Flanged Type Oilless Bronze Bearing Graphite Embedded Brass Bushing, Self Lubricating Flange Copper Sleeve for Automation, Molds, Hydraulic Equipment
Product Description
This flanged graphite embedded bronze bushing is an oilless self-lubricating bearing made of high-strength cast bronze, with solid graphite plugs embedded on the sliding surface. The flange design with mounting holes enables easy installation and axial positioning.
No oil refueling required during operation, suitable for high load, low speed, intermittent motion and oil-free working conditions. It features excellent wear resistance, high compressive strength, good thermal conductivity and stable performance under shock load. Widely applied in injection molds, automation equipment, hydraulic cylinders, textile machinery, construction machinery and other industrial fields.
