Specification Brand : VEVOR BulletPoint1 : SBR Linear Rail Set: This set includes 2 units of 1200mm long SBR25 rails and 4 SBR25UU sliding blocks. Each block has a dynamic load capacity of 980N and a static load capacity of 1570N, providing strong load-bearing performance. The long and precise rails are compatible with a wide range of large equipment, efficiently handling heavy loads while ensuring stable and smooth linear motion. BulletPoint2 : Sturdy and Durable: The linear rail is made from carbon steel and aluminum composite, with a chrome-plated surface to enhance wear-resistant and corrosion-resistant ability. It features 4 aluminum sliding blocks equipped with ball bearings to reduce friction, disperse pressure, and effectively resist impact. The structure is solid, wear-resistant, and deformation-resistant, meeting the demands of high-intensity operations and ensuring long-lasting, stable performance. BulletPoint3 : Low Noise Operation: Aluminum sliding blocks paired with carbon steel shafts offer complementary material properties for stable performance. The built-in ball bearings enable low-friction movement, reducing collisions and wear between components, effectively lowering operating noise and ensuring smooth and quiet operation, creating a calm and efficient working environment for the equipment. BulletPoint4 : High Precision: Precise round shaft dimensions and excellent straightness ensure accurate motion with no deviation. The aluminum base and sliding blocks have preset installation holes for accurate positioning, ensuring zero installation error and effectively reducing cumulative errors. BulletPoint5 : Wide Applications: This SBR linear rail set is versatile and ideal for high-load automation equipment like production lines, machine tools, and DIY projects. With outstanding performance, it provides stable and reliable linear motion support for various scenarios, easily meeting diverse needs.
