All stainless steel design (1.4301) accommodates 4- to 20-mm diameter shafts.
Inner and outer split sleeves with opposing tapers form this friction-based system. A clamping nut climbs tapered threads of the inner sleeve to grip the shaft.
At the same time, tightening torque pushes the outer sleeve up the inner sleeve's inclined surface, distributing clamping force in the axial direction. Benefits include 360-degree clamping, no screws or keyways, and quick assembly/disassembly.

The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
