Bellows shaft coupling

Bellows Couplings - The two main types we supply are either Electrodeposited or Hydro-formed.

Electrodeposited bellows are manufactured by forming a mandrel to the shape of the inside of the bellows, depositing the proper thickness of spring quality metal on to the mandrel, trimming the plated mandrel to define the ends, and finally dissolving away the mandrel. This leaves behind a thin convoluted tubular shell of plated metal, which is the bellows. Servometer is the foremost manufacturer of electrodeposited nickel bellows. Bellows made of copper, silver and gold are also available.

Hydroformed bellows are normally manufactured from Stainless steel and offer exceptionally high torsional stiffness for the given outside diameter. This range predominantly uses a proven shaft hub clamp connection to ensure accurate torque transmission.

Key product advantages are

• Backlash free operation
  
• Torsionally stiff
• Maintenance free
• To suit shaft sizes from 5mm to 55mm
