Material: This slider is made of 440C stainless steel, which is wear-resistant, rust-proof, and corrosion-resistant, and not easily deformed or broken. It can maintain high rigidity even under repeated linear motion and has a long service life.
Feature: This carriage block uses P4-grade precision steel balls, increasing the number of ball circuits to reduce friction and achieve smooth, low-resistance movement. The high alignment and positioning accuracy between the guide and the slider reduces wear and ensure efficient movement. The precision-designed steel structure ensures durability, low noise, and extremely low maintenance requirements. The carriage block adopts an extended length design for better load distribution and stability.
Application: The linear slider block is suitable for CNC routers, 3D printers, linear slide systems, automation machinery, experimental equipment, and custom DIY motion control projects.
Installation Steps: Align the carriage block parallel with the guide rail, then gently push the carriage onto the rail until fully inserted. Installation is complete once the steel balls remain in place without falling out. For actual sliding motion, replace the plastic rail with a genuine guide rail. No tools or additional hardware included.
