LINEAR RAIL KIT -This linear rail set includes 4 pieces of SBR20 1500mm rail shafts,8 pieces SBR20UU blocks,4 pieces dowels,32 Pieces Screws,2 pieces Handles,2 pieces Wrenches. Two 1500mm rails can be spliced together to form a 3000mm length using dowels. EASY TO INSTALL- Aluminum alloy support rail with pre-drilled holes for ease of mounting. Stainless steel Linear optical axis guide bearings linear movement. Easy to install, no need to maintenance. HIGH QUALITY- The linear rail and bearing block adopt high quality metal shell for long lifespan, wear resistant and durable in use. RUST PROOF- The linear rail kit adopts Appearance oxidation treatment, Glossy Appearance allows bearing block to move quickly with less friction, beautiful and rust-proof. WIDE APPLICATION- Linear bearing rail is widely used for large-scale transmission equipment such as CNC machines, industrial robots, cracker machines, supersonic cleaning equipment, solar energy, clothing supporting devices and more. Linear bearing is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. Because of point contact between ball and straight axis, so the load is small. The ball is spinning with the smallest friction, it can run a high precision and smooth motion. Flange linear bearings can be divided into: round flange type, oval flange, guide wheel flange, guide the oval flange type, plus long round flange type.
This is the sliding unit with the aluminium case, shafts and aluminium rail for preventing deflexion. This is the complete sliding unit systems and can be clamped simply tightening by bolt with high accuracy. The support rail unit provides maximum rigidity and stiffness to the shaft throughout the whole stroke, and ensure the performance of the unit.
The shaft is case hardened. If you use normal steel shafts, the bearings will cut them up in no time. So make sure what you buy is case hardened!
