LMH30 Linear Bearing | LMH30UU / LMH30OP Types Available
The LMH30 linear bearing is a heavy-duty extended flange-type linear motion component. Designed with a lengthened body and integrated flange, it delivers high rigidity, large load capacity and stable linear movement. Available in LMH30UU closed type and LMH30OP open type, this bearing offers durable and cost-effective linear motion solutions for heavy-duty industrial and precision automation systems.
LMH30UU vs LMH30OP | Model Differences
LMH30UU (Closed Type): Features a fully closed double rubber sealing structure for excellent dust and contaminant resistance. It retains internal grease steadily and supports long-term maintenance-free operation, suitable for standard workshops and dusty industrial environments with regular linear stroke operation.
LMH30OP (Open Type): Adopts an open hollow structure with built-in oil grooves for easy lubrication and efficient heat dissipation. It reduces thermal 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: LMH30 linear bearings adopt high-grade bearing steel with professional heat treatment. High hardness and superior wear resistance ensure stable heavy-load performance and ultra-smooth sliding, extending service life under continuous industrial operation.
Engineering Plastic Retainer And Rubber Seals: High-toughness engineering plastic retainer ensures flexible and low-noise steel ball circulation with low running resistance. LMH30UU is fitted with wear-resistant rubber seals for reliable long-term dustproof and anti-fouling protection.
Product Features
Extended body design for higher rigidity and stronger load capacity. Integrated flange for quick and firm installation. Ultra-low friction for smooth and stable linear motion. High positioning accuracy and excellent repeatability. Dual structural designs adapt to diverse heavy-duty working conditions.
Application Scenarios
LMH30 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. LMH30UU is suitable for conventional and dusty working environments; LMH30OP is ideal for high-speed, long-stroke heavy-duty precision automation equipment.
