The SCS series aluminium linear bearing blocks are designed for CNC routers and other motion systems that require precise, lowfriction linear guidance on standard rail shafts. Available in SCS8UU, SCS10UU, SCS12UU, SCS16UU and SCS20UU variants, including the SCS12UU version, these lightweight blocks combine a robust aluminium housing with precision ball bearings to deliver smooth motion and reliable performance on Guild Rail Shaft systems. Key benefits Smooth, lowfriction movement: precision ball bearings inside the block provide consistent guidance and reduced wear. Lightweight aluminium housing: lowers inertia for faster, more controlled movement and easier mounting. Durable construction: aluminium alloy housing offers strength and long life in workshop environments. Wide variant range: multiple sizes (SCS8UU, SCS10UU, SCS12UU, SCS16UU, SCS20UU) to match different shaft diameters and load needs. Easy mounting and interchangeability: designed to fit standard rail shafts and work with common CNC and automation configurations. Reliable performance on Guild Rail Shaft systems: engineered to align with the SCS family for smooth operation. Key attributes Functionality: linear ball bearing block for precise linear motion on rail shafts. Compatibility: variants include SCS8UU, SCS10UU, SCS12UU, SCS16UU, and SCS20UU, suitable for Guild Rail Shaft installations. Size options: available across 8 mm, 10 mm, 12 mm, 16 mm, and 20 mm shaft configurations. Material: lightweight aluminium. Performance: designed to provide smooth, accurate guidance with dependable load handling on standard rails. Applications CNC router gantry or carriage on a guide rail system. XY positioning table on small milling, drilling, or routing machines. Linear axis for 3D printers, laser cutters, or automated assembly lines requiring precise motion. Notes The product line covers multiple SCS variants; the SCS12UU version is part of the available options and can be matched to your rail shaft configuration.
