LM30 Linear Bearing | LM30UU / LM30OP Types Available
The LM30 linear bearing is a heavy-duty high-precision linear motion component designed for low-friction sliding and stable linear movement. It offers strong load capacity, high positioning accuracy and reliable high-speed performance, ideal for medium and heavy industrial automation machinery. Available in LM30UU closed type and LM30OP open type, this bearing provides durable, cost-effective linear motion solutions for industrial mechanical and automation systems.
LM30UU vs LM30OP | Model Differences
LM30UU (Closed Type): Comes with a fully closed double rubber sealing structure for full dustproof protection. It effectively blocks dust, debris and contaminants and retains internal lubrication, enabling long-term maintenance-free operation. It works best for standard workshops and dusty industrial environments with regular linear strokes.
LM30OP (Open Type): Features an open hollow structure with built-in oil grooves for easy lubrication and fast heat dissipation. It reduces heat accumulation during continuous high-frequency operation, perfectly suited for long-stroke, high-speed and heavy-load linear motion applications.
Material Introduction
Bearing Steel Shell & Steel Balls: LM30 linear bearings adopt high-quality bearing steel with professional heat treatment. High hardness and excellent wear resistance ensure stable load-bearing performance and ultra-smooth sliding, supporting long service life under continuous heavy operation.
Engineering Plastic Retainer & Rubber Seals: High-toughness engineering plastic retainer ensures flexible steel ball circulation with low noise and low running resistance. LM30UU uses wear-resistant rubber seals for stable dustproof and anti-fouling performance.
Product Features
Ultra-low friction for smooth linear motion. High positioning accuracy and stable movement repeatability. Dual structural designs fit various speed and load conditions. Reliable heat dissipation and dustproof capability. Standard size for easy installation and replacement.
Application Scenarios
LM30 linear bearings are widely used in CNC machine tools, heavy automation sliding platforms, industrial robotic arms, large packaging machinery and automation production lines. LM30UU is suitable for conventional and dusty working environments; LM30OP is ideal for high-speed, long-stroke and high-precision heavy-duty automation equipment.
