Tapered Roller Bearing 24780 NTN without Outer Ring 127x41.275

Cone-type tapered bearing for direct housing raceways

High durability in demanding industrial applications

Main product description

The 24780 NTN tapered roller bearing without outer ring is a precision rolling bearing designed for applications where the outer raceway is integrated directly into the machine housing. Structurally, this product is a cone-type tapered roller bearing, consisting of the inner ring with tapered rollers, optimized for carrying combined radial and axial loads under demanding operating conditions.

In industrial and maintenance markets, this bearing is commonly searched under phrases such as “tapered roller bearing without outer ring”, “24780 NTN cone”, “tapered bearing 127x41.275” and “tapered bearing for housing raceway”, reflecting its practical use in heavy-duty machinery and custom bearing assemblies.

By eliminating the separate outer ring, the 24780 NTN bearing allows the housing to function as the outer raceway. This design reduces the number of components, increases structural rigidity and improves heat dissipation within the bearing unit. The precisely ground raceway and roller geometry ensure stable load distribution, low friction and reliable performance over long service intervals.

The bearing is widely used in industrial applications such as gearboxes, heavy-duty drives, transport systems, machine hubs and specialized mechanical assemblies. With dimensions 127x41.275, it is mounted directly onto the shaft, providing secure positioning and accurate alignment within the bearing housing.

The 24780 NTN tapered roller bearing without outer ring is valued by B2B customers for its high durability, dimensional stability and suitability for applications where conventional bearing designs are not optimal. It is an effective solution for both new machine construction and professional refurbishment of industrial equipment.
