Material

• Hub: Aluminium A2017 with anodised coating.
• Disc: Stainless Steel (SUS301).
• Pin: Stainless Steel (SUS303).
• Collar: Stainless Steel (SUS303).
• Cap Screw: SCM435, black oxide coating.

Performance

• Maximum Temperature: +100°C Approx.

Features

• For use with stepper motors.
• Zero backlash.
• Very good high torsional stiffness and torque properties.
• Identical clockwise & anti-clockwise rotational characteristics.
• Double stainless discs absorb angular misalignment and shaft end play (parallel misalignment not absorbed).
• Maintenance free, excellent resistance to oil and chemicals.
• Capscrews supplied. Stock cap screws may be replaced with Stainless Steel screws.
• Recommended tolerances on shaft diameters is h6 and h7.
• Minimal effect on response in static torsional stiffness caused by temperature, though operating at high temperatures may lead to misalignment due to shaft distorsion or elongation from thermal expansion.

Notes:
Adjustment of rated and maximum torque specifications for load fluctuations is not required.
Moment of inertia is based on maximum shaft bores.
