Metal disc couplings SERVOFLEX

Hřídelové spojky SERVOFLEX
The main advantage of metal disc couplings is their high stiffness and low inertia. They are made of durable aluminium alloy (SFC) or of high-quality steel (SFS, SFH, SFM, SFF, SFD, SFF-N).
Metal disc couplings are developed for high-speed and high-precision positioning and ultra-precise control of servomotors. While achieving high stiffness, high torque, low inertia, and high response speed, these couplings are also flexible in the torsional direction, in the uneven directions, and in the shaft direction, and are totally free from backlash 

Single or double element type

SERVOFLEX disc shaft couplings are made either as single or double-element types.
The advantage of the single-element design is higher stiffness, smaller installation size and a lower price.
The advantage of the double-element design is higher flexibility suitable for mounting with higher misalignment and easier assembly.
Users can choose the type that is preferable to their storage options, depending on whether they need misalignment or require higher rigidity. For example, machine tool manufacturers usually choose a simple design because their products are very accurate and therefore do not need to solve misalignment problems, but high rigidity is very important to them.

Flexible element – metal membrane

The metal membrane is the most important part of the SERVOFLEX coupling. It is made of the most durable material.
The shape of the membrane is also very important, affecting the stress distribution in the membrane, which significantly affects its life and functionality. 

Servoflex – use for machine tools production

Machine tools producers choose SERVOFLEX couplings because of their high stiffness and accuracy. MIKI PULLEY is the dominant supplier of shaft couplings to Japanese machine tool producers.
