SC 25 UU | Linear Bearing Units | SC Series

Description SC 25 UU Linear Motion Bearing Unit The SC 25 UU is a compact linear motion bearing unit that houses a 25 mm inner diameter linear ball bearing within a durable metal or aluminum housing. It is designed to provide smooth, low-friction linear movement along a cylindrical shaft, making it ideal for CNC machines, 3D printers, automation systems, robotics, and other mechanical equipment where precise straight-line motion is important. The “UU” designation indicates that the bearing is sealed on both sides, protecting the internal balls from dust and contaminants, which enhances durability and reduces maintenance. Its robust design ensures high rigidity, long service life, and reliable performance in various industrial applications. Size / Dimensions Shaft (Inner) Diameter: 25 mm Outer Width (W): ≈ 76 mm Length (L): ≈ 67 mm Height (H): ≈ 51.5 mm Bolt Hole Spacing Width: ≈ 54 mm Bolt Hole Spacing Length: ≈ 50 mm Thread Size: M8 × 18 mm Weight: ~0.555–0.60 kg Features Linear motion bearing unit: Provides smooth, low-friction movement along a shaft for accurate positioning Sealed both sides (UU): Protects internal ball bearings from dust and debris, enhancing lifespan Standardized size: Designed for Ø25 mm shafts and interchangeable with other SC25UU/LM25UU components High rigidity: Sturdy housing supports loads and resists deformation Wide industrial application: Suitable for CNC machinery, robotics, packaging equipment, and automation systems Easy assembly: Pre-installed bearing in housing simplifies installation on linear shafts
