In a rolling ring linear drive, three or four rolling ring bearings are housed inside the nut. When the nut is placed on a smooth shaft, and the shaft is rotated, compression is generated against the bearings'' inner races. This causes the bearings to roll along the length of the shaft. A payload attached to the nut is thereby moved linearly.
2001-2-16 · Bearings for shafts that oscillate axially as well as rotate offer a special challenge to rolling bearing designers. Such shafts exist in many branches of industry and include inking and damping rolls in printing machines, jigging rolls in textile machinery, and rolls in belt grinders and leather treatment equipment, to name just a few.

Rotating unions (also known as rotary joints, rotary couplings, and rotary swivels) are precision mechanical devices used to transfer fluid from a stationary source, such as a supply pipe, into a rotating piece of machinery. Rotating Unions are used in numerous manufacturing processes to cool, heat, or transfer fluid (pneumatic or hydraulic) power.
