Two 1500 mm chrome rails with four aluminium slide blocks

VEVOR

VEVOR SBR20 Linear Motion Set 1500mm 2 Rails 4 Blocks

SKU CH-ZAQX-3RZ7Z

Two 1500 mm carbon-steel rails with four aluminium blocks deliver 882 N dynamic and 1370 N static load per block for DIY CNC and automation builds

  • TypeOther Appliances
  • Width6.1
  • Two 1500 mm rails and four blocks ready for CNC builds
  • Each block handles 882 N dynamic and 1370 N static load
  • Carbon steel shaft with chrome plating resists rust and wear
  • Aluminium blocks with built-in ball bearings give low-friction travel
  • 35 mm mounting-hole spacing simplifies accurate installation

Linear Motion Set for CNC Builders

The VEVOR SBR20 kit supplies two 1500 mm chrome-plated carbon steel rails and four SBR20UU aluminum slide blocks with integrated ball bearings. It targets hobbyists and small-shop integrators assembling Cartesian robots, 3D printers or light-duty milling gantries that need ready-to-mount linear guidance.

1500 mm Rail Length Defines Travel

Each supported rail measures 1500 mm overall, fixing the maximum linear stroke in a single axis. The 20 mm shaft diameter and 35 mm mounting-hole pitch on both rail and block determine whether the set matches an existing hole pattern or a new frame design.

Sustained Load Within Rated Limits

Every block carries a dynamic rating of 882 N and a static rating of 1370 N, so continuous operation stays accurate as long as the applied force per block remains below the dynamic figure. Chrome plating and carbon-steel shafts resist wear, keeping friction low over extended duty cycles.

Questions about this item

What does the 882 N dynamic load per block mean when the set is installed in a machine?

Each SBR20UU block is rated for 882 N of dynamic load, so the four blocks together support that force while the 1500 mm rails move smoothly under load.

What mounting standard do the rails use and what spacing does it fix?

The rails have mounting holes spaced 35 mm apart in both directions, giving a repeatable 35 mm grid for bolting to a frame.

What physical space is needed to fit the 1500 mm rails and the four blocks?

The rails are 1500 mm long, 90 mm wide and 36.3 mm high; each block measures 50 x 48 x 39 mm, so allow that footprint plus clearance for the blocks to travel the full length.
