LMK30 Linear Bearing | LMK30UU / LMK30OP Types Available
The LMK30 linear bearing is a heavy-duty square flange linear motion component for industrial precision equipment. Featuring an integrated square flange for fast, stable mounting, it offers high rigidity, large load capacity and ultra-smooth low-friction movement. Offered in LMK30UU closed type and LMK30OP open type, this bearing provides reliable, cost-effective linear motion solutions for heavy-duty automation machinery.
LMK30UU vs LMK30OP | Model Differences
LMK30UU (Closed Type): Features a full double rubber sealed structure that blocks dust and industrial debris. It preserves internal lubrication to support long-term maintenance-free operation, ideal for standard workshops and dusty working conditions with regular linear strokes.
LMK30OP (Open Type): Designed with an open hollow structure and built-in oil grooves for easy lubrication and fast heat dissipation. It reduces heat accumulation during high-frequency continuous operation, suitable for high-speed, long-stroke and heavy-load precision linear motion applications.
Material Introduction
Bearing Steel Shell And Steel Balls: LMK30 linear bearings adopt high-grade bearing steel with precise heat treatment. High hardness and excellent wear resistance ensure stable heavy-load performance and smooth sliding, extending service life under continuous industrial operation.
Engineering Plastic Retainer And Rubber Seals: High-toughness engineering plastic retainer enables low-noise, low-resistance steel ball circulation. LMK30UU is fitted with durable rubber seals for long-term dustproof and anti-fouling protection.
Product Features
Integrated square flange for accurate positioning and firm installation. Ultra-low friction delivers stable and consistent linear motion. High positioning accuracy and repeatability. Reinforced heavy-load structure for industrial use. Dual types fit different working environments.
Application Scenarios
LMK30 square flange linear bearings are widely used in heavy-duty CNC machine tools, large engraving machinery, automated sliding platforms, industrial robotic arms and automation production lines. LMK30UU works for conventional and dusty environments; LMK30OP is perfect for high-speed, long-stroke heavy-duty precision automation equipment.
