Linear Bushing with Square Flange LMIK LMIK12 LMIK12UU Linear Bearing

The LM type linear ball guide sleeve is used in conjunction with the cylindrical LM optical axis to create a linear motion system that can achieve infinite linear motion. The steel ball that bears the load is in point contact with the LM optical axis, allowing for a smaller load, but it can achieve high-precision and light linear motion with minimal frictional resistance. The bearing sleeve is made of high carbon chromium bearing steel, and after heat treatment, its inner and outer surfaces are ground. The application range of linear ball guide sleeve is wide, including precision instruments such as office equipment and its peripheral equipment, various measuring instruments, automatic recording devices, and digital 3D measuring instruments; And the sliding parts of industrial machinery, including multi axis drilling machines, punching machines and tool grinders, automatic gas cutting equipment, printing machinery, card sorting machines, and food packaging machines.

• Due to the standard dimensional tolerances of each part of the linear ball guide sleeve, it is interchangeable. The LM optical axis can be easily ground using an external cylindrical grinder, and high-precision clearance (pre pressing) can be obtained.
• The retainer that guides the 3-8 rows of steel balls is an integral casting structure, which can correctly guide the steel balls in the direction of movement and achieve stable walking accuracy.
• Small diameter products use integral cast synthetic resin retainers, which can reduce noise during operation and have excellent lubrication effects.
• THK offers a wide variety of LM ball bushings, such as standard, pressure adjustable, open, long, and flange types. Users can choose the appropriate type according to their usage.
• When making LM optical shafts with linear ball guide sleeves, due to the steel ball rolling directly on the surface of the shaft, it is necessary to fully consider the hardness, surface roughness, and dimensional accuracy of the shaft.
• THK manufactures a standard LM optical axis specifically for linear ball guide sleeves.
