Anti-friction miniature linear guides from PM B.V. now come with a variety of cage options
When building miniature linear-motion systems, design engineers can choose between ball and crossed-roller linear guides. When applied to precision systems, most all of these linear guides have cages … [Read More...] about Anti-friction miniature linear guides from PM B.V. now come with a variety of cage options
How do miniature profiled rail guides compare to their full-size counterparts?
The basic distinction between “standard” and “miniature” profiled rail guides is the width of the guide rail: profiled rails with a width of 15 mm or less — and the carriages that fit on them — are … [Read More...] about How do miniature profiled rail guides compare to their full-size counterparts?
