Linear Rail And Linear Block is a low-cost production of linear guide and slide system for unlimited travel with the cylinder axis. Since the ball bearing point contact with the shaft, so use the load is small. Minimal friction ball rotation, thereby to obtain smooth movement precision.
Linear blocks are used in conjunction with hardened linear drive shaft. For infinite linear motion systems. Load the ball and quenching transmission shaft because linear block is the point contact, allowing the load is small, but linear motion, friction smallest, high precision, fast movement.
20mm 3000mm Linear Rail And Linear Block is a common high-precision linear motion system, widely used in industrial automation equipment, machine tools, precision instruments and other applications requiring linear motion. The system consists of 20mm wide linear rail and slider, which can withstand large loads and provide high-precision linear motion, especially suitable for long-distance smooth operation needs.
20mm linear rail is a standard width guide rail. 20mm linear rail usually made of high-strength steel or stainless steel. 20mm linear rail can provide a long time stable performance in the industrial environment. 20mm linear rail not only has a good bearing capacity, but also can adapt to the requirements of high-speed operation. The advantage of 20mm linear rail is that the width of the guideway is moderate, not only to maintain stability, but also not to increase the overall weight of the equipment. 20mm linear rail is the ideal choice for a variety of precision machinery and equipment.
3000mm linear rail (3000mm linear rail) refers to the rail length of 3000mm specifications. 3000mm linear rail is suitable for applications that require smooth movement over long distances. The long 3000mm linear rail can provide sufficient space for movement in large machinery and equipment to ensure that the slider slides smoothly along a fixed trajectory. The length of 3000mm linear rail is particularly suitable for such as gantry machine tools, automated production lines, and other equipment that require long travelling movements. This long guideway system of 3000mm linear rail is characterised by 3000mm linear rail's ability to maintain high-precision linear motion, reduce offset and error, and at the same time has a strong resistance to wear and tear, adapting to frequent use and high load conditions.
Linear block is the core component used in conjunction with the linear guide. Linear block usually composed of high strength materials and ball bearing system, which can achieve smooth and precise linear motion on the guide. The ball bearings within the block significantly reduce friction, making linear block easier to move the block along the guideway and reducing the energy consumption of the equipment. The design of the linear block is usually very compact and can withstand loads from different directions, ensuring that it maintains good performance under high loads or high speeds.
20mm linear rail, 3000mm long linear guide and slide systems play an important role in all types of precision machining and automation equipment. Linear guide and slide can provide a stable and accurate motion path for the equipment to ensure the smooth running of the machining or operation process. In addition, these linear guide and slide systems are relatively easy to install, low maintenance and have a long service life. With this linear guide and slide system, the equipment can maintain high precision and smoothness in long-distance movement, which greatly improves productivity and product quality.
The linear guide and slide system is an essential key component in modern industry. Linear guide and slidewhich ensures the stable operation of all kinds of machinery and equipment through high precision, long service life and strong load-bearing capacity, and demonstrates excellent performance and reliability, especially in long travel and high load applications.
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.
