VEVOR SBR20-C 1200mm Linear Guide Set 2 Rails 4 Blocks

SKU CH-0891-55K96

Two 1200 mm carbon-steel rails with four SBR20UU blocks deliver 882 N dynamic and 1370 N static load per block for precise CNC motion

  • TypeOther Appliances
  • Width5.91
  • Smooth motion with 882 N dynamic load per block
  • Rust-resistant chrome-plated carbon steel and aluminium construction
  • Low-friction ball bearings for quiet sliding
  • High precision from 35 mm mounting-hole spacing and straight shaft
  • Ready-to-install set includes two 1200 mm rails and four SBR20UU blocks

Linear Guide Set for CNC Builders

This SBR20-C kit supplies two 1200 mm supported rails and four SBR20UU slide blocks. It is aimed at hobbyists and small-shop engineers assembling CNC routers, 3D printers or linear automation rigs who need ready-to-mount motion components.

Four Pre-Fitted Blocks Remove Assembly Steps

Each rail arrives with two blocks already installed, so there is no separate bearing press or alignment procedure. The chrome-plated carbon-steel shafts and aluminum blocks deliver 882 N dynamic and 1370 N static load per block for smooth, low-friction travel.

Rigid Aluminium Base Simplifies Mounting

The supported rail profile measures 90 mm wide by 36.3 mm high with mounting holes on a 35 mm pitch, letting you bolt the assembly directly to a machine frame without extra brackets. At 20.3 lbs the set stays stable under load while the corrosion-resistant finish withstands workshop conditions.

Questions about this item

What upkeep do the four SBR20UU blocks need over time?

The carbon-steel shafts have a chrome-plated finish for rust resistance; periodically re-lubricate the ball bearings inside each SBR20UU block to maintain smooth, low-friction motion.

Which limit appears first when the 1200 mm rails run continuously under load?

Each SBR20UU block is rated for 882 N dynamic load and 1370 N static load; exceeding the dynamic figure will cause accelerated wear before the static capacity is reached.

How much noise and heat do the rails and blocks produce during all-day operation?

Aluminum blocks on chrome-plated carbon-steel shafts with built-in ball bearings give low-friction, quiet sliding; no active cooling is required and heat generation remains minimal.
