Taking up the challenge for greater technical demands in modern machine design and construction, R+W has developed the SERVOMAX series of elastomer couplings.
R+W SERVOMAX couplings have an elastomer element that is press fit between two precision machined coupling halves resulting in zero backlash and guaranteed concentricity. The elastomer insert is available in three different shore values, 80 Shore A (yellow), 98 Shore A (red) and 64 shore D (green), allowing the customer to choose how great of a dampening effect is required for the application. The elastomer insert also electrically insulates the two coupling halves.
SERVOMAX couplings are mainly used in applications requiring precise motion and a high degree of dampening like CNC milling and turning operations.
