Reliable and consistent quality
Ordered multiple batches for our factory upgrades. Every unit has been consistent in quality and size tolerance. The copper sleeve finish is clean, and they slide onto the shafts without forcing.

Good durability under moderate load
These copper sleeves have held up well in our agricultural equipment. They handle dust and debris better than expected. I deducted one star only because the lead time for the specific F20150 size was a bit long.

Excellent oil retention
The oil-impregnated technology works exactly as advertised. After three months of continuous operation in a dry environment, there is still no sign of wear or increased friction. Highly recommended for chain guides.

Solid performance for industrial chains
We use these in a high-cycle sorting machine. They run smooth and quiet. Just ensure you don't exceed the stated speed limits, or the oil film might not sustain properly. Overall, a great product.

Perfect fit for our conveyor chain system
We replaced our standard bushings with these SF1 series self-lubricating bearings in our packaging line. The installation was straightforward, and the reduction in noise is significant. No more daily greasing required.

Cost-effective maintenance solution
Switching to these self-lubricating bushings has cut our maintenance downtime by half. The sintered bronze material feels robust, and the dimensions matched our CAD drawings perfectly.
Q: What is the difference between models F20100, F20115, and F20150?
A: The numbers typically refer to specific dimensional variations such as inner diameter, outer diameter, and length. Please refer to the detailed technical datasheet attached to the product page to select the exact dimensions required for your chain assembly.
Q: Can I press-fit these bushings into a steel housing?
A: Yes, these sintered bronze bushings are designed to be press-fitted into steel housings. We recommend a standard interference fit (usually H7/p6) to ensure they remain secure during operation without deforming the inner bore.
Q: Are these bearings suitable for outdoor applications exposed to rain?
A: While the SF1 series is self-lubricating, it is primarily designed for dry or moderately humid environments. For constant exposure to water or corrosive chemicals, we recommend consulting our corrosion-resistant series or applying additional protective measures.
Q: What is the expected lifespan in a continuous run cycle?
A: Lifespan varies based on load, speed, and environmental conditions. Under standard operating parameters (within the specified PV value), these bushings can typically operate for thousands of hours without maintenance. Regular inspection is still advised for critical applications.
Q: Do I need to add extra oil before installation?
A: No, the SF1 series comes pre-impregnated with lubricating oil during the manufacturing process. Adding external oil is generally unnecessary unless the application involves extreme speeds or loads beyond the standard specifications.
