Product Description
Product Overview
Round flange self-lubricating linear bearing adopts outer steel shell + inner graphite bronze bushing structure. Compared with traditional ball linear bearings, this oil-free bushing design features high load capacity, low noise, dust resistance and no frequent oil refilling. The integrated round flange with mounting holes enables quick installation and positioning, widely used in automation equipment, CNC machine tools, packaging machinery and textile machinery.
Core Advantages
✅ Self-lubricating Design: Graphite embedded in bronze liner, continuous solid lubrication, long service life, no regular oil supply needed.
✅ High Load & Wear Resistance: Bronze alloy liner supports heavy radial load, excellent wear resistance under reciprocating sliding motion.
✅ Integrated Round Flange: Pre-drilled mounting holes for easy direct installation, accurate positioning, saves assembly time.
✅ Steel Outer Shell: Precision machined steel housing with smooth surface, high rigidity, anti-deformation.
✅ Wide Application: Works in dusty, low-speed, heavy-duty environments where ball bearings fail easily.
✅ Customization Available: Support custom bore size, flange dimension, surface treatment for special machinery requirements.
