Miniature coupling is ideal for micropumps
Compact coupling is composed of a flexible beam-cut polyamide element clamped to shafting with stainless-steel hubs and set screws.
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.
An integrated ball-detent torque-limiting element has also been added to disengage the drive and driven elements within milliseconds in the event of a machine jam or collision.
The torque limiter is a backlash free design and is available in versions that will freewheel until manually reset, or that will automatically reengage when the transmitted torque falls back to an acceptable level.
Servomax safety couplings are mainly used in applications requiring precise motion and a high degree of dampening like CNC milling and turning machines, and are ideal for metal working machinery also because of its protection from jams and overtravel.
Sizes are available for a wide variety of torque capacities and shaft sizes.
