Original Press Release:
Servo Insert Couplings Series EK2
Servo insert couplinqs up to 1.100 Nm
Taking up the challenge for greater technical demands in modern machine design and construction, R+W has developed the SERVOMAX EK2 series of elastomer Couplings.
R+W SERVOMAX couplings have an elastomer element that is press fit between two precision machined coupling halves giving it zero backlash and guaranteed concentricity. The elastomer insert is available in three different shore values 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 machines.
Sizes are available for torque capacities ranging from 10 Nm (89in. lbs) to 1100 Nm (9735 in. lbs.).
Properties:
- backlash free
- high dampening of loads or shocks
- very precise manufactured components
- three different shore values of the inserts
- low price
- high value
