Product Introduction

JDB650 self-lubricating brass bushing oil-free bearing adopts special composite material and embedded solid lubricant, which can operate stably for a long time without external lubrication. It is suitable for low speed and high load, high temperature or harsh working environment, and is widely used in machinery and equipment that require self-lubricating system.

Main parameters
Material: Brass alloy (Brass) + solid lubricant
Operating temperature range: -40°C to +300°C (some applications can reach +350°C)
Maximum load: 30-50 MPa (depending on working conditions)
Friction coefficient: usually 0.1-0.2, depending on load and speed
Maximum sliding speed: 2-3 m/s
Hardness: > 100 HB (Brinell hardness)
Corrosion resistance: good, suitable for humid and mildly corrosive environments
Working environment: dry, oil-free or low-speed operation environment

Main features
Self-lubricating: JDB650 bearings are embedded with solid lubricants, which can run for a long time without oil, reducing dependence on external lubrication.
Wear resistance: It has strong wear resistance and is suitable for high-load and low-speed working conditions.
Corrosion resistance: It has excellent corrosion resistance and is suitable for use in a variety of chemical environments.
High temperature resistance: It can withstand high temperature working conditions and is suitable for use in high temperature or thermal expansion environments.
Reduced maintenance: Due to its self-lubricating properties, it reduces the need for regular lubrication and maintenance, saving maintenance costs.

Application scope and scenarios
Industrial equipment: It is suitable for various types of mechanical equipment, such as transmission devices, conveyor belt systems and automated production lines.
Automotive industry: It is widely used in parts that require high-load operation, such as automobile engines, gearboxes, and brake systems.
Agricultural machinery: It is used in agricultural machinery and equipment, especially in environments where external lubricants are not suitable.
Power equipment: It is suitable for bearing systems in wind turbines and power generation equipment. Its high temperature resistance and corrosion resistance make it perform well in harsh environments.
Engineering machinery: For heavy machinery such as excavators and bulldozers, JDB650 can effectively reduce friction and wear and extend equipment life.
