Oil-Free Bronze Flange Bushing – Find Immediate Results

Oil-free bronze flange bushing has been developed for high load, low-speed applications and is made of rotational cast high-strength bronze using a specially formed graphite plug as a lubricant.

Our flanged bearings are available in metric and imperial sizes. Our in-house machining service can produce non-standard sizes to suit specific customer requirements.

High Quality Bronze Flange bushing – Expert in Fast Delivery

Bronze flange bushing is commonly used to provide support for a shaft that runs perpendicular to the bearing’s mounting surface. Shafts can create problems when high speeds or heavy loads create shaft flex, vibration, and axial load or movement. This can be eased with the application of a bronze flange bushing that is located in such a way that it supports the shaft.

Application Of self-lubricating graphite flange bushing

This kind of graphite flange bushing can be applied under dry, high temperature, high pressure, corrosive, water, or other chemical environments when no oil can be introduced. It is widely used in automotive product lines, water engineering, dam gate, plastic industries, successive casting machines, steel rollers in the metallurgy industry, mineral machines, ships, turbo generators, hydraulic turbines, and injection molding machines…

Featured Solutions

oil-free graphite flange bushing solutions

  • Low maintenance frequency.
  • It can bear heavier load than a rolling bearing.

  • It can also be used under severe temperature conditions of “high temperature” and “low temperature”.

  • Compared with rolling bearings, the bushing is thinner and saves space.

  • It can be used for linear motion and rotary motion.

Flange bushing as a connection sealing parts, in the production process, if there are quality problems will be leaked, resulting in economic losses, environmental damage, and even safety accidents, so the welding and production of the flange are very important.
At present, the production process of flanges is mainly forging and casting, to understand the two main production processes, to see what is different between them.

flange cast bronze bushings

Forging flange bushing is through the forging machine numerous times pounding, so that the internal structure of the steel becomes tight, so the mechanical properties will be better, the strength will also be high, forging out of the flange bushing is mainly suitable for those with greater pressure in the pipeline.

First of all, the cylindrical billet is cut according to a certain size, heated to a certain temperature so that it becomes thermoplastic, and put on the cold heading machine to let the forging machine constantly pounding billet, so that the internal tightening of the billet, mechanical properties than the original billet is even better.

Also through the punching machine in the billet stamping out the flange bushingabove the round hole, forming the blank flange to be put into the electric furnace for heat treatment to increase the strength of the flange, and finally to cut and polish the flange blank into a flange can be used.

Casting flange bushing has the characteristics of low manufacturing cost and high efficiency, can produce a more complex shape of the flange, casting out of the flange bushing is mainly applicable to those with less pressure in the pipeline.
Casting flange is also a commonly used manufacturing process, is to melt the metal into liquid steel, the steel is poured into the preheated and maintained at a constant temperature in the metal mold to form the shape of the flange bushing, the casting in a period of time after natural cooling molding, and then water to its rapid cooling off the mold, which can also increase the strength of the flange bushing, and finally by polishing and rust-proof treatment can be used.
Flange bushing such small parts, although in the whole product, pipeline or machinery and inconspicuous, but the role played by the flange bushing is very important, the future with the development of flange materials and processes, to ensure that the entire joint connection process more precise and solid, to ensure that people’s use of safe and reliable.
