The grease formulated by Rocol Ltd, Rocol House, Swillington, Leeds, LS26 8BS, contains finely divided lubricating solids and EP agents to provide a tenacious lowfriction film on the bearing surfaces. The solid lubricant reduces the effect of heavy loads which tend to lead to the grease being squeezed from between the fifth-wheel and trailer rubbing plate.
The company. says the grease operates efficiently between minus 30deg C and 185deg C and contains corrosion inhibitors active over the temperature range.
In addition, the grease has a high resistance to attack from water, steam, brine and many other chemicals and solvents.
