SCS8UU 8mm Closed Linear Bearing Block

From the shop's description

SCS8UU 8mm Closed Linear Bearing Block The SCS8UU Linear Bearing Block provides smooth and accurate movement along an 8mm linear shaft. It combines a closed linear bearing with a lightweight aluminum housing. The integrated housing makes installation easier than mounting a separate linear bearing. In addition, four threaded holes allow secure attachment to a platform or moving assembly. Key Features Fits standard 8mm linear shafts Uses a closed linear ball-bearing design Provides smooth and low-friction movement Includes a lightweight aluminum housing Features four threaded mounting holes Uses retaining rings to secure the internal bearing Supports accurate and stable linear motion Simplifies installation and maintenance Suits CNC machines and 3D printers Technical Specifications Model: SCS8UU Bearing Type: Closed linear bearing block Compatible Bearing: LM8UU Shaft Diameter: 8mm Overall Dimensions: Approximately 34 × 30 × 22mm Mounting Threads: 4 × M4 Mounting Hole Spacing: Approximately 24 × 18mm Housing Material: Aluminum Approximate Weight: 46–52g Common References: SC8UU, SCS08UU and SMA8GUU How It Works The internal ball bearing travels along an 8mm linear shaft. As a result, the mounted platform can move smoothly in a straight line. The aluminum housing holds the bearing firmly. Meanwhile, the threaded holes provide a simple way to attach the block to a machine carriage. Applications Use the SCS8UU bearing block in: 3D printers CNC machines Laser engraving machines Linear motion systems Camera sliders Robotics projects Automation equipment DIY mechanical assemblies Measuring and positioning systems Installation Guidelines Use a smooth 8mm linear shaft. Align the shaft and bearing block carefully. Insert the shaft without forcing it. Attach the block through the four M4 holes. Check the movement before tightening the assembly. Apply suitable linear-bearing lubricant when required. Package Contents 1 × SCS8UU 8mm closed linear bearing block Important Notes The package includes the bearing block only. An 8mm linear shaft and mounting screws are not included. Proper alignment helps prevent friction and premature wear. Do not use damaged or rough shafts. Dimensions and weight may vary slightly between batches.
