LMK12 Linear Bearing | LMK12UU / LMK12OP Types Available
The LMK12 linear bearing is a high-precision square flange linear motion component. It adopts a square flange integrated structure for accurate positioning and stable mounting, featuring low friction, smooth sliding and reliable repeated operation. Available in LMK12UU closed type and LMK12OP open type, this bearing provides durable and cost-effective linear motion solutions for precision automation machinery.
LMK12UU vs LMK12OP | Model Differences
LMK12UU (Closed Type): Equipped with a fully closed double rubber sealing structure to resist dust and industrial contaminants. It locks internal lubrication firmly to support long-term maintenance-free operation, suitable for standard workshops and dusty working environments with regular linear strokes.
LMK12OP (Open Type): Designed with an open hollow structure and built-in oil grooves for convenient refueling and efficient heat dissipation. It effectively reduces heat accumulation during high-frequency continuous operation, ideal for high-speed and long-stroke precision linear motion scenarios.
Material Introduction
Bearing Steel Shell And Steel Balls: LMK12 linear bearings adopt high-quality bearing steel with strict heat treatment. High surface hardness and excellent wear resistance ensure stable load capacity and ultra-smooth sliding, extending service life during long-term continuous operation.
Engineering Plastic Retainer And Rubber Seals: High-toughness engineering plastic retainer enables low-resistance, low-noise and flexible steel ball circulation. LMK12UU is fitted with wear-resistant rubber seals for stable long-term dustproof and anti-fouling protection.
Product Features
Standard square flange design for fast positioning and firm installation. Ultra-low friction ensures stable and smooth linear motion. High positioning accuracy and excellent motion repeatability. Compact and reasonable structure saves installation space. Dual structural types adapt to different working conditions.
Application Scenarios
LMK12 square flange linear bearings are widely used in CNC engraving machines, 3D printers, precision sliding tables, small robotic arms and automated precision equipment. LMK12UU is suitable for conventional and dusty environments; LMK12OP is perfect for high-speed and long-stroke precision automation systems.
