JDB-600 Casting Bronze Bearing: Unrivaled Durability for Heavy - Duty Machinery Applications

JDB-600 Casting Bronze Bearing is a high-performance cast bronze bearing that stands out in the field of heavy-duty machinery for its excellent durability and reliability.

JDB-600 Casting Bronze Bearing

1. Material properties
• Material composition: The main material of JDB-600 is high-strength brass (ZCuZn25Al6Fe3Mn4). This material has twice the hardness and wear resistance of ordinary tin bronze, and has higher tensile strength and yield strength.

• Performance indicators:

• Density: 8.0 g/cm³.

• Hardness: >210 HB.

• Tensile strength: >750 N/mm².

• Yield strength: >450 N/mm².

• Elongation: >12%.

• Lubrication performance: The surface of JDB-600 is designed with a pre-lubricated film, which can quickly form an effective solid lubricating film under dry friction conditions to reduce wear.

2. Application Fields
JDB-600 Casting Bronze Bearing is widely used in various heavy machinery and equipment, and can withstand high loads and extreme working conditions:

• Engineering machinery: used for track roller bushings, traction wheel bushings, tensioner bushings, etc. of chassis walking mechanisms.

• Automobile industry: suitable for balance shaft bushings, steel plate pin bushings, steering knuckle kingpin bushings, connecting rod bushings, valve rocker arm bushings, camshaft bushings, differential bushings, gearbox bushings, internal combustion engine main bearings, thrust washers, etc.

• Mining machinery: In the joints of excavators and large gearboxes, JDB-600 can withstand high loads and extend the life of equipment.

• Injection molding machinery: JDB-600 bearings perform well in injection molding machines and can meet the requirements of high precision and high loads.

• Ships: Due to its corrosion resistance and wear resistance, JDB-600 bearings are widely used in ship propulsion systems and steering gear systems.

• Metallurgical machinery: In metallurgical machinery such as continuous casting mills and steel rolling equipment, JDB-600 bearings can withstand high temperatures and high loads.

3. Advantages
• High load capacity: JDB-600 bearings can withstand extremely high static and dynamic loads.
• Low friction coefficient: It has a very low and stable friction coefficient and no "sticking" phenomenon.
• Maintenance-free design: It can run for a long time without maintenance.
• Corrosion and wear resistance: The chemical stability of the material makes it perform well in harsh environments.
• Wide range of application: It can be used in a wide temperature range (-40℃ to +300℃).
