An Overview of Hydraulic Nuts

Hydraulic nuts are capable of producing high bolt loads in small, compact spaces.   They are designed to replace existing torqued hardware and remain part of the bolted joint after installation. All hydraulic bolt tensioners, including hydraulic nuts, produce purely axial loads that are independent of stud twist and frictional effects that lead to unpredictable bolt loads when using conventional torque methods.   Using hydraulic nuts allows for more accurate preload control and improved repeatability from stud…

Stick-Slip in Long Shaft Systems

Stick-slip is a phenomenon that occurs in mechanical systems where resistance to motion is due mostly to coulomb type friction. Coulomb friction is characterized by resistance that is one value when contacting surfaces are stationary relative to one another and lower when they are sliding. The threshold between static and dynamic friction forms a discontinuity which leads to a sharp change in resistance across a narrow change in relative speed. This effect can lead to…
