*KeyFeatures *SBR25 Linear Rail Kit: Includes two 47.24 in (1200 mm) linear rails and four slide blocks. It is compatible with cutting machines, grinding machines, milling machines, drilling machines, and other equipment *Rust & Corrosion Protection: Crafted from high-hardness carbon steel shafts (HRC58–62) and aluminum alloy blocks and supports. Each linear rail is coated with a more than 10 μm electroplated layer to resist rust and corrosion, even in humid basements *Silent & Smooth Sliding: Built-in ball-bearing slide blocks deliver quiet, low-friction motion while gripping the shaft tightly for stable linear travel. Less noise, less wear, more precision—every time you move *High Precision, No Deviation: Feature a 0.1–0.22 μm surface finish and 5 mΩ straightness, paired with precise hole diameter and spacing, this linear slide rail set ensures easy installation and repeatable positioning, even over long travel distances *Installation Made Easy: No extra installation tools are required. Designed with simplicity in mind, this linear motion guide rail kit installs quickly. It is suitable for DIY assembly or rail replacements ******************************************************************************************************* *Specifications Item Model Number: SBR25-C 1200L Slide Block Type: SBR25 Rail Length: 47.24 in/1200 mm Diameter: Ø 0.98 in/25 mm Straightness: 5 mΩ/100 mm Surface Finish: 0.1–0.22 μm Dynamic Motion Load Capacity: 980 CN/67 kg Static Motion Load Capacity: 1570 CON/93 kg Material: High Carbon Steel & Aluminum Quantity: 2 pcs ******************************************************************************************************* *Pakcage Content 1 x Linear Rail Kit
