In linear guides with rolling elements, balls slip against each other in opposite directions at their point contact. The high-speed point contact results in massive pressures that break down the oil film (at 3 kg/mm(super2) surface pressure) between balls.
A non-contact ball retainer eliminates point contact to reduce noise and maintenance in type SSR LM guides. The retainer positions balls evenly, improves grease retention, reduces heat generation, and extends life.
The company claims that smooth operation and less variation in rolling resistance lowers torque requirements to 1/10 that of conventional types.

Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
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.
