LMK40 Linear Bearing | LMK40UU / LMK40OP Types Available
The LMK40 linear bearing is a heavy-duty square flange type linear motion component, widely used in industrial precision automation. It features an integrated square flange for fast installation and precise positioning, providing high rigidity, large load capacity and stable low-friction linear movement. Available in LMK40UU closed type and LMK40OP open type, it delivers reliable and cost-effective linear motion solutions for heavy-duty mechanical equipment.
LMK40UU vs LMK40OP | Model Differences
LMK40UU (Closed Type): Designed with a double rubber fully sealed structure for excellent dustproof and anti-fouling performance. It retains internal lubrication to support long-term maintenance-free operation, suitable for ordinary workshops and dusty industrial working conditions with regular linear strokes.
LMK40OP (Open Type): Adopts an open hollow structure with built-in oil grooves for easy lubrication and efficient heat dissipation. It effectively reduces heat buildup during high-frequency continuous operation, ideal for high-speed, long-stroke and heavy-load precision linear motion scenarios.
Material Introduction
Bearing Steel Shell And Steel Balls: LMK40 linear bearings adopt high-grade bearing steel with strict heat treatment. High surface hardness and outstanding wear resistance ensure stable heavy-load operation and ultra-smooth sliding, extending service life under long-term industrial operation.
Engineering Plastic Retainer And Rubber Seals: High-toughness engineering plastic retainer ensures low-noise and low-resistance steel ball circulation. LMK40UU is equipped with wear-resistant rubber seals for durable dustproof and anti-fouling protection.
Product Features
Integrated square flange for accurate positioning and firm mounting. Industrial-grade heavy-load structure with high rigidity. Ultra-low friction for smooth and stable linear motion. High precision and excellent motion repeatability. Two structural options fit different operating environments.
Application Scenarios
LMK40 square flange linear bearings are commonly applied in heavy-duty CNC machine tools, large engraving machinery, automated sliding platforms, industrial robotic arms and automation production lines. LMK40UU is suitable for conventional and dusty environments; LMK40OP is perfect for high-speed, long-stroke heavy-duty precision automation systems.
