Introduce the application of oil-free bushings, what is the use of cooperation?

Looping effect
In the field of valve applications, the bushing is enclosed in the valve cover and the valve stem is wrapped. Generally, the DU oil-free bushing uses corrosion resistance data such as PTFE or connecting rod bushing graphite for sealing effect.
make up
Effect: protect the shaft, seat hole, no DX oil-free bushing wear; shock absorption, noise reduction; reduce stainless steel coiled bushing to reduce disassembly and repair;
Information: An imported THORPLAS can be considered;
Application: no oil-free composite bushing grease, dry work;
Device: Interoperability cooperation
Oil-free bushing, no need to add smooth oil JDB graphite copper sleeve and smooth grease, convenient in operation and protection, saving cost, time and cost;
There are several types:
There are many in the mall now, there are three main types:
1, metal matrix, generally copper lead, the appearance of holes, the hole to participate in smooth grease; relying on a lot of smooth grease support work in the hole, in fact, long-term need also refueling;
2, composite bushing, one is steel back + copper powder + PTFE Teflon, the other one is steel back + copper powder + POM polyoxymethylene; attributed to limited molding; work by bushing inner wall data, but Very thin, brittle, unacceptable when pressure is high;
3, non-metallic self-smooth bushing: true self-smooth; nylon, PTFE, and Sailong
The oil-free bushing says that the white is the improvement of the copper sleeve. At the time of design, if the light load, we will choose the copper sleeve and the oil-free bushing.
Most oil-free bushings today are steel plates, center-spun spherical bronze powder, and other materials such as polytetrafluoroethylene (PTFE) and lead. The friction coefficient is small, the wear resistance is good and the oil is not smooth. It is mostly used for sliding parts of various machinery, such as printing machines, textile machines, and exercise equipment hydraulic pallet trucks. Some bushings are handled by special processes and can accept high-speed motion, but cannot accept heavy loads.
Hunan Jintai Hardware and Machinery Co.,Ltd. is a professional manufacturer on various kind of bearings over 15 years China factory.
We are making all kinds of slide bearings including JF bimetal bearing,DU PTFE composit bushing, DX POM composite bushing,wrapped bronze bushing, cast sliding bushings and wear plate bearing pad, sintered bronze bushing and sintering parts, ball transfer bearings, etc.
The shapes of bearings can be in sleeve, flanged, spherical, plate, washer, pad, ring, square etc.
Base materials in carbon steel, harden steel, iron, stainless steel, bronze, brass, copper, bronze-steel alloy.Lubricant materials in PTFE, teflon, POM, nylon, plastic, oil, graphite, grease, MoS2, etc.
