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. […]

A guide to plain bearing materials in linear motion applications
One of the benefits of plain linear bearings is their simplicity. Especially when compared to recirculating bearings, plain bearings are easy to specify, install, maintain, and replace. But don’t let that simplicity fool you. Choosing the wrong bearing, or more specifically, the wrong bearing material, can result in poor performance, degradation of the bearing, or […]
Golf-club washer uses linear-motion actuators to transport wash nozzles
Soon, you could see a new station called a Riveer TourSpin Club Washer cleaning dirty irons and hybrids at a golf course or country club near you — with the help of linear-motion actuators inside. Golf games tend to improve when players use well-maintained equipment. In contrast, dirty equipment can degrade games — not to mention golf courses […]
