A ROTATING shaft can exhibit torsional vibration when, because the dynamic coefficient of friction is less than the static value, the frictional force at the bearings supporting the shaft decreases as ...

Bores are sealed with ‘O’ rings' sited in grooves, (figure 1). The ‘O’ rings' are usually of toroidal shape (i.e. circular cross section) and are regulated by BS 1806 and BS 4518. Figure 1. ‘O’ Ring ...

Rotary actuators produce oscillating power by rotating an output shaft through a fixed arc. They are compact, simple, and efficient. They produce high instantaneous torque in either direction and ...

Noncontact magnetic rotary encoders are hard to beat when it comes to measuring rotary motion in machinery, as they are relatively small, strong, and inexpensive devices compared to traditional ...
