Large Diameter Bronze Bearings, Standard Metric Flange Bushings

Plain Bearing Bushes: We use the term “Oversized” or “Large Diameter” for any bearing requiring an outside diameter exceeding our largest “off the shelf” size, generally 20 inches. To meet the larger diameter requirements we offer customized solutions including either the centrifugal or static cast process.

Large Tin Bronze Bushings

Tin bronze is a bronze with tin as the main alloying element. The tin content is generally between 3 and 14% and is mainly used to make elastic components and wear-resistant parts.
As it is a non-ferrous alloy with minimal casting shrinkage, it can be used to produce castings with complex shapes, clear contours, and low airtightness requirements. It is very resistant to corrosion in the atmosphere, seawater, freshwater, and steam and is widely used for steam boilers and marine parts.

The Application Of Large Diameter Bronze Bushing

Large bronze bushings are the secret to withstanding large loads and high pressures. Our Large casting bronze bushings are an important part of all kinds of heavy and large machinery that play an important role. including Heavy Duty Construction Equipment, Hydro-Electric, Offshore Marine, Nuclear, and Machine Repair.

Large Bronze Bushing Used In Marine

In order to meet the requirements of modern ships, to ensure that large bronze cast bushings can work reliably under various navigational conditions and harsh environments: 1. need sufficient strength and stiffness 2. adaptable to hull deformation
3. Good sealing, lubrication, and cooling; easy management and maintenance

What Is A Large Bearing?

Bearings with an outer diameter greater than 440mm are collectively called oversize bearings. In large machinery, especially construction machinery, oversize bearings are increasingly widely used.

Large bronze bushings in alloys such as aluminum brass, tin bronze, aluminum bronze, and zinc-based alloys are produced according to customer requirements. we also can produce according to your requirements in the form of drawings.

Large Bronze Bushings – Marine Bearing

Due to the strong sensitivity of tin bronze to porosity, for small and medium-sized tin bronze stern bushings there is the use of graphite-embedded bronze bushing. This type of thermal conductivity is very good, the large cooling effect is convenient for processing and manufacturing, High density of castings. Marine Bearing has excellent vibration damping, wear resistance, self-lubricating, and has the good load-bearing capacity, dimensional stability & deflection adjustment, while no additional lubricant is required, and can work underwater for long periods.

Large Diameter Bronze Bushing Design

Due to the particularity of extra-large bearings (high speed, heavy load, etc.), the general design method is not completely suitable for the design of extra-large bearings. If the ordinary bearing design theory method is used for calculation, the calculation parameters are determined according to the design experience. The design experience and randomness are very large, and it is difficult to ensure the design quality.
The new design method of VIIPLUS digs the effective space of bearing design greatly improves the objective function of bearing design, increases the rated dynamic load of the bearing, and thus greatly improves the rated life value.

High Performance Large Copper Sleeve

The large copper sleeve adopts fine quality copper in conformity with international standards as raw material from leakage. The material contains no toxic impurities and complies with green health requirements,

Sliding bushings are a separate type of plain bearing used to prevent friction. They are cylindrical bushings used inside a shaft, pin, or hinge to prevent wear in the bore. Sliding bushings are inserted into the housing to provide a bearing surface for rotating applications.

Another feature of copper bushings is the corrosion resistance and excellent corrosion performance. It is mainly used in the atmosphere and freshwater because this environment is still relatively good. In the process of using copper bushings, it is usually not easy to appear seized. The corrosion resistance of the copper bushing is mainly reflected in the large copper bushing of the excavator’s arm on some chemical elements. Its performance is relatively good. Even if there is no lubricant and water quality lubricant, it can still work normally. The performance and self-lubricating function can still be maintained.

Abrasion resistance

The wear resistance of large copper sleeves is still the best, and equipment with different materials has different characteristics. The internal arrangement of the parts of the copper bushing is still closely contrasted, and it will not present a too loose scene. It has no air holes and trachoma, so the copper bushing is still brightly contrasted from the outside, and its color contrast is special. And most importantly, its hardness is relatively high.

Ability to withstand pressure

The compressive capacity of the large copper bushing is also relatively good. Its surface pressure is very large. The flange-integrated oil-free bushing can perfectly accept the side pressure of the bearing. The copper bushing can also operate under high load pressure. It is suitable for occasions where low speed and heavy load are used.

Plain Bearings & Bushes

manufactures bushings in various designs and from different materials.

Our large diameter bronze bushings products are suitable for even the toughest conditions. Whether you need bronze bearings in water, under high temperatures or in extremely dirty areas – we are at your side with your projects right up to finalization!

  • Our experience ranges from port and shipping areas, independent of fresh or salt water, to foundries and waste incineration plants.

  • Our large diameter bronze bushes and big size bronze plates can also be manufactured in your intermediate sizes. We can also manufacture the special size to decimal place.

Bronze bushes are available as a standard product

With inside diameters of up to 100 mm or 300 mm depending on the material.
