Linear Bearing Rail
Linear guide is consisted of rail, block, rolling elements, retainer, recirculator, end seal etc. By using the rolling elements, such as balls or rollers between the rail and block, the linear guide can achieve high precision linear motion.Linear guide block is divied to flange type and square type without flange.or Seal type block, Standard type block, Double bearing type block, Short type block. Also,linear block is divided to high load capacity with standard block length and ultra high load capacity with longer block length.

High Rigidity and Low Friction Performance: This aluminum rail linear guide offers high rigidity and low friction performance, making it ideal for applications requiring precision and smooth movement. Its unique design ensures stable and consistent operation, reducing wear and tear on machinery.
Suitable for Various Industries:
This linear guide is applicable to a wide range of industries, including building material shops, manufacturing plants, machinery repair shops, farms, retail, printing shops, and advertising companies. Its versatility and adaptability make it an excellent choice for businesses with diverse needs.
Enhanced Performance:
The linear guide rail boasts low friction, low noise, high speed, and high precision, making it an ideal choice for CNC machining parts and other demanding applications.
High-Quality Material:
The SBR12 SBR16 SBR20 SBR25 CNC Aluminum Round Linear Guide Rail is made from high-quality aluminum, ensuring durability and resistance to corrosion. This makes it suitable for various industrial applications.
Self-aligning ability
When the DF (45-45) combination from the arc groove is installed, even if the installation surface is somewhat deviated, it can be absorbed by the inside of the rail slide block by the elastic deformation of the steel ball and the transfer of the contact point, resulting in the effect of self-aligning ability and high-precision and stable smooth movement.
It is interchangeable.
Because the manufacturing precision is strictly controlled, the dimension of the linear guide rail can be maintained at a certain level, and the slide block is designed with a retainer to prevent the steel ball from falling off, so some series of precision are interchangeable. Customers can order the guide rail or slide block according to their needs, or store the guide rail and slide block separately to reduce the storage space.
High rigidity in all directions.
Using four rows of circular arc grooves and four rows of steel balls at 45-degree contact angles, the steel balls can reach the ideal two-point contact structure, and can bear the loads from up and down and left and right directions; If necessary, preloading can be applied to improve the rigidity.
Types of Linear Bearing Rail
There are several different types of linear guide rails, each with its own advantages and disadvantages. The most common types of linear guide rails are:
Ball bearing guide rails:
These guide rails have ball bearings that run along the length of the rail. They offer low friction and are ideal for applications where high speed and accuracy are required.
Roller guide rails:
These guide rails have rollers that run along the length of the rail. They offer low friction and are ideal for applications where high speed and accuracy are required.
Sliding contact guide rails:
These guide rails have a sliding contact that runs along the length of the rail. They offer high friction and are ideal for applications where low speed and high accuracy are required.
