LMK12LUU Linear Ball Bearings 12mm Bore 21mm OD 57mm Length Extra Long Square Flange Steel Cage for CNC Machine 3D Printer

Key Features

• Dimension - Model LMK12LUU, 12 x 21 x 57 mm Metric Double Seal Chromium Steel Linear Bearing, 31 x 31mm Square Flange Base
• Usage- Linear bearings are part of linear motion systems, often used in conjunction with cylindrical shafts or guideways
• Feature - These ball bearings with steel cage run much more stable than nylon cage bearings. They are more suitable for high-speed or high-temp environments.
• Function - These bearings provide linear motion guidance and support within machinery and equipment. The steel cage ensures durability and smooth operation, while the square flange allows for mounting and alignment.
• Application - Suitable for CNC machines, 3D printers, automated equipment, robotics, and other applications requiring precise linear motion control and positioning accuracy.

Product Description

Descriptions

Linear bearings are widely used in electronic equipment, tensile testing machines and digital three-dimensional coordinate measuring equipment and other precision equipment, as well as multi-axis machine tools, punch presses, tool grinding machines, automatic gas cutters, printers and other industrial machinery sliding.Linear bearings are linear motion systems for use with cylindrical shafts. Since the carrier ball is in point contact with the shaft, low loads are applied. The steel balls rotate with very little frictional resistance, which results in a smooth motion with high accuracy.
