LMH12 Linear Bearing | LMH12UU / LMH12OP Types Available
The LMH12 linear bearing is a high-precision extended flange-type linear motion component. Featuring a lengthened body and one-piece flange structure, it provides higher load capacity and operational stability than standard flange bearings with ultra-low friction sliding. Available in LMH12UU closed type and LMH12OP open type, it delivers reliable and cost-effective linear motion solutions for precision automation machinery.
LMH12UU vs LMH12OP | Model Differences
LMH12UU (Closed Type): Built with a fully closed double rubber sealing structure for superior dust and contaminant resistance. It locks in internal grease to maintain long-term lubrication, supporting maintenance-free operation. Perfect for standard workshops and dusty industrial environments with regular linear stroke movement.
LMH12OP (Open Type): Designed with an open hollow structure and built-in oil grooves for easy re-lubrication and efficient heat dissipation. It effectively reduces heat accumulation during high-frequency continuous cycling, ideal for long-stroke, high-speed precision linear motion applications.
Material Introduction
Bearing Steel Shell And Steel Balls: LMH12 linear bearings adopt premium bearing steel with professional heat treatment. High surface hardness and excellent wear resistance ensure stable load performance and ultra-smooth sliding, greatly extending service life under continuous operation.
Engineering Plastic Retainer And Rubber Seals: High-toughness engineering plastic retainer enables flexible, low-noise steel ball circulation with minimal running resistance. LMH12UU is fitted with wear-resistant rubber seals for stable long-term dustproof protection.
Product Features
Extended body design for enhanced load capacity and rigidity. Integrated flange enables fast, hassle-free installation. Ultra-low friction ensures smooth and stable linear motion. High positioning accuracy and excellent motion repeatability. Dual structure designs suit multiple working conditions.
Application Scenarios
LMH12 extended flange linear bearings are commonly used in CNC engraving machines, 3D printers, precision sliding tables, robotic arms and automated precision equipment. LMH12UU works best for conventional and dusty environments; LMH12OP is ideal for high-speed and long-stroke precision automation systems.
