4 main  mechanical parts ranges in diameters from 10 mm to 300 mm in steel, stainless steel or bronze, with one or more layers in metallic alloys (with copper, tin, Aluminium, nickel... basis elements) or synthetic layers as PTFE for the PYDANE ® Bushings  realised in strict respect of even the smallest tolerances.

SLIDING BUSHINGS : Cylindrical opened or closed bushings.
The open rolled sliding bushings, with or without joint, result from a rolling and shaping process on steel + sinterbronze sheets. These sliding sleeves can also be closed by laser welding or stapling. 
However they have high mechanical and dynamic characteristics. All bushings may be realised with one or two flanges.

On closed sliding bushings, the layers in bronze or tin are applied during a smelting process.

Opened PYDANE (R) Bushings : specifically realised from a 316 TI Stainless Steel backing covered by smelting with a metal / PTFE fabric.

BIMETAL BEARINGS : CBP is specialised in thin antifriciton bearings and notably connecting rod bushings and engine bearings with or without flanges.
CBP bimetal bearings are manufactured through two distinct types of production : either from a steel backing with a sinterbronze layer or from a steel backing plus white metal layer. Supplementary layers made from lead or nickel may complete the products characteristics.

SLIDING THRUST WASHERS : Thanks to its means of production covering a wide range of processes, CBP ensures the production of thrust washers, semi-thrust washers, in steel & bronze or steel and white alloy, in high resistance nickel copper or even in steel or metal with loaded PTFE. The search for precision, throughout decades, allowed the implementation of production processes which could meet the requirements of the most demanding customers. Many flat or spherical thrust washers with very tight tolerances are produced each month. They are involved in the production of engines, pumps, compressors, and special machines for guiding mobile parts. They can also be found in transmissions as sliding thrust washers for wheels in railways, in sliding kinematics for differentials of 4x4, 4x6, lorries and transhipment vehicles or also in gearboxes.

SLIDING GUIDES : These sliding guides resulting either from plates obtained through the sintering production processes developed by CBP or from the PYDANE (R) production line. They facilitate linear sliding in many industrial applications like in building industry for anti-seismic applications. They all have steel or stainless steel supports covered with an antifriction layer in bronze or metal & PTFE.

3 main types of antifriction layers 

SINTERBRONZE : this production process, basis of the CBP Know-How, corresponds to the bearings sintering technique of thin bronze bearings, according the original pattern registered by the designers of the first combustion engines. It consists in spreading a bronze powder layer on a steel sheet, to place it in a continuous furnace in order to obtain a steel + sinterbronze plate which will then be used either to realise plates and thrust washers or cut to length, according the requirements of the production, for the press forming of bearings and bushings. Different bronze alloys are available depending on the customers applications (see Technical sheets oppposite).

WHITE METAL ALLOY :  CBP has its own foundry, equipped with a centrifugal process, in order to realise the white metal layers made of tin and placed on steel or bronze backings. A specific preparation takes place prior to this operation, in order to ensure a perfect sticking of the layer’s surface, guaranteeing optimal calorie elimination and prolonged life. Different alloys are also available.

PTFE : CBP ensures the continuation of the PYDANE (R) Bushings, Thrust Washers and plates references which formerly appeared in the SKF catalogue. This range of products is composed of parts with a 316 TI Stainless Steel backing covered with a metal / PTFE fabric. SKF, at the origin, registered a pattern and conceived the machine to manufacture this specific multilayer material of the PYDANE (R) references. CBP then bought this equipment and produced these parts for SKF (as OEM) during more than 20 years. In 2007, the commercialisation has been overtaken in direct by CBP. The selflubricating structure of the metal/PTFE layer, welded on the Stainless Steel backing, offers a good sliding coefficient and gives the products a high resistance even in particularly corrosive environments. 

                                                     

The optimised industrial organisation of CBP guarantees a constant quality that responds to constraints imposed by the most demanding customers. CBP has its own range of products but is also able to answer each customer’s specific demands in terms of quality and shapes.

The most flexible means of production and CBP’s know-how allow the production of a diverse range of intricate products : CBP responds to a very large number of shapes such as alveolus sliding layers, grooves, holes, and oil baths, in order to improve the lubrication or even simple or double notches and locating or semi-locating for centring. All manufactured products, from the sliding bushings and antifriction bearings to the spherical bimetal alveolus thrust washers, may be worked out with particular specifications in accordance with the customer’s requirements.
