Product Features
- Complete tapered roller bearing set includes cone (2780) and cup (2720) for a full bearing replacement.
- Single-row tapered design provides excellent radial and thrust load capacity in one axial direction.
- Separable cone and cup components simplify mounting and maintenance.
- Heat-treated bearing steel construction resists shock loads and fatigue.
- Interchangeable with major brands including Timken, SKF, NTN, and FAG.
Installation Notes
- Confirm bore diameter is 36.49 mm (1.437 in) and outside diameter is 76.20 mm (3.000 in) before installation.
- This is an open bearing – pack with high-quality grease before installation.
- Single-row tapered bearings must be mounted in opposing pairs (face-to-face or back-to-back) to accommodate axial loads in both directions.
- Inspect the shaft and housing surfaces for damage or wear before installing new components.
- Torque all fasteners to manufacturer specifications and check bearing preload after installation.
