Wrapped bronze bearings

THN Wrapped Bronze Plain Bearings 01 2

Long service intervals under severe operating circumstances.

Wrapped bronze bearings are ideal for applications where there are high levels of contamination. Their running surface is provided with diamond-shaped lubrication pockets or a hole pattern. The lubrication pockets must be filled with grease when the bearing is installed. The wrapped bronze bearings are produced according to the ISO 3547.

Wrapped bronze bearings are made entirely from phosphor bronze CuSn8. CuSn8 is characterized by the purity of the alloy with only a very low level of impurities. Wrapped bronze bearings are produced from strips that are subsequently wrapped and calibrated.


Wrapped bronze bearings must be lubricated with grease or oil on installation. A good quality lubricant is essential as it will reduce friction and wear by forming 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.
