Zero-Max Introduces Zero Backlash Couplings

The new of ServoClass? Couplings by Zero-Max feature zero backlash and higher torsional stiffness required in modern servo motor applications with high reverse loads and precision positioning requirements. Manufactured of ROHS-compliant materials containing no banned substances, the couplings are designed with 304 stainless steel disc packs and 7075-T6 aluminum hubs and center members. According to the company's press release, their design provides high torsional stiffness with low inertia to avoid system resonance in all types of servo systems. ServoClass couplings handle system speeds up to 10,000 rpm and have a torque rating range from 4.43 in. lb. (0.5 Nm) to 530 in. lb. (60 Nm).System designers can select from 16 sizes and from combinations of inch and metric hub bore sizes to meet exacting servo drive requirements. All models and sizes feature clamp-style mounting hubs with recessed, corrosion resistant clamping bolts. Zero-Max ServoClass couplings are suitable for use in most high precision applications including packaging machines, pick and place systems, printing machinery, machine tools and most systems utilizing servomotors.
