Product Description
Overview
This round flange self-lubricating linear bushing adopts outer steel shell + inner graphite embedded bronze bushing structure, replacing traditional ball linear bearings. The graphite solid lubricant is pre-embedded in the high-strength bronze matrix, which can continuously supply lubrication during reciprocating linear movement. No frequent oil refueling required, suitable for high-load, low-speed, dusty and oil-prohibited working environments. The integrated round flange design with mounting holes enables fast and stable installation directly on equipment plates. It is widely used in CNC machines, automation machinery, packaging & textile equipment, injection molds and robotic linear sliding systems.
Key Features
✅ Self-lubricating Performance: Embedded graphite lubricant, maintenance-free, no oil supply needed in long-term operation
✅ High Load & Wear Resistance: High strength bronze alloy liner, withstand heavy radial load, long service life
✅ Outer Steel Housing: Precision machined steel outer shell, good rigidity, anti-deformation
✅ Round Flange Mounting: Pre-drilled mounting holes for simple alignment and fast assembly
✅ Wide Application: Workable in dusty, high temperature, oil forbidden, reciprocating motion scenarios
✅ Custom Available: Multiple standard sizes in stock, OEM & ODM custom machining supported
