LMK50 Linear Bearing | LMK50UU / LMK50OP Types Available
The LMK50 linear bearing is an extra heavy-duty square flange linear motion component for industrial heavy-load equipment. Featuring an integrated square flange for precise positioning and stable mounting, it provides ultra-high rigidity, maximum load capacity and low-friction smooth operation. Available in LMK50UU closed type and LMK50OP open type, this bearing offers durable, cost-effective linear motion solutions for heavy industrial precision automation machinery.
LMK50UU vs LMK50OP | Model Differences
LMK50UU (Closed Type): Features a full double rubber sealing structure with superior dust and contaminant resistance. It locks internal lubrication firmly to enable long-term maintenance-free operation, ideal for standard workshops and harsh dusty industrial environments with regular linear strokes.
LMK50OP (Open Type): Adopts an open hollow structure with built-in oil grooves for convenient lubrication and fast heat dissipation. It eliminates heat accumulation during long-term high-frequency operation, perfect for high-speed, long-stroke and ultra-heavy load precision linear motion applications.
Material Introduction
Bearing Steel Shell And Steel Balls: LMK50 linear bearings adopt high-purity premium bearing steel with professional heat treatment. High surface hardness and excellent wear resistance ensure stable ultra-heavy load performance and ultra-smooth sliding, extending service life under continuous harsh industrial operation.
Engineering Plastic Retainer And Rubber Seals: High-toughness engineering plastic retainer enables low-noise, low-resistance flexible steel ball circulation. LMK50UU is fitted with high-quality wear-resistant rubber seals for long-lasting dustproof and anti-fouling protection.
Product Features
Reinforced square flange design for accurate positioning and sturdy installation. Industrial ultra-heavy load structure with high rigidity. Ultra-low friction ensures consistent and stable linear motion. High positioning accuracy and excellent repeatability. Dual structural types adapt to diverse harsh working scenarios.
Application Scenarios
LMK50 square flange linear bearings are widely used in extra heavy-duty CNC machine tools, large industrial engraving machinery, heavy automated sliding platforms, large industrial robotic arms and industrial automation production lines. LMK50UU suits conventional and dusty environments; LMK50OP is optimal for high-speed, long-stroke ultra-heavy duty precision automation systems.
