When do you need to consider thermal expansion in linear guide systems?
Most materials used in linear systems have a positive coefficient of linear thermal expansion — that is, when their temperature is increased, they expand in length, and when their temperature is … [Read More...]
Slide ways for precise motion control
NB Slide Ways are non-recirculating linear motion bearings used primarily in optical and measurement equipment where high precision movement is required. The SV style consists of two roller cages with … [Read More...]
Linear motion in medical applications: Linear actuators in patient lifts, beds, and tables
Moving a patient in a hospital or medical facility doesn’t always involve racing down a hallway with the patient in a wheelchair or on a gurney. Very often, a patient simply needs to be moved from a … [Read More...]
