LMK13 Linear Bearing | LMK13UU / LMK13OP Types Available
The LMK13 linear bearing is a compact high-precision square flange linear motion component. Featuring an integrated square flange for quick positioning and secure mounting, it delivers low-friction sliding, stable operation and high repeat accuracy. Available in LMK13UU closed type and LMK13OP open type, this bearing offers reliable and cost-effective linear motion solutions for precision automation machinery.
LMK13UU vs LMK13OP | Model Differences
LMK13UU (Closed Type): Features a fully closed double rubber sealing structure to block dust and contaminants. It retains internal lubrication efficiently and supports long-term maintenance-free operation, ideal for standard workshops and dusty working conditions with regular linear stroke movement.
LMK13OP (Open Type): Adopts an open hollow structure with built-in oil grooves for easy lubrication and fast heat dissipation. It minimizes thermal accumulation during high-frequency continuous operation, suitable for high-speed and long-stroke precision linear motion applications.
Material Introduction
Bearing Steel Shell And Steel Balls: LMK13 linear bearings adopt premium bearing steel with professional heat treatment. High surface hardness and outstanding wear resistance ensure stable load performance and ultra-smooth sliding for extended service life under continuous operation.
Engineering Plastic Retainer And Rubber Seals: High-toughness engineering plastic retainer ensures low-noise, low-resistance and flexible steel ball circulation. LMK13UU is equipped with wear-resistant rubber seals for durable dustproof and anti-fouling protection.
Product Features
Precision square flange design for fast positioning and firm installation. Ultra-low friction enables smooth and consistent linear motion. High positioning accuracy and excellent repeatability. Compact structure saves installation space. Dual designs adapt to various working environments.
Application Scenarios
LMK13 square flange linear bearings are widely used in CNC engraving machines, 3D printers, precision sliding platforms, small robotic arms and automated precision equipment. LMK13UU fits conventional and dusty environments; LMK13OP is optimal for high-speed, long-stroke precision automation systems.
