FAQs
How many ball bearings are in one pack?
Each pack contains 72 ball bearings.
What type of grease is included?
The pack includes a tube of white lithium grease, suitable for bearing lubrication and protection.
What is the accuracy of the ball bearings?
The ball bearings are accurate to 1 micron.
Can I use these bearings in any bicycle component?
These bearings are specifically 1/8" in diameter and are intended for bicycle hubs and bottom brackets that require this size. Always check your component's specifications.
How often should I service my bearings?
This depends on riding conditions. For regular use, servicing every 6-12 months is recommended. For off-road or wet conditions, more frequent servicing may be necessary.
Are these sealed bearings?
No, these are loose ball bearings designed to be installed with grease into a bearing race, not pre-sealed units.
Troubleshooting
Bearings feel rough or not smooth
Ensure bearings are properly seated and that no debris is present. Re-grease thoroughly and check for any damage to the bearing races.
Component feels loose after installation
Adjust the bearing preload or tension according to the specific component manufacturer's instructions. Do not overtighten.
Grease seems insufficient for multiple services
For extensive servicing or multiple bicycles, consider purchasing additional compatible grease separately.
