LMH20 Linear Bearing | LMH20UU / LMH20OP Types Available
The LMH20 linear bearing is a heavy-duty extended flange-type linear motion component. Featuring a lengthened body and integrated flange design, it provides higher rigidity, larger load capacity and more stable operation than standard linear bearings. Available in LMH20UU closed type and LMH20OP open type, this bearing delivers durable and cost-effective linear motion solutions for medium and heavy precision automation equipment.
LMH20UU vs LMH20OP | Model Differences
LMH20UU (Closed Type): Equipped with a fully closed double rubber sealing structure for excellent dust and contaminant protection. It effectively retains internal lubrication and supports long-term maintenance-free operation, suitable for standard workshops and dusty industrial working conditions with regular linear strokes.
LMH20OP (Open Type): Adopts an open hollow structure with built-in oil grooves for easy lubrication and efficient heat dissipation. It minimizes 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: LMH20 linear bearings adopt premium bearing steel with professional heat treatment. High surface hardness and superior wear resistance ensure stable heavy-load performance and ultra-smooth sliding, extending service life under continuous long-term operation.
Engineering Plastic Retainer And Rubber Seals: High-toughness engineering plastic retainer enables flexible, low-noise steel ball circulation with low running resistance. LMH20UU 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 improved load capacity. Integrated flange for quick and sturdy installation. Ultra-low friction ensures smooth and stable linear motion. High positioning accuracy and excellent repeatability. Dual structural designs adapt to diverse heavy-duty working scenarios.
Application Scenarios
LMH20 extended flange linear bearings are widely used in CNC machine tools, heavy-duty engraving equipment, automatic sliding platforms, industrial robotic arms and automation production lines. LMH20UU suits conventional and dusty industrial environments; LMH20OP is perfect for high-speed, long-stroke heavy-duty precision automation systems.
