Product Details

Torque Discs

Nylon discs (resilient) - help dampen vibration and noise,Acetal discs (backlash-free) - designed for precise applications requiring zero backlash and higher torque capacity


Size 13 discs not suitable for use with clamp style couplings

Ruland Oldham Style Couplings

Paradrive™ couplings are ideal for motion control applications, especially those utilising stepper or servo motors. Their low inertia design is ideally suited to higher speed applications and where electrical isolation is also required. Small angular and axial misalignments may be accommodated.

Securing: 13mm and 19mm anodised aluminium hubs are secured to the shafts with one set screw on each end. 33mm, 35mm and 41mm hubs have 2 set screws set 90° apart
