A well-optimized linear unit offers a versatile, compact motion solution that can reliably serve an application for years.

Whatever, we don’t judge, but the build requires a short-throw linear drive mechanism that can be back-driven, specs that argue for a ball screw. [Andy] goes through the challenges of building ...

The new drylin WWP linear guide from igus features a PTFE-free locking carriage. Engineered from lubrication-free, ...

Ball screws are the most deployed technology for converting rotary motion to linear motion, but they are subject to many factors that can result in premature failure, including misalignment ...

We were most interested in the six custom-made linear actuators, though. Aluminum extrusions form the frame holding BLDC motor, and guide the nut of a long ball screw. There are a bunch of 3D ...
