SBR20UU — 20mm Short Supported-Rail Bearing Mount
A compact open linear-bearing mount for a compatible 20mm SBR supported round rail. The short aluminium housing carries the matching LM20UU-OP bearing format so the carriage can travel over the rail support profile.

The complete source sheet below identifies the short SBRXUU family. The translated row is the exact SBR20UU reference; catalogue basic load values are shown in Newtons with a simple kgf equivalent.
| Model | Bore | h | E | W | L | F | h1 | Angle | B | C | Thread | L1 | T | Insert | Dynamic C | Static C0 | Weight |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| SBR20UU | 20mm | 23mm | 24mm | 48mm | 50mm | 39mm | 10mm | 60° | 35mm | 35mm | M6 | 12mm | 11mm | LM20UU-OP | 882N ≈ 90kgf | 1370N ≈ 140kgf | 200g |
Where SBR20UU is used
- Runs on a compatible 20mm SBR supported round rail.
- Short housing suits compact carriage plates and closer mounting points.
- Open underside allows the bearing to pass over the aluminium rail support.
- Commonly used in CNC, automation, positioning and workshop linear-motion assemblies.
How to read the catalogue ratings
Dynamic: 882N (about 90kgf equivalent force). Catalogue comparison value while the bearing is moving.
Static: 1370N (about 140kgf equivalent force). Catalogue comparison value while the bearing is stationary.
These are bearing basic load ratings, not lifting ratings or guaranteed working payloads. Actual usable load depends on rail support, carriage spacing, alignment, mounting stiffness, travel speed, shock and the complete machine design.
