What is a copper alloy bushing/JDB bushing
JDB bushing be composite product made of high-strength brass as the matrix material and embedded with solid lubricant (graphite). Therefore suitable for various composite movements such as relative heavy load, low speed, or linear rotation.
Introduction JDB bushing to raw materials
High strength brass
It is a multi-element wear-resistant and corrosion-resistant aluminum brass with high strength and hardness in copper alloy materials. It does not contain substances or elements such as mercury, cadmium, hexavalent chromium that are toxic or harmful to human health and the environment. At the same time, the lead content is far below the limit of the EU ROHS directive, making it an environmentally friendly metal material. Oil free self-lubricating bearings made of high-strength brass embedded with solid lubricants have been widely used in industries such as machinery, ships, automobiles, molds, and automation equipment around the world.
Graphite
Graphite is an allotrope of carbon, a gray black opaque solid with stable chemical properties, corrosion resistance, and less likely to react with acids, bases, and other chemicals. It can be used as an anti-wear agent, lubricant, and high-purity graphite as a neutron moderator in atomic reactors.
JDB Bushing Product Features
Graphite –
high temperature resistance and hardness
oil-free lubrication/high temperature resistance/thin thickness
Low maintenance frequency, high load-bearing capacity, and strong impact resistance
Thin bushing thickness and compact structural design
Can be used for both linear motion and various composite movements such as rotational motion
Suitable for harsh temperature conditions of high and low temperatures and special environments such as liquids
Graphite Bushing Precautions for use
Temperature range: No refueling: -40 ℃ -200 ℃/Regular refueling -40 ℃ -150 ℃
Before assembly, if lubricating grease can be applied to wipe the friction surface, it can shorten the running in period of the friction pair, make the mechanical operation smoother, and extend the service life
After using the oil-free liner for a period of time, a black or grayish black lubricating film will form on the surface of the shaft. Please do not scrub and use it normally
Generally speaking, materials with higher hardness than oil-free bushings should be selected to protect the shaft
Product types of embedded graphite bushing
Copper alloy straight column JDB bushing
Features: The clearance between the bushing and G6 tolerance guide shaft is small, which can achieve high-precision linear and rotational motion;
Copper alloy straight column JDB bushing with oil groove
Features: Due to the presence of initial running in grease in the oil tank, the frequency of applying grease can be reduced;
Copper alloy thrust bushing/flange JDB bushing
Features: The flange part is embedded with lubricant, so it can withstand both radial and axial loads simultaneously;
Copper alloy guide end flange JDB bushing/middle flange bushing
Features: Suitable for medium to low speed situations and with a flange body size, it can reduce assembly time;
Guide end flange JDB bushing
Features: The oil-free liner will not extend to the opposite side of the installation liner because the space on the opposite side is relatively spacious;
Middle flange JDB bushing
Features: Workpieces can be installed near the center of the oil-free liner body, with good balance on both sides of the flange and dispersed load and space;
Copper alloy gasket
Features: Suitable for relative motion between surfaces, with the advantages of self-lubricating, low friction, and wear resistance; It can achieve similar functions as slide rails, guide rails, and other products, making it more economical.
