There are many types of bushings. These include sleeve, flanged, spherical, rubber, and custom bushings. Each type is made for a special job or load.
Bushings can be made from bronze, steel, brass, plastic, rubber, or composites. The material changes how bushings work in different places and uses.
Picking the right bushing depends on load, speed, environment, and how much care it needs. This helps bushings last longer and saves money.
Taking care of bushings and changing them on time keeps machines working well. It also lowers repairs and makes things safer in jobs like construction, cars, and mining.
Bushings are very important in machines. They help lower friction and support heavy things. They also help machines last longer. There are many types of bushings. Each type has a special job in factories and on building sites.
The main types are:
Sleeve bushings: These are round and help parts slide. They also hold up weight from the side.
Flanged bushings: These look like sleeve bushings but have a rim. The rim keeps them in place and makes them stable.
Spherical bushings: These let parts move at angles. They help when parts do not line up right.
Rubber bushings: These soak up shakes and bumps. They also make machines quieter.
Custom bushings: These are made for special jobs. They are used in big machines like those in mines or on building sites.
Some bushings are made for special uses. These include grooved bushings, thrust washers, carbon graphite bushings, and self-lubricating bushings. These bushings help machines work better and last longer in tough places.
Tip: Picking the right bushing helps machines work well. It also means you do not have to fix them as often.
Sleeve bushings are also called plain bushings. They are the most common kind in big machines. They help with side loads and let parts move smoothly.
Grooved bushings are a kind of sleeve bushing. They have grooves or holes to hold oil. This lowers friction and helps them last longer.
Some bushings are made from hard steel. These are strong and do not wear out fast. They are good for heavy work.
Machines like excavators and loaders use sleeve bushings in many places. These include pivot points, axles, steering joints, and hydraulic cylinders. Sleeve bushings keep these parts from wearing out too soon. They help machines work well.
Flanged bushings have a rim at one end. The rim stops them from moving sideways. It also keeps them in the right spot.
This shape lets flanged bushings hold both side and end loads. That is why they are used in loaders and excavators.
The rim makes the connection stronger. It also helps the bushing hold more weight, especially at hinges and joints.
Some flanged bushings have grooves. These grooves help oil spread and lower the need for repairs in big machines.
Spherical bushings have a ball-shaped inside. This lets them turn at angles.
They spread weight over a bigger area. This makes them strong and long-lasting.
Machines with moving joints, like excavators and cranes, use spherical bushings. These bushings help send power and stop parts from bending.
Spherical bushings are better than rubber bushings for heavy loads. They also keep joints steady.
Rubber bushings are stretchy and strong. They soak up shakes and bumps.
They act like cushions and keep parts apart. This makes machines quieter.
There are different shapes, like solid, hollow, flange, and sleeve. The shape changes how well they stop shaking.
Rubber bushings are used in engine mounts, suspension, and big machines. They protect parts and make machines more comfortable to use.
Some rubber bushings have grooves. These grooves help them stop shaking even better and last longer.
Custom bushings are made for special needs in mining, building, and factories.
Companies like Shanghai Fenghua International Enterprise Co., Ltd. work with customers. They help pick the best materials and shapes for each job.
Custom bushings can be plain, flanged, spherical, tapered, split, self-lubricating, or composite.
They are made with care so they work well in tough places.
For example, some custom grooved bushings are made from strong metals. These last a long time and help mining machines work without stopping.

Bronze bushings sometimes get special coatings like graphite spray. These coatings help them slide better and last longer. Heat treatments can make them even harder and less likely to bend. Bronze can take high heat and does not rust easily. This is why it is used in tough places.
Bronze bushings last longer and hold more weight than plastic ones. This makes them a smart pick for big machines.
Steel bushings are used a lot in heavy machines. There are hardened steel bushings and stainless steel bushings. Steel is very strong and can hold a lot of weight. These bushings are found in building machines, mining tools, and tools that need to be exact.
Steel bushings get stronger with heat treatments:
Carburizing puts more carbon on the outside to make it harder.
Quenching and tempering make it hard but not too brittle.
Nitriding adds nitrogen to make the surface even tougher.
Coatings like galvanizing and chrome plating help stop rust and lower friction. These changes make steel bushings good for heavy loads, high heat, and places where things might rust.
Steel bushings are best for machines like excavators and loaders.
Hardened steel bushings last longer at joints and pivot spots.
Stainless steel bushings work well in wet or chemical places.
Heat treatments and coatings help steel bushings last longer in factories.
Brass bushings are good because they do not rust and slide easily. Brass is made from copper and zinc. It does not rust, so it is used in boats and mines. Some types like CuAl10Ni and RG7 are even better at fighting rust and wear.
Brass bushings work well in salty water, chemicals, or outside.
Adding graphite to brass makes it even better at sliding and not rusting.
Grades like H59, H62, and H65 are picked for their strength.
Brass bushings are often used in pumps, valves, and boat parts. These places often get wet or have chemicals.
Plastic bushings are made from special plastics like nylon, PTFE, POM, and PEEK. They are light, slide well, and do not wear out fast. These bushings are best for fast-moving, light jobs where you do not want to do much upkeep.
Plastic bushings give:
Self-lubrication, so you do not need oil.
They do not rust and keep their shape.
They are quiet and help stop shaking.
Plastic bushings can move fast and still work well. They are used in cars, planes, and machines where weight and easy care matter.
Rubber bushings soak up shakes and noise. They act like soft pads between moving parts. They are used in engine mounts, car suspensions, and big machines to protect parts and make them smoother to use.
Rubber Type | Temperature Range | Chemical Resistance Highlights |
