Product Description

The Bronze Backed Bushing, combined with (Polytetrafluoroethylene), is a metric bearing specifically designed for bridge applications. The bronze backing material provides excellent strength and wear resistance, while the lining enhances lubrication and reduces friction, resulting in a longer service life and smoother operation.

The bronze- composite construction offers a unique combination of properties that are ideal for bridge bearings. The bronze backing ensures structural integrity and durability, while the coating provides low-friction and self-lubricating properties. This combination makes the bearing suitable for handling heavy loads and dynamic conditions typically encountered in bridge structures.

The metric size of the bearing allows for precise fitment and installation, ensuring the smooth and reliable operation of the bridge. The bearing's design and material choice also make it resistant to corrosion and environmental degradation, ensuring long-term performance and reliability.

In summary, the Bronze Backed Bushing with is a robust and reliable metric bearing for bridge applications, providing excellent strength, wear resistance, low friction, and self-lubrication. Its precision fitment and resistance to corrosion ensure smooth and reliable bridge operation over the long term.

 

composite sliding bushings are manufactured according to DIN standard sizes, where the size of the outer diameter (OD) is correlated to the wall thickness and the inner diameter (ID).

The bronze bushing can be considered as a higher quality standard composite bushing due to its bronze backing. Not only that it has better sliding abilities once the layer is worn off, but the bronze backing is also non corrosive. This can be of an advantage in humid and offshore applications.

 

The bronze bushing is manufactured in a sintering line in which the bronze powder is first melted onto the carrier material, giving it a rough surface 20 to 30 µm thick. During the second step, the is melted onto the carrier material and binds into the rough bronze powder surface. After the sintering process, the raw material panels are rolled according to the standard thickness

The next step will be to cut the raw material into the rectangular shape, which will be rolled into a rough cylinder. The last step will be to calibrate the raw cylinder by pressing it into a housing and pushing a suitable pin with the correct tolerance through the bushings. This process will force the pads to assume their full round shape. As a finishing touch, the chamfers will be cut from the sockets.

1. A mixture of modified polytetrafluoroethylene () and lead (Pb) 0.01-0.03mm a wear-resistant material, which can form a transfer film during operation to protect the countershaft.
2. The copper powder layer, 0.20-0.3mm, improves the bonding strength of /Pb and the copper layer, and has good bearing capacity and wear resistance. Higher thermal conductivity can quickly transfer heat generated during operation.
3. The copper base plate is 0.7~2.3, which improves the bearing capacity and heat transfer of the bearing, and has better corrosion resistance.

SF-1B bronze bearing is of high safety factor,it is particularly suit for working condition ofhigh temperature and where no oil can be added or wherethe machine must work successively for long time.The bushing is widely used in steel metallurgy industry including sliding ways of successive casting machines,cement grouting pumps and spiraling conveyers for cement.It can also be pressed into a steel housing and work as an assembly;it can also be made as flange type which can move both in radial and axial directions.

Wear plate made from SF-IB material can be used in sliding part of bridge underprop.It can stand pressure of 130N/mm2 if we use a thicker wear layer and can be substitute of pure plate.

Bronze backed, Bronze with Series - Metric Bushings


Bronze Bushing Series is particularly appropriate for high temperature environment where no oil is efficient and the machine must be under successive long period working condition.
Bronze Bushing Series is often used in steel metallurgy industries in applications such as bushes for roller grooves of successive casting machines, cement grouting pumps, and screw conveyers for cement. They can also be composed in steel housing or fabricated into flanged bushes which can move both in radial and in axial directions.

This product is tin bronze based powder inside and surfaced and filled with anti-high-temperature material. It is very safe and specially used in the place can’t stop for repair and can’t add oil because of high temperature.
This product has been widely used in various mechanical sliding parts, such as printing machine, elevator, textile machine, tobacco machine, fitness machine, hydraulic conveyor, micro-motor, solenoid valve, automobile and agricultural and forestry machinery.
 
Rolling bearing is a kind of rolling bearing, which is based on high quality cold-rolled steel plate and sintered with porous spherical bronze powder in the middle, and then sintered with a mixture of and fiber on the surface of porous spherical bronze powder, and rolled.
This product has the characteristics of small friction coefficient, abrasion resistance, good corrosion resistance and self-lubrication.Using this product can reduce the cost, reduce the mechanical volume, avoid the phenomenon of shaft biting and reduce the mechanical noise and other characteristics.

 

 

Six factors related to bearing life:

 

(1) [N/mm2] Load P

Larger loads and bearing service life is short; load fluctuation is bigger, larger influence on bearing life, bearing shorter life expectancy; wh, in any case, the maximum load can not be more than the theoretical maximum permissible value of the load. The load is equal to the actual working load divided by the area of the bearing, the formula is P=F/ (D*B).

(2) speed [m/s] V and PV

The working life of the bearing depends on the PV value, that is, the actual load [N/mm2] P and the sliding speed [m/s] V product, the smaller the PV value, the longer the bearing life.

(3) [oC] T

Bearing life also depends on the use of the bearing temperature, so in the design and selection of the relevant parts of the heat dissipation characteristics.

(4) surface roughness of grinding parts

The contact surface roughness of the parts of the bearing and the bearing of the bearing should be between Ra0.2~Ra0.8, and the bearing can not be sharp in the process of assembly and use.

(5) parts of the surface material of grinding, grinding parts surface rough degree is a factor influencing the service life of the shaft sleeve, generally a surface requirements reach less than or equal to 0.4 m Ka.

(6) other factors such as the design of the bearing seat, the lubrication condition, etc..

Strusture

 

1. /fibre mixture thickness 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the /Fibre mixture.
3. Bronze backing, provides exceptionally high load carrying capacity, excellent heat dissipation and very good corrosion resistance.
