The dampening characteristics of Ruland’s zero backlash jaw couplings reduce settling time and shock loads, making them suitable for the requirements of start and stop machine vision systems used in industries such as semiconductor, medical, solar, etc.

Jaw couplings are a three piece design comprised of two aluminium hubs and an elastomer element called the ‘spider’, which provides dampening of impulse loads, minimizing shock to the motor and other sensitive equipment. Available in three durometers, the spider allows the user to tailor the

jaw coupling’s performance, such as torsional stiffness, misalignment, and dampening requirements, to their application. The jaw couplings have a curved profile which press fits onto the spider assuring zero backlash operation.
