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 ...

The seals used for most bearings typically go unnoticed until something goes wrong, which often results in unexpected downtime. However, as lifecycle costs and energy savings become increasingly ...

Several applications require a through shaft which prevents from using the basic principle which is angular position measurement using variation of magnetic field amplitude induced by the displacement ...

Machines that turn, eject, cut, and spray rely on efficient, automatically reversing linear motion. Rolling-ring linear drives are commonly used in these types of applications because they eliminate ...
