The Linear Bearing Long Block is a robust and precise linear motion component available in three popular sizes — SCS6UU (6mm), SCS8UU (8mm) and SCS10UU (10mm) — featuring an extended block body for enhanced stability and load distribution compared to standard short blocks. The elongated design provides greater contact area with the shaft, resulting in improved rigidity and reduced play during linear movement.

Each block houses a precision LM6UU or LM8UU or LM10UU linear bearing within a solid aluminium alloy housing, complete with pre-drilled mounting holes for easy installation onto frames, carriages, and custom platforms. The open-type block design allows quick shaft insertion and removal, making assembly and maintenance straightforward.

Widely used in 3D printers, CNC routers, laser engravers, camera rigs, and automation systems, the SCS6UU, SCS8UU and SCS10UU long blocks are a reliable choice for makers, engineers, and motion system builders seeking stable and accurate linear guidance.
