• the bearing shells have a so-called exposure to their bearing shell ends, by which one understands an area adjacent to the partial areas, in which the wall thickness of the bearing shell is reduced.
• the disadvantage of such exposures is that lubricating oil is discharged laterally, i. can escape in the axial direction, whereby the lubricating oil pressure drops during operation. This can lead to seizing the shaft.
• oil grooves are provided in the region in which the exposure is usually introduced, which grooves are arranged parallel and immediately next to one another. These grooves are made by drilling, leaving between the grooves tapered webs.
• the object of the invention is to provide a bearing shell which has two exposure areas and in which leakage of lubricating oil in the axial direction from the exposure area is prevented. It is also an object to provide a corresponding manufacturing method that ensures the production of grooves in the exposure area in a simple manner.

• the oil grooves of at least the first exposure region preferably extend into the sliding surface region.
• the lubricating oil flows from the neighboring shell into the first exposure area and is accelerated at the end of the exposure area at the transition to the sliding surface area.
• a slowing down of the oil flow would lead to an increase in pressure and would favor an axial escape and escape of the oil from the exposure area.
• the groove sections in the sliding surface area have a greater size Have depth than the groove sections in the exposure area.
• Preferred depths for the groove sections in the exposure area are 0.03 mm and 0.05 mm in the sliding surface area.

• the groove sections may extend over the entire sliding surface region.
• the grooves of the first exposure area are thus in flow communication with the grooves of the second exposure area, whereby the flow of the lubricating oil over the entire bearing shell is additionally favored.
• the groove sections in the exposure area preferably extend up to the partial surfaces.
• the grooves in the first exposure area are wider than in the second exposure area.
• the groove bottom of the oil grooves may be circular, parabolic or elliptical.
• the groove spacing A is greater than the groove width B, wherein A between the center of two adjacent grooves is measured.
• A> B is preferred if a quick wear of the webs between the grooves is to be avoided.
• camshaft bearings in truck engines.

• the bearing according to the invention with two such bearing shells provides that in each case the first exposure region of one bearing shell is arranged adjacent to the second exposure region of the other bearing shell.
• the method for producing bearing shells with a first and a second exposure area, with a sliding surface area between the two exposure areas and with oil grooves provides that boards are separated from a strip material and then these boards are converted into bearing shells, wherein the exposure areas are produced on the strip material and the oil grooves are embossed in the strip material, the severed board or in the prefabricated bearing shell.
