Specification Brand : KUAOXK BulletPoint1 : 1. Made of bearing steel with low friction coefficient, there is no resistance when placing the bearing on the guide rail. BulletPoint2 : 2. Durable and smooth, it is very suitable for most 3D printers. It is very suitable for slider movement and translation. BulletPoint3 : 3. Smooth operation, low noise and no pollution, linear guides and rails provide smooth and precise guide surfaces on which the rolling elements of linear bearings can slide. BulletPoint4 : 【Material】 Aluminum alloy bracket, MGN 9H linear guide rail with oxidized surface. BulletPoint5 : Friendly reminder:Upgrade the Y-axis linear guide on your Ender 3 S1 3D printer by elevating the 20*40 aluminum profile for a smooth installation of the linear guide. Watching the installation video will assist you in successfully completing the linear guide upgrade.Download the model file at Thingiverse: 5794235.If there is any quality problem with the product, please contact us, and we will solve it for you.
