SBR20 Linear rails (Fully supported)
These fully supported SBR rails are made of a precision machined, hardened steel, cylindrical shaft secured to a sturdy extruded 6061 aluminium base.
Designed as a cheaper alternative to profile rails they perform quite well in CNC and motion control applications where a smooth, predictable motion is desired.
These rails are capable of resisting large lateral forces and are generally more tolerant to non-precision milled mounting surfaces due to their cylindrical shape making for easier installation.
The bearing blocks that suit these rails are made of a durable cast aluminium housing with rows of carbon steel ball bearings secured into an ABS housing and provide there lateral force resists on a carbon steel race sleeve inside the housing.
For optimal perfomance, we recommend cleaning the existing machine oil off thoroughly and applying fresh machine oil or grease. To extend the life of these rails we recommend ensuring there is adequate oil/grease on the rails.
We can do pretty much any size you need!
