The TRB Linear Cylindrical Guide is a precision linear transmission component with a cylindrical optical shaft as the core guiding element. Through the precise cooperation between the slider and the cylindrical guide, it achieves smooth movement and accurate positioning in the linear direction. Made of high-strength alloy steel through precision grinding and surface strengthening treatment, the slider is equipped with high-performance bearings or self-lubricating bushings, which can effectively reduce the motion friction coefficient while bearing radial and axial composite loads. With a compact structure and easy installation, it adapts to different stroke and load requirements, and is widely used in automated production lines, precision sliding tables, medical equipment, logistics conveying equipment and other scenarios. It is especially suitable for working conditions with limited installation space and high requirements for motion stability, and is a key guiding component to improve equipment transmission accuracy and operational stability.
Product Advantages
It features a compact structure and easy installation, and adapts to different stroke and load requirements.
High-precision guidance, smooth movement
The guide surface undergoes precision grinding, with a straightness error of ≤0.02mm/m and a roughness as low as Ra 0.4μm; the gap between the slider and the guide is controllable (0.001mm-0.005mm), with no jamming or movement during operation, ensuring equipment positioning accuracy and motion consistency.
High rigidity and load-bearing, strong impact resistance
The guide is made of 40Cr or SUJ2 high-strength steel, with overall quenching treatment (hardness HRC58-62), and the maximum rated radial load is 80kN; the slider is equipped with multiple sets of bearings or thickened bushings, which can withstand instantaneous impact loads and adapt to long-term stable operation under heavy-load conditions.
Compact structure, flexible installation
The cylindrical structure saves 40% of the installation space compared with square guides, and can realize single-axis, dual-axis or multi-axis parallel installation; the slider has built-in positioning holes and installation grooves, which can be fixed without complicated adjustments, greatly shortening the equipment assembly time.
Multi adaptability and easy maintenance
Support customization of 304 stainless steel material, resistant to salt spray corrosion for up to 1000 hours, suitable for food and medical clean environments; The self-lubricating sleeve type slider can achieve 10000 hours of maintenance free operation. The bearing type slider comes with an oil injection hole, which does not need to be disassembled when adding lubricating grease, reducing maintenance costs.

Selection & Installation
1
Selection Points
Select the appropriate model according to load type (radial/axial dominated), load size, operating speed and working conditions - SUJ2 material + bearing-type slider is preferred for heavy-load scenarios; 304 stainless steel material + self-lubricating bushing-type slider is selected for clean/corrosive environments; for high-speed scenarios, the matching between friction coefficient and maximum operating speed needs to be confirmed.

Installation Note
The flatness of the mounting surface should be ≤0.03mm/m, and the roughness Ra≤1.6μm; use positioning brackets to fix the guide, and the distance between the brackets at both ends is ≤1000mm (intermediate supports need to be added for extra-long guides); after installation, use a dial indicator to detect the straightness of the guide, ensuring the error ≤0.02mm/m and no jamming during slider operation.
