Product Description

This item include:
1Pcs SBR12- L1000mm Fully Supported Linear Rail
2Pcs SBR12UU BlockBearing Block Bearing

The Linear system consisting of a steel linear rails with induction hardened raceways and high precision radial ball bearing sliders, also made of hardened steel. The linear guides are affordable and easy to install on all types of surfaces. 
Linear axis has been 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 made by stronger materials,it allows longer service life and reduced maintenance .

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.
