LM80 Linear Bearing | LM80UU / LM80OP Types Available
The LM80 linear bearing is a large-size heavy-duty linear motion component engineered for low-friction, stable linear sliding. Featuring ultra-high load capacity, precise positioning and durable high-speed performance, it is widely adopted in heavy industrial machinery and automation systems. Available in LM80UU closed type and LM80OP open type, this bearing offers reliable, cost-effective linear motion solutions for heavy-load industrial applications.
LM80UU vs LM80OP | Model Differences
LM80UU (Closed Type): Designed with fully closed double rubber seals for full dust and contaminant isolation. It effectively retains internal lubrication and supports long-term maintenance-free operation, ideal for standard workshops and dusty industrial environments with regular linear stroke movement.
LM80OP (Open Type): Features an open hollow structure with preset oil grooves for convenient lubrication and efficient heat dissipation. It reduces thermal accumulation during high-frequency continuous operation, perfectly suitable for long-stroke, high-speed and ultra-heavy load linear motion working conditions.
Material Introduction
Bearing Steel Shell & Steel Balls: LM80 linear bearings adopt premium bearing steel with professional heat treatment. High surface hardness and excellent wear resistance deliver stable heavy-load performance and ultra-smooth sliding, extending service life under continuous heavy-duty operation.
Engineering Plastic Retainer & Rubber Seals: High-toughness engineering plastic retainer enables flexible steel ball circulation with low noise and low running resistance. LM80UU is equipped with durable rubber seals for stable dustproof and anti-fouling protection.
Product Features
Ultra-low friction for smooth and stable linear motion. High positioning accuracy and excellent movement repeatability. Dual structural designs adapt to diverse heavy-duty working demands. Reliable heat dissipation and dustproof performance. Standard size for simple installation and replacement.
Application Scenarios
LM80 linear bearings are widely used in large CNC machine tools, heavy-duty automation platforms, industrial robotic arms, large packaging machinery and automated production lines. LM80UU fits conventional and dusty industrial environments; LM80OP is ideal for high-speed, long-stroke and high-precision heavy-duty automation equipment.
