BEARING CONE
Frequently Asked Questions
Q: What is the CR 081274 bearing cone?
A: The CR 081274 is the inner race (cone) of a tapered roller bearing assembly used in lift truck masts and load wheel hubs. It is mounted on the shaft or axle and rotates with the wheel or carriage.
Q: Is the CR 081274 cone compatible with Crown, Toyota, and Raymond equipment?
A: Yes, the CR 081274 is manufactured to Crown specifications and is compatible with multiple Crown, Toyota, and Raymond electric lift truck models. Always verify the matching cup part number and bearing bore diameter for your specific equipment.
Q: Must the CR 081274 cone be replaced with the CR 081273 cup?
A: Yes. The CR 081274 cone and CR 081273 cup are matched pairs engineered for precise bearing clearance and load capacity. Replacing only the cone or only the cup without its mate causes rapid bearing failure.
Q: What material is the CR 081274 bearing cone made from?
A: The CR 081274 is constructed from hardened alloy steel with precision-ground rolling surfaces. The tapered design distributes radial and axial loads efficiently in continuous material handling duty.
Q: What symptoms indicate the CR 081274 cone is failing?
A: Failing bearing cones produce grinding or squealing noise from wheel hubs or mast assemblies, loose or wobbly wheel movement, and increased heat in the bearing area. Inspect the cone raceway for spalling, pitting, or discoloration.
Q: How often should the CR 081274 cone be lubricated?
A: Follow the OEM maintenance schedule for bearing lubrication, typically every 500 operating hours or per weekly inspection. Use the correct bearing grease type specified in your equipment manual. Over-greasing causes overheating and early failure.
