Embedded Round Flange Linear Bearing, Bronze Graphite Insert Bushing, Maintenance-free Linear Motion Bushing

Product Overview

Round flange linear bearing is an embedded flanged linear sliding bushing with outer steel shell and inner graphite bronze alloy liner. It adopts solid graphite embedded self-lubricating technology, replacing traditional ball linear bearings. No continuous oil supply required, greatly reducing maintenance work. The circular flange with mounting holes enables fast installation and positioning directly onto equipment frames. It features high load capacity, low friction, excellent wear resistance and shock resistance, suitable for dusty, high-temperature, oil-forbidden working environments widely in automation, CNC machinery, textile and packaging equipment.

Main Features

✅ Self-lubricating Design: Graphite solid lubricant embedded in bronze liner, maintenance-free, no frequent grease refilling.

✅ High Load & Wear Resistance: High strength bronze alloy liner, withstand static & impact load better than ball linear bearings.

✅ Stable Operation: Low friction coefficient, smooth linear movement, low noise during reciprocating motion.

✅ Easy Assembly: Integrated round flange with 4 mounting holes, quick bolt fixing, accurate positioning.

✅ Wide Application: Adapt to high dust, high temperature, water splash environments; corrosion-resistant steel shell optional.

✅ Custom Available: Custom bore size, flange dimension, stainless steel housing, special surface treatment on request.

Application Scenarios

• CNC machine tools, automation linear sliding modules
• Robotic equipment, handling machinery
• Packaging, printing & textile machines
• Hydraulic machinery, injection mold auxiliary guide
• Medical equipment, food machinery (oil prohibited environment)
