Equipped with built-in ball bearings, the aluminum SBR slide blocks glide smoothly along the carbon steel shaft, reducing friction for a quiet and efficient operation, ensuring long-lasting, uninterrupted performance.
This linear rail kit is perfect for a variety of applications, including DIY CNC routers, 3D printers, laser engravers, and other automation projects, supporting high-load systems with ease and precision.
The all-metal design of the linear bearing ensures a strong and stable connection; The slide block is securely fastened to the linear shaft, offering excellent load-bearing capacity for demanding applications.
Pre-assembled for convenience, the guide rails include pre-drilled mounting holes; Users can easily adjust the tightness of the sliding bearings through the side screw hole of the block for a secure fit.
The chrome-plated surface of the linear rails provides robust protection against corrosion and humidity; It also offers excellent heat resistance, making it ideal for harsh working conditions or high-temperature environments.
Engineered with exacting hole distances, precise diameters, and standard shaft sizes, this guide rail system guarantees highly accurate alignment and easy installation, ensuring consistent and repeatable movements.
Heavy-Duty Load Capacity: The robust linear bearing system is designed to handle high loads, with each slide block supporting a dynamic load of 882 N and a static load of 1370 N, making it ideal for demanding machinery applications.
