FAQ

What is the significance of the 'M' suffix in the part number 30210M?

The 'M' suffix in a Timken bearing part number denotes a machined brass or bronze cage. This type of cage offers superior strength, stability, and performance under high speeds, high temperatures, and heavy vibrations compared to the standard stamped steel cage.

Can this bearing be used with standard grease or does it require special lubrication?

This bearing is suitable for lubrication with high-quality, lithium-based multi-purpose grease, with an NLGI grade 2 being a common choice. For applications involving extreme speeds or temperatures, it is best to consult the Timken lubrication guide or your machine's service manual for specific recommendations.

What is the recommended mounting procedure for a tapered roller bearing like the 30210M to ensure correct preload?

Proper mounting requires pressing the cone (inner ring with rollers) onto the shaft and the cup (outer ring) into the housing. Preload is critical for performance and is set by adjusting the axial position of either the cup or cone. This is typically achieved using shims, spacers, or a threaded adjustment nut. Incorrect preload can cause excessive heat and lead to premature bearing failure. Always refer to the machinery's service manual or Timken's engineering guidelines for precise instructions.
