Specification Brand : YINGJUN-DRESS BulletPoint1 : Linear bearing is a kind of product which has the guiding function of sliding bearing and can make linear motion. BulletPoint2 : These linear motion systems require simple design, best execution, low maintenance costs, strict selection of durable materials, high frequency heat treatment, accurate outer diameter, roundness, straightness and surface treatment. BulletPoint3 : Linear bearing is widely used in many linear motion systems such as cylinder rod, automatic precision printer, automatic cutting machine and industrial robot. BulletPoint4 : The material of shaft is the Carbon Steel with Chromium coating, quenching and anti-rust treatment; high hardness, more durable. Industrial-grade standard SBR block, with a high precision linear bearing inside. Make the sliding smooth, low friction, silent operation BulletPoint5 : WARRANTY: Within 3 months receiving the linear rail, if there is any problem except for damage caused by man-made or improper operation, with the premise of choosing the proper product model and ensuring the working environment well ventilated and tidily, we will send new linear rail for free or give a total refund.
