Feature: 1. EASY INSTALLATION: Standard MGN9 linear guide rail. The width is 9 mm and the thickness is 6.5 mm. With mounting holes with a diameter of 3mm. The installation holes are metric. The spacing is 20mm. This linear guide rail should use M3 x 8mm bolts and T nuts(without). 2. HIGH ACCURACY BEARING STEEL: The sliding guide rail is constructed of high accuracy bearing steel, which can support heavy loads and is difficult to break. 3. SELF ALIGNMENT CAPABILITY: This sliding guide features a self alignment feature that allows for placement accuracy of up to μm levels. 4. WEAR RESISTANT: This kind of slider blocks feature a lot of steel balls, low friction, is lightweight, flexible, smoothly, lacks resistance, and has a longer lifespan. 5. WIDELY APPLICABLE: MGN9 linear guide rail is widely used in all fields that require accuracy linear transmission and positioning, such as automation equipment, accuracy measuring instruments, electronic semiconductors, pharmaceutical machinery, packaging and printing, welding and cutting, machine tool equipment, industrial manufacturing, and metallurgy.
