FAQ

What does the 'M' suffix in 30204M signify?
The 'M' suffix in Timken's nomenclature typically indicates a machined brass cage. This type of cage offers superior strength and performance in applications with high speeds, heavy loads, or significant vibration compared to a standard stamped steel cage.

Is this bearing pre-lubricated?
No, tapered roller bearings like the 30204M are typically shipped with a light preservative oil to prevent corrosion. They are not pre-greased. The end-user must apply the appropriate grease or oil lubrication based on the specific application's speed, load, and temperature requirements during installation.

Can the cone (X30204M) and cup be purchased separately?
Yes, one of the key features of tapered roller bearings is their separability. The cone assembly (inner ring, rollers, cage) and the cup (outer ring) can be mounted independently. Timken sells these components under separate part numbers, but the 30204M-90KM1 part number represents a complete, matched set.
