LMH40 Linear Bearing | LMH40UU / LMH40OP Types Available
The LMH40 linear bearing is a large heavy-duty extended flange linear bearing. Featuring a lengthened body and integrated flange structure, it offers higher rigidity and larger load capacity than standard flange bearings. Available in LMH40UU closed type and LMH40OP open type, it provides stable, cost-effective linear motion solutions for heavy-duty industrial automation machinery.
LMH40UU vs LMH40OP | Model Differences
LMH40UU (Closed Type): Adopts double rubber fully sealed structure to block dust, debris and contaminants. It locks internal lubrication to achieve long-term maintenance-free operation, suitable for standard workshops and dusty working conditions with regular linear strokes.
LMH40OP (Open Type): Designed with open hollow structure and built-in oil grooves for easy lubrication and efficient heat dissipation. It avoids heat accumulation during high-frequency continuous operation, ideal for long-stroke, high-speed and heavy-load precision linear motion applications.
Material Introduction
Bearing Steel Shell And Steel Balls: LMH40 linear bearings use high-grade bearing steel with precise heat treatment. High hardness and excellent wear resistance ensure stable heavy-load performance and ultra-smooth sliding for long-term continuous operation.
Engineering Plastic Retainer And Rubber Seals: High-toughness plastic retainer ensures low-noise and low-resistance steel ball circulation. LMH40UU is equipped with wear-resistant rubber seals for durable dustproof and anti-fouling protection in industrial environments.
Product Features
Extended body for higher rigidity and heavy load capacity. Integrated flange for fast and firm installation. Ultra-low friction for smooth and stable linear motion. High positioning accuracy and repeatability. Dual structural designs adapt to multiple heavy-duty working scenarios.
Application Scenarios
LMH40 extended flange linear bearings are widely used in heavy-duty CNC machine tools, large engraving machinery, automated sliding platforms, industrial robotic arms and automation production lines. LMH40UU applies to conventional and dusty environments; LMH40OP fits high-speed, long-stroke heavy-duty precision automation equipment.
