Perfect for high heat applications
Used these in a dryer assembly mechanism. No oil needed and they handle the heat well.

Hard to install without tools
Product is good but tight fit required reaming. Make sure you have the right tools.

Good quality, slow shipping
Bearings are great quality but took a week to arrive due to custom sizing.
Q: Do I need to add grease during installation?
A: No, the graphite plugs provide self-lubrication throughout the lifecycle.
Q: What shaft tolerance is recommended?
A: We recommend h9 or g6 shaft tolerance for optimal performance.
Q: What is the standard lead time?
A: Standard sizes ship in 2 days, custom orders take approximately 5 days.
Q: Can you make 6mm ID instead of 5mm?
A: Yes, please contact us for custom sizing options and lead times.
Q: Can these be used underwater?
A: They are corrosion resistant but not sealed for continuous submersion.
