Does the Camry exhaust camshaft have bearing shells?

[WyattFitz]

The Camry exhaust camshaft does not have bearing shells. The camshaft is hollow with an oil passage in the middle, through which engine oil is distributed to each journal. The absence of bushings is generally aimed at simplifying the structure, reducing the number of parts, saving machining time and bushing materials, and lowering costs. The camshaft bears relatively light loads, and with proper lubrication, it can have a long service life. Some diesel engines also operate without camshaft bushings. The Camry measures 4900mm in length, 1840mm in width, and 1455mm in height, with a wheelbase of 2825mm. It is equipped with 2.0L and 2.5L naturally aspirated engines, and also offers a hybrid version that combines a 2.5L naturally aspirated engine with an electric motor.
