The model number COP.01B90MMEX (often written as COP.01EB90MEX or 01B 90MM EX) refers to a specific type of specialized bearing: an SKF Cooper Split Cylindrical Roller Bearing.
While it shares some functional similarities with yoke-type track rollers (it is a heavy-duty roller bearing), it is technically a split-to-the-shaft bearing designed for mounting in specialized housings, rather than a standard "off-the-shelf" track roller.
