Frequently Asked Questions

What is the NTN 52618 tapered roller bearing cup used for?

The NTN 52618 tapered roller bearing cup is used in industrial machinery to support radial and axial loads. It is commonly applied in gearboxes, conveyor systems, and heavy equipment where precise shaft alignment and load distribution are critical. This cup works with a compatible cone (MPN 52375) to form a complete bearing assembly.

What are the specifications of the NTN 52618 bearing cup?

The NTN 52618 tapered roller bearing cup has a 5 37/64 in bore, 6 11/64 in OD, and 1.031 in cup width. It is made of alloy steel and uses the inch system of measurement. The compatible cone manufacturer part number is 52375. This cup is designed for use with NTN cones to ensure proper fit and performance.

Where to buy the NTN 52618 bearing cup worldwide?

You can source the NTN 52618 tapered roller bearing cup from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time. 3G Electric supplies genuine NTN components for industrial applications.

How to select the correct NTN tapered roller bearing cup?

To select the correct NTN tapered roller bearing cup, match the bore, OD, and width to your application's shaft and housing dimensions. Verify the system of measurement (inch) and ensure compatibility with the cone part number (e.g., 52375). NTN alloy steel cups are suitable for heavy loads. Consult a bearing selection guide for load ratings.
