SBR..UU / SBR..LUU Slider – Linear Bearing Slider

The SBR slider is the sliding component of our economical linear guide rail system, paired with SBR series guide rails. This series is designed for complete assembly interchangeability with mainstream SBR slider products. Available in standard type (SBR..UU) and extended type (SBR..LUU) specifications, suitable for economical linear motion applications including automation equipment, CNC engraving machines, and 3D printers.

Key Features

  • Assembly Replacement – Direct replacement of existing same-series sliders in customer equipment
  • Standard Type (UU) – Single bearing design, standard housing length, suitable for light load and conventional stroke applications
  • Extended Type (LUU) – Built-in double bearings, extended housing length, dynamic load rating double that of standard type, significantly improved rigidity and stability
  • Double End Seals – UU indicates seals on both ends, effectively preventing dust ingress and extending service life
  • Aluminum Housing – Housing made of aluminum alloy for lightweight design and good heat dissipation

  • Shaft end machining — machined precisely to your drawing
  • Screw length — cut to your exact requirement
  • Preload — light, medium, heavy, or custom value
  • Nut type — standard flange, special shape, or non-standard mounting interface
  • Rail length — continuous cutting with end finishing (chamfer or grinding)
  • Mounting holes — special thread sizes, hole spacing, or countersunk dimensions

Send us your drawing or specs — we'll deliver exactly what you need.
