Tough As Nails Tapered Roller Bearing Single Cone, Precision Steel Straight Bore With Drive Keyway, 4.5 Inch ID By 1.94 Inch Width For Heavy Semis And Field Machinery Overhaulas
✔️ Solid alloy steel cone takes heavy axial loads securely
This single precision inner ring pairs with a matching outer cup to form a complete tapered roller bearing assembly sized for 4.5 inch bores by 1.94 inch widths. You will commonly install it on semi truck drive axles or mining conveyor spindles where steady rotation and tight tolerances keep operations running smoothly.
✅ Single high alloy steel cone matches perfectly with separate outer cups to build full bearing units✅ Open design lets you pack fresh grease directly onto the roller path for extended service life
✅ Stamped steel cage maintains even roller spacing to reduce drivetrain vibration and operating noise
✅ Fits standard 4.5 inch shaft bores and 1.94 inch width specifications without custom machining
💡 How does a single tapered roller bearing cone improve heavy machinery uptime protection? This robust inner ring manages combined forward pull and downward weight while keeping rotating components aligned under tough conditions.
- Heat treated alloy races distribute stress evenly across wide contact surfaces to protect spinning shafts
- Open chamber layout gives fleet technicians direct access for scheduled grease application and easy preload tweaks
- Simple mating geometry makes these units handy for quick replacements on older semi frames and agricultural gearboxes
