Withstood high load testing
We tested these under significant static load in our workshop. They held up without deformation. Highly recommend for heavy-duty bushings.

Perfect for automotive suspension
Used these SF1-4050 bearings for a suspension rebuild. The self-lubricating feature saved me a lot of time on grease fittings. Fit was precise and noise levels are negligible.

Good quality, slight initial odor
The bearings are well-made and fit the shaft perfectly. There was a slight chemical smell upon opening the package, but it dissipated after a day of installation.

No grease needed
Exactly what I needed for a clean machinery application. The oil-free liner works great and keeps dust from sticking like it does with traditional grease.

Great for CNC machinery
Installed these on a CNC linear guide. Smooth operation and the temperature range is sufficient for our operating environment. Will order again.
Q: Can I cut these bearings to a specific length?
A: Yes, they can be cut to size using standard machining tools. Please ensure deburring is done after cutting to maintain fitment.
Q: What is the expected lifespan under continuous rotation?
A: Lifespan varies by load and speed, but under standard PV values, these bearings offer extended service life compared to traditional bronze bushings.
Q: Are these resistant to water exposure?
A: They have moderate water resistance suitable for occasional exposure, but we do not recommend continuous submersion for optimal longevity.
Q: Is a press fit installation required?
A: Yes, these are designed for press fit installation into a housing bore to ensure stability and proper heat transfer during operation.
Q: Are these compatible with hardened steel shafts?
A: Yes, the SF1-4050 composite material is designed to work efficiently with hardened steel shafts to minimize wear on both components.
