Linear bearing SCS10UU for 3D printer, OEM (SCS10UU) – 10 mm bore, flanged bronze/steel

Flanged linear bearing SCS10UU is designed for 3D printers and light CNC machines that use 10 mm guide shafts. The bearing combines a steel outer shell with bronze/PTFE-lined inner surfaces to deliver low-friction linear guidance and stable support for carriages, gantries and extrusion assemblies. Its flanged design allows simple mounting and alignment on frames and plates, making it suitable for X, Y and Z axis motion where compact, repeatable movement is required.

Advantages

This SCS10UU flanged linear bearing provides smooth, low-friction travel along 10 mm shafts due to PTFE-lined contact surfaces and the bronze/steel construction that resists wear. The flange simplifies installation and positional adjustment on flat mounting surfaces. Its compact size and standardized bore ensure compatibility with common printer and CNC rod diameters, supporting accurate positioning and reduced maintenance compared with plain bushings.

Suitable for

• X, Y and Z axis carriages and gantries in 3D printers
• Linear slides and extrusion assemblies in desktop CNC machines
• Guiding shafts for small automation or robotics projects
• Replacement of worn linear bushings in hobbyist equipment

Key specifications

• Bore diameter: 10 mm designed to fit 10 mm hardened steel shafts
• Construction: steel outer shell with bronze/PTFE-lined inner surface for low friction
• Mounting: integrated flange for secure screw attachment to flat plates
• Function: plain linear bearing for smooth axial movement and radial load support
• Typical applications: light-duty positioning and guidance where compact bearings are required

How to use

Install the bearing by sliding it onto a clean, straight 10 mm shaft and secure the flange to the mounting plate using appropriate screws. Ensure shaft surfaces are free of heavy corrosion or burrs and are properly aligned to prevent binding. Operate within light to moderate loads and avoid side impacts; regular inspection of shaft condition and bearing fit helps maintain smooth motion. If required, apply a compatible lubricant to the shaft to extend service life in dusty or high-use conditions.

Usage recommendations

For reliable performance, pair the SCS10UU bearing with a hardened, ground 10 mm shaft and maintain correct alignment of bearing blocks. Avoid exposing the bearing to excessive contaminants or corrosive environments. Periodic inspection and light lubrication will prolong service life and preserve dimensional accuracy of motion systems.
