LMF20 Linear Bearing | LMF20UU / LMF20OP Types Available
The LMF20 linear bearing is a heavy-duty flange-type high-precision linear motion component. Featuring an integrated flange for direct, stable installation, it delivers low-friction sliding, large load capacity and consistent high-speed stability. Available in LMF20UU closed type and LMF20OP open type, this bearing provides durable, cost-effective linear motion solutions for medium and heavy industrial precision automation equipment.
LMF20UU vs LMF20OP | Model Differences
LMF20UU (Closed Type): Features a fully closed double rubber sealing structure with complete dust and contamination protection. It firmly locks internal lubrication, enables long-term maintenance-free operation, and fits standard workshops and dusty industrial environments with regular linear stroke operation.
LMF20OP (Open Type): Adopts an open hollow structure with built-in oil grooves for convenient lubrication and efficient heat dissipation. It effectively reduces thermal accumulation during high-frequency continuous movement, ideal for long-stroke, high-speed and high-precision heavy-load linear motion applications.
Material Introduction
Bearing Steel Shell And Steel Balls: LMF20 linear bearings adopt premium bearing steel with professional heat treatment. High surface hardness and excellent wear resistance ensure stable heavy-load capacity and ultra-smooth sliding, extending service life under continuous long-term operation.
Engineering Plastic Retainer And Rubber Seals: High-toughness engineering plastic retainer ensures flexible steel ball circulation with low noise and low running resistance. LMF20UU is equipped with wear-resistant rubber seals for reliable dustproof and anti-fouling performance.
Product Features
Integrated flange design for fast and firm mounting. Ultra-low friction for smooth and stable linear motion. High positioning accuracy and excellent motion repeatability. Dual structural designs adapt to diverse working conditions. Standard industrial size with stable heavy-duty performance.
Application Scenarios
LMF20 flange linear bearings are widely used in CNC machine tools, heavy-duty engraving equipment, automated sliding platforms, industrial robotic arms and large automation machinery. LMF20UU is suitable for conventional and dusty industrial environments; LMF20OP is perfect for high-speed, long-stroke precision heavy-duty automation scenarios.
