This International Standard specifies dimensions for lubrication holes, grooves and pockets for bearing bushes.
These dimensions can be entered, e.g. on drawings, using the designation examples. Their use depends in
particular on the specific operating conditions.
In addition, it enables the user to assign the different types of lubricant feed and distribution to plain bearing bushes
made of copper alloys, thermosetting plastics, thermoplastics or of artificial carbon.
NOTE Different types of lubricant feed and distribution for plain bearing bushes made of sintered metals have not been specified
due to the fact that these bushes are soaked with lubricant. Plain bearing bushes made of artificial carbon are not lubricated with
oil or grease.
