  • 17 mm bore fits standard 30203 housings
  • Dynamic rating 20.8 kN, static rating 21.8 kN

Product Identity

The Unique-Bargains 30203 is a single-row tapered roller bearing set supplied as a cone and cup assembly. It is engineered for machinery that must handle combined radial and axial loads at moderate speeds, such as automotive axle systems or conveyor equipment. The chrome-steel construction provides the hardness required for high-load durability in industrial power-transmission applications.

Installation Checklist

Verify that the shaft diameter matches the 17mm bore and that the housing bore matches the 40mm outside diameter before ordering. Confirm the assembly can accommodate the 12mm total thickness within the available axial space. Because the cone and cup are separable, ensure the mounting procedure allows independent seating of each component and that the application does not require a sealed or pre-lubricated unit.

Component Benefits

The separable cone and cup design allows the inner ring with roller and cage assembly to be mounted independently from the outer ring, which simplifies installation, removal and routine inspection. Interchangeable components mean a worn cup or cone can be replaced individually without discarding the entire bearing. The geometry distributes combined loads evenly across the rollers, supporting a dynamic load rating of 20.8kN and a static load rating of 21.8kN.

Highlights

  • Handles combined radial and axial loads
  • Separable cone and cup simplify installation and maintenance
  • Chrome steel construction for high-load durability
  • 17 mm bore fits standard 30203 housings
  • Dynamic rating 20.8 kN, static rating 21.8 kN

Questions about this item

Does the 30203 package include both the cone and cup, or must the cup be purchased separately?

The 30203 set supplies both the inner ring with cage assembly and the outer ring, so no additional bearing components are required for a standard installation.

Which 30203 dimensions should I verify to ensure this bearing fits my shaft and housing?

Confirm that your shaft measures 17 mm for the bore and your housing bore measures 40 mm for the outside diameter; the overall width is 12 mm.

What do the 20.8 kN dynamic and 21.8 kN static load ratings mean for a real machine using this 30203 bearing?

The 20.8 kN dynamic rating reflects the load the bearing can endure for a standard operating life, while the 21.8 kN static rating is the maximum load before permanent deformation occurs.
