MOTION CONTROL: Servometer®/PMG LLC precision, electrodeposited, nickel alloy, bellows-type, flexible shaft couplings provide torque capabilities from 2 oz-inch (1.4 Ncm) to 20 lb-ft (27 Nm), for shaft sizes ranging from .090 to 1 inch. Because of their flexibility, the low torque couplings can handle angular misalignment up to 31 degrees or parallel misalignments (shafts parallel but offset) up to .076 inch. In general, as flexibility increases, torque capacity decreases. For attachment to shafts, standard set screw hub, split hub with clamping collar or integral clamp hub styles are available. Unique characteristics of Servometer bellows couplings include zero backlash; vibration damping capability; zero cyclic speed variation during 360-degree rotation; very low elastic windup, due to torsional rigidity; and low side thrust on bearings because of lateral flexibility. Bellows couplings are for use in critical applications such as resolvers, encoders, servos, motion control devices and computers.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
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.
