Frequently Asked Questions

What is the NTN SET412 tapered roller bearing used for?

The NTN SET412 tapered roller bearing assembly handles combined radial and axial loads in industrial machinery, automotive drivetrains, and heavy equipment. Its inch-system dimensions (2 1/2 in bore, 4 13/16 in OD) suit applications like gearboxes, conveyor systems, and wheel hubs where precise load distribution is critical.

What are the specifications of the NTN HM212047/HM212011 bearing?

The NTN HM212047/HM212011 is a SET412 tapered roller bearing assembly with a 2 1/2 in bore, 4 13/16 in OD, and 1.51 in cone width. It uses carbon steel rings and a pressed steel cage. This inch-system bearing is designed for high radial and thrust load capacity in industrial applications.

Where to buy NTN tapered roller bearings worldwide?

3G Electric supplies NTN tapered roller bearings like the SET412 assembly worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time on the HM212047/HM212011 bearing.

How to select the correct NTN tapered roller bearing for an application?

To select the correct NTN tapered roller bearing, match the bore (2 1/2 in), OD (4 13/16 in), and cone width (1.51 in) to your shaft and housing dimensions. Verify load ratings and operating conditions. The SET412 assembly with carbon steel rings suits moderate-speed, high-load environments. Consult NTN's catalog for fit and lubrication guidance.
