An Overview of Some Linear Motion Products/Systems

Linear motion is the most fundamental kind of motion. It is based on the principle that objects that are not subjected to external forces will continue to progress in a straight line without a break. Linear motion is basically the movement along a line or length of area. Linear motion may vary; it could be uniform at a constant speed, or non-uniform with fluctuations in speed. Linear motion is sometimes also referred to as rectilinear motion.

Today, linear motion technology is being used in various industries for the purpose of automation. Some linear motion products/systems are briefly described below to provide you an idea of the use of linear motion technology.

CAM Follower

A cam follower system is a system or mechanism that makes use of cam and follower to create a certain motion. It is also called a track follower. Cam is basically a flat piece of metal that has a shape or a profile machined onto it. This cam is attached to a shaft which enables it to be turned by exerting a turning force on the shaft. As the cam starts to rotate, it is the profile or shape of the cam that makes the follower to move in a certain way. The movement of the follower, in turn, is transferred to another part of the system.

Actuators

Actuators are very useful devices that are widely used in the modern industries. They convert linear motion into automatic action. Actuators come in different shapes and styles to meet different motion requirements in different industries. There are basically three types of linear actuators, viz. basic, compact, and rodless cylinder type. Each type is suitable for a certain kind of motion. Basic and compact types are best used in individual and dual actions, while rodless types are best suited for long stroke applications.

Roller and Ball Slides

Roller slides, which are also referred as crossed roller slides, are non-motor operated linear slides that offer high precision linear movement for the equipment powered either by inertia or by hand. The roller slides, composed of roller type bearings, provide heavy load capabilities and more precise maneuver. Roller slides are primarily used in the manufacturing industry. Ball slides or ball bearing slides are the most common type of linear slides. These slides offer a smooth and precise movement along a guide rail. The applications of ball slides mainly include robotic assembly and high-end appliances.

Linear motion systems have a crucial role to play not only in the modern industry, but our day to day lives. Many equipment that we use in our day to day lives are based on the linear motion technology.
