LMK25 Linear Bearing | LMK25UU / LMK25OP Types Available
The LMK25 linear bearing is a heavy-duty square flange linear motion component. It features an integrated square flange for precise positioning and rigid mounting, delivering high rigidity, large load capacity and low-friction stable movement. Available in LMK25UU closed type and LMK25OP open type, this bearing provides durable and cost-effective linear motion solutions for heavy-duty precision automation and industrial machinery.
LMK25UU vs LMK25OP | Model Differences
LMK25UU (Closed Type): Comes with a fully closed double rubber sealing structure to block dust, debris and industrial contaminants. It locks internal grease firmly to maintain long-term lubrication and maintenance-free operation, suitable for standard workshops and dusty working conditions with regular linear strokes.
LMK25OP (Open Type): Adopts an open hollow structure with built-in oil grooves for easy lubrication and efficient heat dissipation. It effectively lowers thermal accumulation during high-frequency continuous operation, ideal for high-speed, long-stroke and heavy-load precision linear motion applications.
Material Introduction
Bearing Steel Shell And Steel Balls: LMK25 linear bearings are made of high-grade bearing steel with professional heat treatment. High surface hardness and outstanding wear resistance support stable heavy-load operation and ultra-smooth sliding, greatly extending service life in continuous industrial working conditions.
Engineering Plastic Retainer And Rubber Seals: High-toughness engineering plastic retainer ensures low-resistance, low-noise and flexible steel ball circulation. LMK25UU is equipped with premium wear-resistant rubber seals for long-lasting dustproof and anti-fouling protection.
Product Features
Standard square flange structure for quick positioning and secure installation. Ultra-low friction ensures smooth and consistent linear motion. High positioning accuracy and excellent repeatability. Reinforced structure for superior heavy-load capacity. Two structural types adapt to various complex working scenarios.
Application Scenarios
LMK25 square flange linear bearings are widely used in heavy-duty CNC machine tools, large engraving machinery, automatic sliding platforms, industrial robotic arms and automation production lines. LMK25UU is suitable for conventional and dusty environments; LMK25OP is the best choice for high-speed, long-stroke heavy-duty precision automation equipment.
