NTN 4T-HM88610PX1 Tapered Roller Bearing Cup

This NTN tapered roller bearing cup has a 2 23/64 inch bore and 0.781 inch width. It is made from 52100 alloy steel and meets ABMA standards. The component operates between -40 and 250 degrees Fahrenheit.

Suits maintenance teams replacing HM88648

This cup matches specific HM88648 and HM88649 cones for forestry, mining, or steel mill equipment. It will not work with cones that have different bore dimensions or profile angles. Buyers needing metric sizes or different load ratings must select another part.

Critical spec: 2 23/64 inch bore diameter

The 2 23/64 inch bore determines cone compatibility and shaft fit. Verify this exact measurement against your housing and cone requirements before ordering. An incorrect bore size prevents proper assembly and leads to premature failure.

Questions about this item

What compatible cone part numbers must I already have for this 4T-HM88610PX1 cup to work?

The cup is designed to mate with cone part numbers HM88648 and HM88649, which are the matching tapered rollers for this specific bearing assembly.

Will the 0.091 in housing fillet radius on this cup clear the existing shaft fillet on my older equipment?

The cup has a maximum housing fillet radius of 0.091 in; your shaft fillet must be smaller than this value to ensure proper seating and avoid interference.

How can I verify the cup is seated correctly after pressing it into the housing?

After installation, confirm the cup sits flush against the housing shoulder and rotates smoothly with the matching cone, showing no binding or axial play within the 0.781 in width.
