BACKLASH DISK COUPLING
DISC COUPLING is a uni-body type which provides a
extensive twisting hardness and prominent mobility.
Disc coupling is a high precision coupling one can expect the
life-time longevity.
Disc Coupling is able to rotate with
high speed to a single direction or bidirectionally and is used
often mainly in high-precision measuring equipments, high speed
movement control systems, critical loads, dynameters
precision
encoders and etc.
Feature
- Designed for enduring high twisting
hardness
- No influence from backlash and providing long
life
- Accepting parallel, angular, shaft in-between
-
Single-and Double-Stage types
- Uni-body metal
structure
- Less inertia
爽
- Servo motor, Stepping motor,
Precision motor
- High precision encoder, Dynamo drive
- High speed, high precision position control sytem
centrifugal separtor
- Copy machine, information &
Communication,
