BEARING CUP
Frequently Asked Questions
Q: What is the CR 081273 bearing cup and what does it do?
A: The CR 081273 is the outer race (cup) component of a tapered roller bearing assembly used in electric lift truck mast and wheel assemblies. The cup works with a matching cone to support radial and axial loads.
Q: Which lift truck brands use the CR 081273 bearing cup?
A: The CR 081273 is compatible with Crown, Toyota, and Raymond electric lift trucks. Confirm your equipment OEM part number matches this Crown part number or verify bore diameter and width before ordering.
Q: Can the CR 081273 cup be replaced separately or must the entire bearing assembly be replaced?
A: The CR 081273 cup and its matching cone (CR 081274) should be replaced as a pair to ensure proper bearing clearance and load distribution. Mixing old and new components causes premature wear and bearing failure.
Q: What material is the CR 081273 bearing cup made from?
A: The CR 081273 is made from hardened alloy steel with precision ground raceways to support rolling elements. Steel composition provides durability under the repetitive loading cycles of lift truck operation.
Q: How do I know if the CR 081273 bearing cup needs replacement?
A: Signs of bearing cup wear include grinding or rumbling noise from the mast or wheels, increased radial play in the wheel assembly, and visible spalling or pitting on the raceway surface. Replace both cup and cone when these symptoms appear.
