC Series

Product Features & Application :
-
SFC series is flexible with Urethane material and is especially excellent for absorbing misalignment to a greater extent.
-
The middle Urethane structure absorbs external impacts and absorbs vibration.
SHD Series


Advanced version of Plate Spring shape : Sung-il developed the improved version of plate spring with doubled assembly holes to disperse stress concentration, and it enhances both strength and stiffness to the higher extent.
SHR Series


Product Features & Application :
-
Great for Anti-vibration & increasing gain on Servo motor → High Productivity
SJC Series


Product Features & Application :
-
Great for Anti-vibration & increasing gain on Servo motor → High Productivity
SOH Series


Product Features & Application :
-
SOH series transmits motion through the middle spacer and is particularly excellent for absorption of parallel misalignment.
-
It has a simple structure for easier self-maintenance.
-
It enables reaction force on the shaft to be reduced by moving the spacer even though there is parallel misalignment.
-
Sung-il Machinery provides various spacer types which are allowed to be used in special circumstances.
SRB Series


Product Features & Application :
-
SRB series is one-piece metal coupling with no backlash and absorbs misalignment through its slit structures.
-
SRB series is made of ultra high strength aluminum alloy material (AL-7075-T6) in order to enhance its durability.
SRG Series

Product Features & Application :
-
SRG Series is one-piece metal coupling with no backlash and it doesn’t allow any loss of motion while transmitting.
-
Because this series doesn’t absorb misalignment, the allocation of shafts should be set-up in line accurately without any misalignment.
