Slide Rails are designed to provide free motion in one dimension. Utilizing linear motion bearings, Slide Rails provide low-friction linear movement. Most Slide Rails use ball bearings, while others find benefits in using dovetail bearings or linear roller bearings.

Ball bearing slides are the most commonly used type of Slide Rails. Ball bearing Slide Rails, offer smooth precision along a single-axis linear design, assisted by housed ball bearings of the Slide Rails block, with self lubrication properties that increase reliability.

Slide Rails can be constructed from materials such as aluminum, hardened cold rolled steel and galvanized steel. Slide Rails consist of two linear rows of ball bearings contained by four rods which are located on different sides of the bearing block. The Slide Rails ball bearings and rods provide support to the carriage for smooth linear movement along the ball bearings. Slide Rails bearing block low-friction linear movement can be powered by either a drive mechanism, inertia or by hand. Slide Rails can be limited to a lower load capacity for their size compared to other Slide Rails because the balls are less resistant to wear and abrasions.

The purpose for Slide Rails is to position objects as accurately as possible along a single axis. The two main parts to Slide Rails include a rail and a carriage. The rail of the Slide Rails is the stationary base in which the carriage slides along through rollers or bearings in order to minimize rolling friction and maximize efficiency. There are different types of Slide Rails fit for different industries and applications. For example, ball-bearing linear slides are typical for lighter duty and self-lubricating applications while dovetail Slide Rails are used for heavier loads.

The Slide Rails are ideal for a wide variety of industrial type applications. These Slide Rails applications include CNC, laser machining, drilling machines, grinding machines, material handling equipment, industrial robots, medical and optical equipment and many more. Slide Rails provide applications a smooth, fast and accurate positioning due to low friction. Slide Rails also provide the benefits of project cost reduction. The low coefficient of friction that Slide Rails offer allows users to downsize to smaller drives and motors.

Slide Rails can be configured in many different ways. The ranges of options Slide Rails have allow users to match the right Slide Rails to their application. Changes to these options makes up different types of Slide Rails. Some options that can be changed include preload, accuracy, and lubrication.

Some applications do not call for Slide Rails to be preloaded, even though preload is preferred because of the elimination of internal clearance and the increase of rigidity. The purpose of preload is mainly to reduce elastic deformation in Slide Rails caused by the load. The reduction of elastic deformation increases the rigidity of Slide Rails by applying stress in advance to the contact area between the raceways and rolling elements. Slide Rails usually have the options of standard, light, or heavy preload.

The accuracy of Slide Rails is determined by the accuracy combination of both the rail and the block. Manufacturers of Slide Rails usually offer an accuracy range from normal to high accuracy between blocks and rails. The quality of the mounting surface to which the linear rail is attached to also affects the accuracy of all Slide Rails as well. Because of this, Slide Rails should have a straight and parallel mounting face in order to ensure the accuracy of the Slide Rails.

The friction of Slide Rails affect power consumption, lower operating temperatures and increase the overall efficiency. The two types of friction for Slide Rails include static and dynamic friction. The frictional resistance of Slide Rails changes depending on the type, load, speed and lubricant. The primary reason for lubrication on Slide Rails is to keep raceways, rolling elements and cages from direct metal-to-metal contact. The performance of Slide Rails can be influenced by the lubrication. For this reason, it is important to select an adequate lubricant based on elements such as the bearing, load, and speed of the Slide Rails. The type of lubrication for Slide Rails includes oil or grease depending on the needs of the application.

The price of Slide Rails varies based on a number of factors. The factors that affect the cost of Slide Rails can include different preloads, precision, block dimensions, block types, and rail lengths. For standard-size Slide Rails with normal precision and normal preload, the cost for Slide Rails can start as low as $30.00. For Slide Rails with higher accuracy and higher preloads, Slide Rails can go up to $100. The different rail-length options for Slide Rails can start at $20.00 for the shortest length and as much as $500 for the longer lengths. Prices may vary also with the type of materials used and any special requests made by the customer.

Depending on the application's environment, Slide Rails require different types of accessories. The basic accessories of Slide Rails can include covers, limit switch side mounts, lubrication systems, or coating. Each accessory for Slide Rails can play an integral role in the protection and operation of these precision devices.

Most Slide Rails will use either an accordion cover or telescoping cover. These covers protect Slide Rails from dust particles, chips, and other contaminants that may affect the precision and smooth operation of the rail and block. Accordion covers and the telescoping covers are recommended for Slide Rails to protect bearings and screws from these elements.

Limit switch side mounts can be installed on Slide Rails to accommodate applications that require this option. This allows the Slide Rails to implement hard stop, soft stop, or home positions along a linear axis.

Slide Rails have a few options when it comes to lubrication. Applications may call for a manual or automatic lubrication system. Both systems offer an efficient method of supplying oil to Slide Rails providing the advantages of smooth operation, cleanliness, and safety. The manual system on Slide Rails uses a handle pump or injector, while the automatic system may use an electric gear motor pump lubricator with a built-in time controller.

Other accessories for Slide Rails include special coatings. Rails and blocks can be treated with a special coating depending on the environmental conditions of the Slide Rails. Coatings can consist of corrosion or abrasion resistant, in addition to a dry film lubricant reducing friction and wear increasing the life of the Slide Rails.
