23244EMKW33C4 bearing reference breakdown
Below we will break down the 23244EMKW33C4 bearing reference and provide an explanation for each section provided it can actually be broken down. We can split it into 3 parts the prefix, suffix and body of the item code.
The suffix can be found at the end of the bearing number:
Suffix
W33 - Which denotes a lubrication groove and lubrication holes on the outer ringK - Which indicates a tapered bore, taper 1:12
C4 - Denotes an internal radial clearance higher than C3
EM - Indicates an ultage design, massive brass cage
The body of the bearing reference is what is left after removing the suffix and the prefix:
