803146/803110 Imperial Tapered Roller Bearing 41.275x88.9x30.163mm

Thick-Wall Inner Ring: The 41.275mm bore combined with an 88.9mm OD creates a highly rigid inner structure, resisting deformation under extreme load spikes.
Precision Alignment: Tapered rollers effectively manage simultaneous radial forces and thrust loads while retaining exact gear meshing
alignment. Manual Assembly Quality: Moving away from standard factory automated lines, our dedicated manual assembly process ensures each bearing meets strict rotational tolerance checks.
Standard Imperial Fit: Directly interchangeable with major international brands following ABMA specifications.

Product Introduction

The 803146/803110 is a rugged inch-size single-row tapered roller bearing designed for robust mechanical drivelines. Sharing the 3.500-inch OD outer cup with the 803110 series, this unit features a smaller 41.275 mm (1.625 in) inner bore cone (803146). This geometric design provides a significantly thicker inner ring cross-section, ideal for handling severe shaft deflection and high compression stresses. Crafted from premium GCr15 chromium steel, this bearing is widely imported by B2B auto parts wholesalers serving demanding terrains in South America, Africa, and Central Asia.

Applications

Light-to-medium commercial vehicle differentials and transmission shafts.
Tractor wheel hubs and agricultural PTO (Power Take-Off) drives.
Industrial conveyor drive rollers and gear reducers.

FAQ

Q: What is the primary difference between 803146/803110 and 803149/803110?
A: They use the same 803110 outer cup (88.9mm OD), but the 803146 has a 41.275mm (1.625 in) bore, offering a thicker cone wall compared to the 44.49mm (1.7515 in) bore of the 803149.
Q: Is it possible to buy the cup and cone separately?
A: Yes, we provide flexible B2B ordering and can supply the cone (803146) or cup (803110) independently to suit your inventory needs.
