Profiled rail accuracy: When accuracy class doesn’t tell the whole story
You’ve chosen a profiled rail and bearing for a high-precision application — machining, cutting, or metrology, for example. The bearing (aka carriage, or runner block) has good load capacity and … [Read More...]
Under development: Linear stroke-extending technology from Ascending Power
In a recent email exchange with London-based John Hammerbeck of Ascending Power, we learned more about a novel new linear-motion extension technology from the company. The actuator steps up a short … [Read More...]
What is sub-divisional error (SDE) in linear encoders?
To determine the position of a linear axis, an encoder read head travels along a scale and "reads" changes in light (for optical encoders) or magnetic field (for magnetic types). As the read head … [Read More...]
