Rotary motion is simple movement of motion in a circle. It is the starting point for many mechanisms. Rotary motion is measured in either angular velocity or in revolutions per minute. The direction of turn is also part of the measurement of rotary motion.
Same way a non rotary compressor works
how does a rotatory pump work

pretty good explanation here...http://auto.howstuffworks.com/rotary-engine.htm
A rotary seal would be used in mill work. You will need trainign in order to operate a rotary seal.
The main types of movement for mechanisms are rotary, linear, reciprocating, and oscillating. Rotary movement involves rotating around an axis, linear movement involves moving in a straight line, reciprocating movement involves back-and-forth motion, and oscillating movement involves swinging or vibrating in a regular repeating pattern.
It is the reciprocating motion of the pistons that is changed into rotary motion by the cam axle.
Rotary motion in one component can be transferred to another component in the same structure using mechanisms such as gears, belts, chains, or direct coupling. These mechanisms ensure that the rotary motion of one component is transmitted effectively to the other component without loss of energy or speed. The selection of the transmission method depends on factors such as the desired speed, torque, and efficiency of the overall system.
The four types of motion mechanisms are rotary motion, linear motion, oscillating motion, and reciprocating motion. Rotary motion involves circular movement, linear motion involves movement in a straight line, oscillating motion involves back and forth movement, and reciprocating motion involves alternating movement in opposite directions.
Linear motion can be converted to rotary motion using mechanisms like gears, pulleys, or cams. For example, a rotating gear can engage with another gear to convert linear motion into rotary motion. This conversion allows for transferring power from one direction to another efficiently.
Household objects such as scissors, retractable pens, and folding chairs use linkage mechanisms. These mechanisms help in converting one type of motion into another, such as translating rotary motion to linear motion or vice versa, to perform specific functions efficiently.
