Standard greases (i.e, 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 the hydraulic breaker is in operation. They liquefy and disappear. Without greasing, the parts involved in the friction will suffer from accelerated wear.
Chisel Paste is a mineral-oil-based paste containing an aluminium content soap and solid lubricants (such as graphite and copper) with excellent release effect and ambient working temperature range from -20°C to 1100°C/(-4°F to 2012°F), suitable for applications both in cold weather and in high temperatures. High metal content acts ball bearing to minimize high-temperature friction between the surfaces in contact, resulting in less wear between the chisel, retainer bars and bushings. As a result, Epiroc Chisel Paste reduces the cost of operation by extending the lifetime of the wear parts and reducing the risk of working tool fractures.
Bio chisel paste
Epiroc Bio chisel paste is a breakthrough product of the year for the construction and mining industry. The product is approved from the European commission for usage in environmental sensitive applications. The formulation is based on special synthetic esters that are easily biodegradable.
The grease is specially made for hydraulic breakers for lubri cating the wear bushings to avoid both wear as well as working tool breakage. Inside the hydraulic breakers, the ambient working temperature reaches up to 1100°C under extreme load. The standard greases available in the market are suitable for use in bearings BUT they liquefy and disappear at high tempera tures. Without adequate greasing, the parts suff er accelerated wear, thereby increasing the cost of operation.
