linear guideway allows a type of linear motion that utilizes rolling elements such as balls or rollers. By using recirculating rolling elements between the rail and the block, a linear guideway can achieve high - precision linear motion. Compared to a traditional slide, the coefficient of friction for a linear guideway is only 1/50th. Due to the restraint effect between the rails and the blocks, linear guideways can bear loads in both the up/down and the left/right directions.
Advantages and Features
High Positional Accuracy: When a load is driven by a linear motion guide way, the frictional contact between the load and the bed is rolling contact. The coefficient of friction is very low, and the difference between the dynamic and the static coefficient of friction is small, so there is no slippage during load movement.
Long - life with High Motion Accuracy: Traditional slides may have accuracy errors due to oil - film backflow and wear caused by insufficient lubrication. In contrast, the rolling contact of linear guides has little wear, enabling the machine to maintain high - accuracy motion for a long time.
High - speed Motion with Low Driving Force: Linear guideways have little friction resistance, so only a small driving force is needed to move a load, which is conducive to energy saving, especially for the reciprocating parts of the system.
Equal Loading Capacity in All Directions: Linear guideways can bear loads in both vertical and horizontal directions, while conventional linear slides can only bear small loads in the direction parallel to the contact surface and are more likely to lose accuracy under load.
Easy Installation: According to the recommended installation procedure, after grinding or milling the machine surface and tightening the bolts to the specified torque, high - accuracy linear motion can be achieved.
Easy Lubrication: Compared with traditional sliding systems, linear guides are easier to lubricate, which can reduce the wear of contact surfaces caused by insufficient lubrication.
Structure and Components
Rail: It is also called a trackway or guide way, which is stationary. It can be mounted horizontally or vertically, and its length determines the travel distance of the block. It is usually made of carbon or stainless steel.
Block: It is the moving part that supports the load and moves along the rail, also known as the carriage. It is usually made of carbon or stainless steel and is equipped with a friction modifier.
Friction Modifier: It can be ball bearings, roller bearings, or lubrication, which is used to reduce the friction force during movement. The bearings rotate between the rail and the block and circulate inside the block.
Accuracy and Selection
The accuracy of linear guides can be divided into three types: running parallelism, tolerance, and difference of heights and widths. Generally, there are three accuracy grades for selection: normal (N), high (H), and precision (P). Different accuracy grades are suitable for different applications, such as high - precision grades are often used in semiconductor machines, measuring machines, etc., while normal grades can be used in some general - purpose machinery.
Applications
Linear guides are widely used in various industries, including manufacturing, machining, 3D printing, robotics, welding, medical equipment, pumps, food and beverage, automotive, oil and gas, aerospace and defense, etc. Any application that requires high precision can use linear guide systems to ensure accurate and precise movement of components.
