Product Overview
The SCS16LUU is a long type enclosed linear bearing block designed for 16mm linear shafts. As the extended-body version of the SCS16UU, it delivers a longer contact length between the housing and the LM16UU×2 bearing units inside, providing enhanced load distribution and improved running stability across the full stroke.
The enclosed aluminum housing has no clamping mechanism - the block slides freely along the shaft without any locking function. This makes the SCS16LUU 16mm bearing block the preferred choice for applications requiring smooth, unobstructed linear travel.

Product Features
Long Type Enclosed Housing
The SCS16LUU adopts a closed-body aluminum housing that fully encases the dual LM16UU bearing units. The longer body length - 85mm versus the standard SCS16UU - increases the effective bearing span, reducing tilt and improving motion linearity under load.
Free-Sliding Linear Motion
Do not use double sided tape to attach light panels to dusty, damp, wallpapered or uneven surfaces such as brick, unfinished wood or rough concrete walls;.
Dual LM16UU Bearing Configuration
Two LM16UU linear bearings are pre-installed inside the SCS16LUU block, delivering a combined dynamic load capacity of 774N and static load capacity of 1180N. The dual-bearing arrangement supports higher radial loads than a single-bearing housing of the same shaft size.
Mounting Compatibility
Four bolt holes on the housing base (M5, S₁ pattern) allow direct bolt-down mounting to linear motion stages, machine frames, and custom fixtures. Shaft compatibility: Ø16mm precision linear shaft.

FAQ
Q: What is the difference between SCS16UU and SCS16LUU?
A: The SCS16LUU is the extended-body version of the SCS16UU. It has a longer housing (L=85mm vs L=58mm) and houses two LM16UU bearings instead of one, giving greater load capacity and more stable linear motion along 16mm shafts.
Q: Does the SCS16LUU have a shaft clamping function?
A: No. The SCS16LUU housing has no clamping or locking mechanism. The block slides freely along the 16mm shaft and cannot be locked at a fixed position.
Q: What shaft diameter is compatible with SCS16LUU?
A: The SCS16LUU is designed for 16mm precision linear shafts (Ø16mm), and is compatible with standard SBR16 rail systems and open linear shaft configurations.
