Description:Bearing Steel Material: The linear guide rail and slider are made of bearing steel, which has the advantages of wear resistance, pressure resistance, strong load-bearing capacity and not easy deformation, and has good dimensional stability. A layer of yellow anti-rust oil is applied to the surface to ensure smooth operation and prevent rusting. The yellow coating on the product surface is anti-rust oil, not rust.Feature: The slide rail and sliding carriage block are of high precision, and the block has built-in steel balls to reduce friction, ensuring high-speed and stable operation without jamming and quiet noise. Plastic mini linear guides assist in installation to prevent the steel balls from falling off.
