The material is the 45# high quality steel, Extend the service life of the shaft and the machine.
The shaft is case hardened, If you use normal steel shaft,The bearings will be reduce in use process
Metal linear bearing, it's more durable than Plastic linear bearing.
high precision and easy to mount & dismount.
Move smoothly without deflection, minimal wear and low noise.
This product chrome plated optical axis surface after a special grinding and hard chrome plating treatment, and then made it mirror polished,with abrasion,corrosion resistance properties. Linear axis has widely used in the automatic transmission, Applicable to all kinds of cylinder,engraving Machine,piston,packaging, woodworking,textile, printing and dyeing machinery, die-casting machines, injection molding machines,punch, tool grinding machine, automatic cutting machine, printer, card sorting machine, Food Packing Machine,and other machinery with the guide rod and other sliding parts on industrial machinery. And because it's stronger materials,But also to extend the life of ordinary precision machinery together.
1.SBR/TBR Cylindrical linear guide rail is composed of a rail support,a shaft (rail),and number of blocks. They are provided as a unit or as respective components as well. All components are standardized to be fully interchangable. 2.Support Rail Support Rail provides maximum rigidity and stiffness to the shaft throughout the whole stroke, and ensure the performance of the unit. 3.Case (SBR/TBR /SMD) Effective for high load or long stroke application with maximum rigidity and excelent motion in combination with Open type Linear Bushing. Moreover,preload can be applied on SBR/TBR/SMD series for high precision performance. 4.Support Rail Unit (SBR-S/TBR-S) SBR-S and TBR-S type are optimum guide units for high precision and deflection free sliding system with smooth motion and maximum rigidity,and less cost and time.

I cut two of these long rails to make short and long pairs for an XY application. The rods are hardened so this may be hard to do at home. Mine were cut in a machine shop.
