Wrapped bronze perforated bearings, Split Bronze Bushing Widely Used for Mining Machinery.
bronze bushings wrapped rolled bushings are made of forged CuSn8 material and despite their thin-walled structure, they withstand very high loads. Therefore, these bronze bushings are for bronze swinging bushings (oscillating movement), the most common use for rolled bushings.
The excellent tin bronze material provides the bushings with excellent sliding properties and high wear resistance.
rolled bushings are used, on the one hand, in standardised dimensions with lubrication pockets. The advantage of this type of bushing is that it can be shortened to any desired length.
We also offer special designs and sizes according to your specifications.

A tin bronze with excellent sliding properties. The material is particularly suitable when high wear resistance, corrosion resistance and fatigue strength are required.
Due to the thin-walled construction of rolled bushings, they can absorb very high specific forces. These may be higher than for the relatively thick-walled turned bushings. Very high loads are possible, especially with swing bronze Bushingss (oscillating motion).

Flange Slide bearing with hole pattern
Slide bearings with hole pattern LD Slide bearings with hole pattern (LD = long-term lubrication with the depot) are suitable for all types of grease. Bushings with lubrication indents ST can easily be replaced by slide bearings with hole pattern LD. Advantages: Significantly larger grease depot compared to bushings with grooves or lubrication indents Extension of the running time and the relubrication interval compared to ST bushings Collection of dirt and wear particles in the lubrication holes
High load capacity bronze with very good thermal stability, very good corrosion resistance, wear resistant. Hardened shafts are necessary at high loads.

The combination of ever-increasing power density and energy efficiency, combined with ever-increasing demands on service life and cost-effectiveness, lead to ever-higher requirements for components and production. By combining specially developed and manufactured high-performance materials with the most advanced manufacturing technologies for both turned and rolled plain bearings, bronze plain bearings are ideally suited to the current and future requirements of construction and agricultural machinery and the hydraulic industry.
bronze bearing is made of bronze with oil holes evenly distributed on it. When assembling it, the bearing should be lubricated with grease before both ends of the bearing is assembled with seals.FB092 has the advantages of abundant oil storage, easy-to-assemble or easy to be machined, etc. It can substitute bushings made by complete copper material, in addition, it suits conditions of middle load and low speed including conveying machine. hoisting machine, windlass, aligning machine, etc.

Bushings with lubrication notches are sliding elements that have proven themselves for many years. The lubrication depressions already integrated in the belts are evenly distributed over the entire running surface. They are filled with grease before the shaft is assembled and ensure an even grease film over the entire bearing.
An advantage of the bushes with lubrication pits is that they can be shortened to any desired width without causing any disadvantage to the lubrication pits.
As opposed to the known plain bronze Bushings designs, in which bushing and seal have to be installed separately, it is also possible to obtain bushing and seal as a complete part.
It is not just the bushing and the shaft that are important in the tribological system; lubrication and the environment (for example, air, gas, salt water, dust, etc.) are equally important. The environment is generally not controllable, unlike lubrication.
Lubrication not only improves the sliding properties; further advantages are also achieved:
Friction is caused by the interaction of two bodies under load and movement. To reduce friction and wear, the lubricant performs an extremely important function: it separates the metallic surfaces of the bushing and shaft.
1. Pressing in the bronze Bushings
The bushing is pressed in with mounted seals. A shoulder mandrel with free rotation for the sealing lip between the guide shaft and the shoulder is recommended to ensure error-free installation. Free rotation is necessary so that the seal is not damaged during pressing. The shoulder mandrel should have a leadin chamfer of at least 3 mm x 15°.
However, the bushing can also be pressed in with a plate. Here, the seal is pressed elastically towards the middle of the bushing and goes back to its original position after the press-fitting process.
2. Mounting the shaft
When mounting the shaft, it must be taken into account that the inner diameter of the sealing lip has a smaller diameter than the shaft. Therefore, to allow easy insertion the shaft should have a chamfer of at least 3 mm x 15°. Mounting is further simplified if the shaft is lightly greased before insertion.
3. Lubricating the bronze Bushings
Without a seal, complete filling of the bronze Bushings via the grease nipple is not guaranteed. In the unstressed area, grease quickly leaks out, whereas the stressed area remains unfilled. The seal causes throttle pressure to be built up in the bronze Bushings during lubrication, whereby only after complete filling of the bushing does the grease escape through the seal. If the bushing cannot be lubricated via a grease nipple, make sure the bushing is well lubricated before mounting the shaft.

| Lubrication condition: oil | small |
| Load: big | small |

The required play of the central bronze bushings depends on the supplied lubrication, the load and the sliding speed.
The table is intended to help you select the required spacing. The curve is designed for general mechanical engineering. With bronze bushings in rough operation, the curve upwards can easily be exceeded.
The tolerance of the shaft must be set according to the required minimum play. The tolerance class should be IT6 for high requirements and IT7 or IT8 in normal cases.
If standard bushings with inside diameter tolerance H9 are used, it is recommended to tolerate the shaft with e or f. For shafts with h tolerance, provided that the bronze Bushings load is not too high the housing bore can be extended from H7 to F7. The bushing attaches to the respective housing and the bushing bore is slightly larger. This means that bronze Bushings clearances that are too small can be avoided.
