FAQ

What does the 'M' suffix signify in 30307M?

The 'M' in the Timken 30307M designation typically indicates a machined brass cage. This type of cage offers high strength and is suitable for high-speed applications and can withstand significant vibration and acceleration.

Is this bearing pre-lubricated?

No, new tapered roller bearings like this are typically coated with a rust-preventative oil for transport and storage. They must be lubricated with the appropriate grease or oil according to the application's requirements before being put into service.

Can the cone and cup be interchanged with parts from other manufacturers?

While the overall bearing dimensions (30307) are standardized, the internal geometry and roller profiles can vary between manufacturers. For optimal performance and bearing life, it is strongly recommended to use cone and cup assemblies from the same manufacturer and not to mix components.
