FAQ

What is the difference between the LM12749 cone and the full bearing?

The LM12749 is only the “cone,” which includes the inner ring and the roller assembly. To make a complete single-row tapered roller bearing, it must be paired with the corresponding “cup” (outer ring), which has the part number LM12710.

Is this bearing pre-lubricated?

Tapered roller bearings like the LM12749 are typically shipped with a light preservative oil to prevent corrosion. They are not pre-greased for operation. The end-user must apply the appropriate type and amount of lubricant (grease or oil) based on the specific application’s speed, load, and temperature requirements during installation.

What does the “- 20024” suffix in the part number signify?

The “- 20024” is a Timken internal code that specifies this part as the cone assembly only, corresponding to the base number LM12749. It helps in precise inventory and part management but does not alter the fundamental geometry or compatibility of the LM12749 cone.
