FAQ: What is stick-slip?

Stick-slip, also referred to as “stiction,” is the bane of engineers and machine builders who need smooth, precise motion. Simply put, it’s the jerkiness that can plague both plain and recirculating linear bearings when they transition from standstill to motion. Here’s why stick-slip happens… When two objects slide against each other, friction works against their motion. […]

How to shrink the size of a linear actuator

Linear actuators come in a wide range of sizes, but over the past several yeas, manufacturers have been emphasizing more and more compact footprints. But no matter how small the actuator, the addition of a motor can make the overall size of the complete system too large for space-constrained applications. Some manufacturers are addressing this issue […]
