HIGH QUALITY OILLESS BEARING

Large Diameter Bronze Bearings, Standard Metric Flange Bushings

Plain Bearing Bushes: We use the term “Oversized” or “Large Diameter” for any bearing requring 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.

What Is A Large Bearing?

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

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 is suitable for all kinds of large and heavy machinery and is an important component of the machinery. It has high hardness, excellent wear resistance, is not easy to cause seizure, has good casting performance and cutting performance, and has good corrosion resistance in the atmosphere and fresh water.

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.

Corrosive

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.
