The MT post code indicates the use of non-standard oils for specific bearings. The amount of grease in the bearing is different from the standard filling amount (25%~30% of the free space inside the bearing), and is identified by an additional letter:
A: the use of grease is less than the standard dosage.
B: the use of grease is greater than the standard dosage.
C: the use of grease is more than B.
8) other features. The letter V and the other letter (such as VA) are combined with three numbers to identify a variant of the standard design that can not be expressed with the existing other post code. Such as:
/VA201 – kiln bearing.
/VA301 – cylindrical roller bearings for traction motors.
