¢º »ç¿ë¿¹ Applications
[For machine tools]
Used to couple the servomotor with the ball screw of NC lathes or machining centers, and the motor shaft with the main shaft. Used to couple the units of rotary press machines. Shear-pin type couplings are used to protect against
[For rotary press machines]
Used to couple the units of rotary press machines. Shear-pin type couplings are used to protect against overload.
[For pumps]
The spacer-type coupling is necessary for easy maintenance. For use in heated water and oil pumps, types with larger misalignment absorption capacity are more abvantageous.
[For cooling towers]
The motor is isolated from the humid, corrosive atmosphere and is coupled with the gear box below the fan via a floating shaft coupling.

Notes:
1. Do not use floating shaft coupling with long, overhanging shafts. Please consult us wheh D dimension exceeds 6,000mm.
2. Rotation speed limits shown in the table refer to couplins using our standard pipe For rotation slpeeds over this limist, please consult us.
