RB - Bonomi

Pins and Bushings

Pins and Bushings are very important parts for a good functioning of the joints of arms and buckets of excavators and earth moving machines.

 

When these vital pieces degrade and wear out after a long usage or because a bad lubrication, you can see a worsening in both the performance and the quality of work and an overall decline in the machines productivity and efficiency.

 

RB Bonomi pins and bushes are produced with best material and treatments to guarantee  equal performaces of original spare parts. Opting for a lower quality aftermarket part could result a very bad choice.

Therefore you should consider investing in the best aftermarket option for your machine, and RB Bonomi represents it, in order to avoid having to replace pins and bushes sooner than it is necessary.

 

We have over 5,000 types of bushings and 2,000 pins on stock. Our spare parts are suitable for Komatsu, Caterpillar, JCB, Volvo, Yanmar, Kubota, Takeuchi, Hitachi, Case, New Holland, Kobelco, Wacker Neuson, Doosan and Ihimer machines (small or big ones) to only mention a few.

 

We have also cataloged our pins and bushings in order to respond to your requests as quickly and effectively as possible: you can provide us with the code, the size or simply indicate the model of your machine.

Pins

Fields of application of R.B. pins: excavators, mini excavators, track and wheel loaders, bulldozers, backhoe loaders, dumpers, dozers, graders and other earth moving machines.

 

Our pins have a diameter from ø16mm up to ø130mm, and are made of steel 42CrMo4 (with a 58-62 HRC up to 5mm induction hardening.) These are long-lasting and high-performance products.

 

We also have pins deriving from phosphate coating as well as from galvanisation. Here are some types of them: dowel holes, grease holes, extractor holes, seeger, central undercuts, edges, flanges (collars,) millings and threads.

 

We can manufacture custom pins quickly and, in any amount, (even a single one!) all you need to do is show us a drawing or a sample.

Bushings

Fields of application of R.B. bushings: excavators, mini excavators, earthmoving machinery, agricultural machinery, drilling machinery and various equipment.

 

We have different kinds of steel bushings and bronze bushings on stock: hardened steel bushings, outer and inner tension bushings, bronze bushings, sliding bushings, bimetallic bushings and plastic bushings.

 

Our bushings are quite peculiar and versatile, thus they are suitable for earth moving machines, agricultural machines (harrows, ploughs, backhoes,) drilling rigs, and other equipment such as polyp grabs, buckets and log grabs.

 

Each bushing comes in different types and sizes: from a ø16mm up to over ø250mm.
