Tapered roller bearings are generally of separable design and have a tapered cone and cup raceway between which tapered rollers are arranged. Their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) loads.
According to the dimensional standard difference, tapered roller bearings can be grouped into metric and inch size series.

FAQ: How does HM212049/11 compare with Timken equivalents?
Timken is another major manufacturer of tapered roller bearings, and they use a very similar inch-based part numbering system. For the most common tapered roller bearings, there are direct equivalents between manufacturers like NTN, Timken, SKF, Koyo, etc.
To find the Timken equivalent for NTN HM212049/11, you would typically look for a Timken bearing with the same “cup and cone” numbers. In this case, the Timken equivalent would also be referred to as:
Cone: HM212049
Cup: HM212011
This means that a Timken HM212049 cone combined with a Timken HM212011 cup would have the same principal dimensions and load characteristics as the NTN HM212049/11.
Comparison Points:
Dimensions: Equivalent bearings will have virtually identical bore, outer diameter, and width.
Load Ratings: While dimensions are the same, load ratings (especially dynamic load ratings) can vary slightly between manufacturers due to differences in internal design, roller profiles, and manufacturing tolerances. However, these differences are usually minor for direct equivalents.
Materials and Manufacturing Processes: Each manufacturer has its proprietary steel grades, heat treatment processes, and manufacturing precision, which can impact overall quality, fatigue life, and performance, especially in demanding applications.
Price and Availability: These can vary significantly depending on the brand, region, and supplier.
Conclusion: For practical purposes, the Timken HM212049/11 is considered a direct interchangeable equivalent to the NTN HM212049/11 in terms of fit and function.
