FAQ
What does the ‘L125’ suffix in B-66 L125 signify?
The ‘L125’ suffix, along with the ‘Lube Code: 125’ on the label, indicates a specific type of factory-applied lubricant. This is crucial for applications where re-lubrication is difficult or for ensuring compatibility with the operating environment’s temperature and conditions.
Is this an open or closed-end bearing?
The Koyo B-66 is a drawn cup needle roller bearing with open ends. This design is suitable for through-shaft applications and provides good lubricant retention while being cost-effective.
Can this bearing handle axial loads?
No, drawn cup needle roller bearings like the B-66 are designed exclusively for radial loads. They should not be subjected to any axial (thrust) loading. If your application has combined loads, a different type of bearing would be required.
