SHR series is excellent for vibration absorption and helps to enhance effciency of application allowing higher Gain figure on the servo motors.

SHR

SD Series (Disk Coupling) SD series is excellent for absorbing misalignment by plate springs and is widely used on servo/step motors.

SDS

SDW

SDSS

SDWS

SAD Series is more stiff and durable compared to similar sized general disk couplings disk couplings (SD series) with the advanced structure in the plate spprings. We provide SAD series in small/compact sizes.

SADS

SADW

SHD Series is designed to transmit torque by adopting harder material and the advanced structure in the plate springs.

1. Advanced version of plate Spring shape

SHDS

SHDW

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.

2. Improved durability with advanced body material

SCD Series is designed to be well-concentric with higher torsional stiffness by processing inner and outer diameter simultaneously, which enables users to install the coupling in a more precise way.

SCDS

How to install

Remove dust or oil substances from the surface of both the coupling and the shaft.
Insert the shaft up to L1. Make sure the plate spring doesn’t get pressed by excessive force.
After the shaft is inserted, pre-tighten two fastening screw salternately with limited torque, in order not to make it too loose.
Place a dial gauge right on the surface which is machined with the inner diameter simultaneously (see figure), and fasten the screws alternately observing the gauge variation (run-out) is less than 0.02.
Lastly, fasten the screws with full of fastening torque by using a torque wrench.
Insert the opposite shaft while paying attention to the excessive force on the plate spring and fasten screws according to the above instruction.

※ We recommend you only use the provided screws which are
lubricated.

SJC series is the most excellent coupling for transmitting high torque and is durable for vibration/impact.

SOH

SOHMP

SOHSV

SOH series is excellent for absorption of parallet mosalignment and enables reaction force on the shaft to be reduced. It is simple for self maintenance.

SRB series is good for both angular/parallet misalignment absorption however it is relatively less-durable.
