AC Series - Outline

Disk spring coupling:AC Series --- ACD Series / ACS Series --- Awarded the “Outstanding Performance Award” for Excellent New Technologies and Products Prize for small and medium-sized enterprises --- Awarded the “Japan Society for the Promotion of Machine Industry Chairman’s Prize” of the New JSPMI Prizes

Disk spring coupling with a brand-new slit shape
ISEL originally designed inside clamp system!
Controls installation runout to the minimum, achieving highly precise centering!

Low inertia & High rigidity
Easy installation
Cost reduction

Meets TES Standards**
** TES Standards: standards specified by Japan Machine Accessory Association (TES1401)

Usage examples

  • Connection between ball screw of feed shaft unit and servo motor on machine tools
  • Connection between drive ball screw and servo motor on precision stages
  • Connection between ball screw and servo motor on work unloading robots

Specifications

  • Outer diameter    φ19 - φ56mm
  • Shaft diameter    φ3 - φ25mm
  • Maximum torque capacity    1N·m - 25N·m


Disadvantages of conventional clamp systems
Gross deviation of shaft centering when clamped.  ---  ISEL original design inside clamp system   --- Inside clamp system that minimizes off-centering improves
bore centering accuracy by 25% or more.

Effect

Compared to the side clamp system, the inside clamp system reduces the load on peripheral devices by relieving stress to the shaft.
