One of the greatest advantages of designing plastic parts is the vast number of assembly options a designer can apply to his or her design. The most common among these options is the use of screws.

It’s easy to cut bolts and small machine screws to length. On the other hand, there isn’t any job so small or simple that it can’t be done wrong, and this is a classic example. Get it right, and you ...

Roller screws convert rotary motion into linear motion just like acme and ballscrews. Comparably sized roller screws, however, have better efficiency than acme screws and can carry larger loads than ...

Planet Earth is spinning at a rate of 0.0007 rpm. Easy to calculate: One revolution per day, divided by 24 to get revs/hr and then by 60 to get revs/min = rpm. As for linear speed, it depends on where ...

Knowing the details of a linear-motion application increases the odds of choosing the right ball screw. The more thrust an application requires, the larger the diameter screw will be needed. That’s ...

Translating rotary motion to linear motion is a basic part of mechatronic design. Take a look at the nearest 3D-printer or CNC router — at least the Cartesian variety — and you’ll see some mechanism ...

Even if you aren't the handiest person in the world, you've probably encountered a stripped screw or two in your time. They are a common enemy of the home do-it-yourselfer and can throw a wrench in ...
