Look closely and you will see that this patented family of stages greatly surpasses the performance of most, apparently similar, stages. The design and method of manufacture provides many benefits. First, there are far fewer parts than expected. The stages consist of a top plate and a bottom plate only. There are no intermediate plates and no bearing adapters to add to the tolerance build-up. Linear bearing ways are machined directly into the steel plates and honed to provide the highest possible precision. Second, the ball bearings are contacted by an extended curved surface which provides greater load capacity and higher precision than crossed-roller bearings.
