Oldham Coupling

SOH Series Classification
  • 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.

Center-Through Spacer Option is available
  • If the shaft has to be inserted deeper than L1 value, we can provide appropriate center-through sleeves.
  • Please indicate additional mark (TH) next to the part no. Please refer to “HOW TO ORDER” for more details.
  • Center-Through (TH) is standard for the following models, SOH-6,8,10,12, SOHM-12C, SOH-70C, 90C, 120C and all sizes of SOHMP & SOHV series.
  • The standard color of spacer for SOH-6, 8, 10, 12 is white, but the material is the identical Polyacetal(POM).
