NGS linear motion guide uses the roller to replace the ball, and the contact mode between the rollers and the raceway changes from point contact to linear contact, which greatly improves the rigidity of the rolling linear guide and enables the machine to maintain higher accuracy. NGS linear bearing slide rails contact angle between roller and raceway is 45°, so linear bearing slide rails has equal load in four directions. Roller cage prevents roller deflecting motion and moves stably. At the same time, linear bearing slide rails forms the oil film contact between roller and cage, avoid friction among rollers, reduce the heat roller and cage, avoid friction among rollers, reduce the heat precision movement.
Low-Friction Linear Motion Guide And Slide Rails is a system designed to provide high-precision, low-friction linear motion in a wide range of automation, precision instrumentation, and robotics applications. Linear slide bearings and linear bearing slide rails are key components of the system, responsible for ensuring smooth, precise movement with minimal friction as the equipment performs its task.
The core design of linear guides and rails (linear guides and rails) is to minimise friction through the mating of bearing slides to the rail surface to achieve efficient linear motion. These linear guides and rails systems are usually made of high-strength materials, such as steel or stainless steel, to ensure sufficient durability and corrosion resistance over long periods of use. Balls or rollers inside the slider and linear slide bearings allow for smooth linear motion as the moving parts slide on the rail, and reduce wear and tear for a longer service life.

Linear motion guides (linear motion guides) have a particular focus on low friction and high accuracy, which makes them excellent where high precision operations are required, such as 3D printers, CNC (numerical control) machining equipment and semiconductor manufacturing equipment. These linear slide bearings maintain a high degree of accuracy over long running times. Linear guides and rails are suitable for tasks with high repeatability and stringent accuracy requirements.
In addition, these linear slide bearings systems are designed with ease of maintenance and installation in mind. They are usually compact, which not only saves space but also enables them to be easily integrated into different mechanical devices. Due to their low friction, the systems operate with less noise and run more smoothly, making them suitable for applications in quiet working environments.
Load capacity is determined by dynamic (C) and static (C₀) load ratings. For example: A 6205 deep groove ball bearing has a dynamic load rating of 14 kN, suitable for small motors. For heavy loads, choose tapered roller bearings (e.g., 32208 with C=90 kN). Recommendation: Share your equipment’s load analysis for optimal bearing selection.
Materials: Stainless steel (440C/316) or coatings (nickel plating, DLC). Seals: Double rubber seals (2RS) or PTFE seals. Example: Seawater pumps often use 316 stainless steel bearings with lifelong grease.
Speed limits depend on bearing type and lubrication: Standard 608ZZ ball bearings: ~18,000 rpm. Hybrid ceramic bearings (Si3N4 balls): 30–50% higher speeds. Solution: For high-speed applications, opt for oil lubrication or low-friction design.
Theoretical lifespan: Based on load calculations (see Q1). Real-world factors: Lubrication intervals (e.g., grease replenishment every 100km). Mounting surface flatness (≤0.01mm/m required). Tool: Free lifespan calculation software available.
Must-check: Slider hole spacing (e.g., 45mm×45mm). Rail width (15/20/25mm, etc.). Slider height (impacts machine space). Pro tip: Old slider model numbers are often engraved on the side.
