Wrapped bronze bushing material, large lubrication depots, heavy maintenance

FB092 bronze bushing is is basically the same kind of bushing as FB090 . The only difference is that the 092 version has complete holes for the storage of the grease, instead of the diamond shaped pockets of the 090 bronze bushings version.

Economic solution for bronze bearing application due to a thin wall thickness bearings material.

Our standard material is CuSn8, alternatively we also can supply a CuSn6 bronze grade. The hardness of CuSn6 will slightly be lesser.

The bronze holes have the advantage of storing more lubricants than the pockets and therefore, the maintenance intervals can be extended.

Another advantage is that the greasing holes of the bronze bushing material is also able to store grease for a much longer time during the bearing’s lifespan. As the pockets of the standard bronze bushing version are about 0.5mm deep, the holes go through the complete wall thickness of the bushing. Once the bushing starts to wear, the storage capacity of the standard bronze bushings becomes comparatively lesser  for the bronze bushing version.

As such, bronze bushing can guarantee a more sufficient lubrication for a longer period during the life time of the bushing.

High load capability and good stability with low abrasion. Suitable for rough working conditions, good corrosion resistance.

FB092 bronze bushing material is made of CuSn8 bronze material. Before rolling into thin-wall bearing, the greasing holes  are processed evenly and orderly on the surface of the material. After assembly, lubricating grease is injected and then used with end face seal. At present, the material has been used in conveyer, elevator, winding machine, leveling machine and other medium – load, low – speed occasions.

Bronze Bushing can also be manufactured with seals for an extended bearing life, as seals help to keep harmful abrasive particles out of the bushing and contain the grease inside the bushings.

Special dimensions and imperial sizes are available on request.
