Special Features

  • Crafted from high-carbon chrome bearing steel (SUJ2/52100) and precision chrome steel balls, this KH series open-type linear bearing delivers exceptional hardness, wear resistance, and anti-corrosion performance. Its robust metal construction handles heavy loads and prolonged industrial use, outperforming plastic bearings in high-stress environments, while precision-ground components prevent premature wear for consistent reliability.
  • Engineered to meet international KH series standards, this linear bushing features a precise inner diameter (e.g., 10mm/12mm/16mm) that perfectly matches corresponding linear guide shafts. Strict manufacturing tolerances eliminate wobble and excessive clearance, ensuring a tight, stable fit for smooth linear movement. It serves as a direct drop-in replacement for standard LM series open-type bearings, compatible with most linear motion systems, CNC routers, and 3D printers.
  • The unique open-slot (open-type) structure simplifies installation, adjustment, and maintenance, allowing fine-tuning of radial clearance to match your application needs. This design promotes superior heat dissipation, preventing overheating during high-speed continuous operation, while the exposed ball cage enables quick cleaning and debris removal, reducing jamming risk and extending the bearing's service life.
  • Featuring a precision ball retention cage and smooth ball circulation, this KH series bearing minimizes friction and vibration, delivering ultra-smooth, quiet linear movement with exceptional positional accuracy. Its low-friction design reduces energy consumption and component wear, making it ideal for high-speed automation equipment—ensuring precise positioning for CNC machining, 3D printing, and precision measurement instruments.
  • This KH open-type linear ball bearing is widely used in industrial automation and DIY projects, including CNC routers, engraving machines, 3D printers, linear modules, packaging machinery, and precision testing instruments. Its compact, standardized design enables quick, tool-free installation: simply slide onto the linear shaft and secure with mounting brackets, perfect for professional industrial use and hobbyist DIY setups.
