The operating characteristic of a profiled guideway is strongly dependent
on the balls running as quietly as possible. For this reason, Schneeberger, Inc.
has introduced its Monorail BM, a new linear guideway product. By reducing the
number of related transitions in ball recirculation, the design claims improved
running characteristics over competing products.
"Particular attention was focused on the run-in area as the balls transition from the unloaded to the loaded zone," explains Executive VP and Managing Director George Jaffe. "Geometrically balancing this area minimizes stroke pulsation, pitch movement, and noise."
Jaffe adds that the design permits quiet operation without relying on plastic cage elements to separate the balls. Other reliability features:
The carriage is sealed at each end with double-lip wipers, and longitudinally along the rail surfaces.
A trapezoidal rail profile enables wiper exchange without carriage removal.
Front plates incorporate a lubrication distribution system; Lubricant may be applied in any of four locations--front, either side, or top.
Produced in six sizes--15, 20, 25, 30, 35, 45--and four carriage types, the new Ball Monorail is applicable to general automation, pick-and-place, semiconductor wafer handling, and machine tools. As with Schneeberger's well-known MR roller guideway, the Monorail BM is available in four accuracy grades and three preload classes.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
