4T-LM67049A/LM67010 bearing reference breakdown
Below we will break down the 4T-LM67049A/LM67010 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 prefix can be found at the beginning of the bearing code:
Prefix4T - The 4T- prefix designates a tapered roller bearing that is made of a special grade of case-hardened bearing steel and is interchangeable with other manufacturers taper with the same part number.
LM - Denotes that the bearing is part of the light medium series
The suffix can be found at the end of the bearing number:
SuffixA - Denotes an internal design change (for inch items only)
