ServoClass(TM) couplings are for servomotor and precision motion-control applications and feature zero-backlash flexible metal discs and keyless clamp-type mounting hubs. The couplings offer high torsional stiffness and low inertia to avoid system resonance. The couplings' flexible design also accommodates higher torque, high speed, and high misalignment and require no maintenance. ServoClass couplings are available in six sizes in torque ranges from 8.84 to 221 inches-lb.
NASA and Boeing developed a huge, carbon composite cryogenic fuel tank for deep space missions, and started testing it last month. The 18-ft cryotank will enable heavy-lift launch vehicles to send both humans and robots into deep space.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
