Solid bronze bearings are made from CuSn7Zn4Pb7 continuously cast bronze. This material is 85% copper and has very good sliding characteristics. All the surfaces of this plain bearing are machined.

Many other alloys are also available beside the standard material. Most common among these are CuAl10Ni, CuSn10 and CuSn12.


Solid bronze bearings are normally lubricated with grease, but oil is also used in exceptional applications. A good quality lubricant will ensure that friction and wear will be reduced by the forming of a film between the plain bearing and the shaft. For heavily contaminated applications we recommend sealing off the bearing. This will protect both the bearing and the lubricant.

All solid bronze bearings with an inside diameter of 14 mm or more are provided with an axial lubrication groove.
