Atlas Copco SB breakers: minimize service, minimize total cost of ownership

SB breakers have been designed to be the most reliable on the market. And even when they need attention, they are easy to service. For example, the double tool retainer bars minimize stress and wear on the working tools. It´s easy to change the working tools thanks to the patented retainer bar lock system and replacing the floating working tool bushing can be done by the operator on-site with standard hand tools. The length of the bushing also provides excellent guidance for the working tool, which means less wear.


Atlas Copco Chisel Paste is a specially designed grease with solid lubricants (such as graphite and copper) used for lubricating the wear bushings of hydraulic breakers. It avoids damage and prevents cold welding in the area of the bushings.

Standard greases (such as those used on excavator bearings) are not designed for the high temperatures that result from the friction between the working tool, bushings and retainer bars when your hydraulic breaker is in operation. Standard greases often liquefy and disappear. Without greasing, the parts subjected to friction will suffer from accelerated wear.

Atlas Copco Chisel Paste reduces the cost of operation by extending the lifetime of the wear parts and reducing the risk of working tool fractures.
