4T-M238849/M238810 bearing reference breakdown
Below we will break down the 4T-M238849/M238810 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.
M - Denotes the bearing as being part of the medium series
