Professional purchasing each bronze bearing, thin wall bushing, stainless steel bearings, non-standard bearings, and refractory type bearings. A thin-wall embedded self-lubricating bearing comprises a plate; blind holes filled with a solid lubricant are evenly distributed on the working plane of the plate.
Main products: stainless steel bushing, bronze graphite bushing, thin bearings, drawing bearings.
The thin wall bearing realizes the extremely thin bearing section, also realizes the miniaturization, the lightweight product. The variety of products extends its range of USES...
The bronze Bearing from china factory is commonly used in applications requiring a reliable bronze bearing with the added benefit of self-lubrication. The bronze sleeve Bearing self lubricates without oil. For extreme operation conditions, graphite outperforms oil as a bearing lubricating medium.
VIIPLUS's graphing capability can solve any high or low-temperature bearing problem. As well as applications in other hostile environments. graphite bronze Bearings provide a mechanical lubrication system with graphite. They are oil-less and self-lubricating… designed for long life without downtime.

All of our bronze graphite Bearings are made from quality cast bronze. These bearings are machined and plugged with a graphite-based solid lubricant. Bronze Sliding Bearings can be manufactured from a number of bronze alloys to specifically meet your application needs.
What is an oil-free bushing and what are its features?
The liner body is saturated with lubricating oil and can be "used
without oil supply" or "can reduce the number of oil supply"
sliding bearing.
1. Low maintenance frequency;
2. Compared with ball-type linear bearing, the oil-free bushing is
suitable for low-speed heavy-duty applications;
3. It can be used under high and low-temperature conditions;
4, compared with the linear bearing, the liner thickness is thin,
saving space;
5. Can be used for both straight and rotary motion.
What kinds of materials are there for oil-free bushing? What are
their specialties?
VIIPLUS has 5 oil-free liners, copper alloy, bronze casting, dry
casting, resin casting.
Copper alloy (metal), excellent resistance to high temperature,
chemicals, and impact, suitable for heavy and low-speed operation.
Bronze casting (metal), excellent sintering resistance, small
operation, suitable for low load, and high-speed operation.
Dry-type (composite layer), high-temperature resistance, suitable
for heavy load, low-speed operation, thin-wall compact.
Bronze bushings clogged with graphite are all self-lubricating and maintenance-free.
These bushings are made of continuously cast bronze and sealed with fixed lubricating plugs.
A bushing and its mating surface should always be separated by a film of lubricant.
Bronze bushings clogged with graphite do not require additional lubrication
The uses for sockets clogged with graphite are practically unlimited. From hard to maintenance applications to high temperature environments to high load applications, bronze bushings clogged with graphite have excellent durability and wear resistance.
Such applications include: Steel Mills, Furnace dragouts, Drying Equipment, Roasters, Heat Exchangers, Press dies, Assembly lines, Machine tools, Chain Conveyors, Off shore structures, Deck cranes,Winches, Hatch covers, Rudder arms, Hoisting equipment, Tire & Paper Mills, Toggle link bearings for injection mold machinery, Mixers, Grinders, Pulverizers, Construction machinery, Mining rigs, Arm link bearings, Power shovels, and more.
