Durable and reliable
Using these for a custom seedling sorting machine. They handle the repetitive motion perfectly. The copper layer provides excellent heat dissipation. Highly recommend for DIY agricultural projects.

No more squeaking
Replaced the old plastic bushings in my greenhouse window openers with these SF1 bearings. The difference is night and day. Completely silent and moves freely without any grease.

Good quality, precise sizing
Ordered the 15mm variant. The inner diameter was spot on for my shaft. It took a little force to press fit, which indicates good tolerance. Works well for my automated irrigation arm supports.

Fast shipping and the product matches the description perfectly. The oil-impregnated liner ensures long life without maintenance. Using them to upgrade my garden tool hinges.

Solid industrial component
Great bearing for the price. I used the 18mm size. It's thin-walled but very strong. Just make sure your housing is smooth to prevent wear on the outer copper layer during installation.

Perfect fit for my garden trellis joints
I used the 16mm size to reinforce the pivot points on my heavy-duty tomato stakes. The self-lubricating feature is great because I don't have to worry about oil dripping onto my plants. Smooth operation even after weeks of wind exposure.
Q: Do I need to add grease or oil before installing?
A: No, these are self-lubricating bearings. The PTFE liner provides sufficient lubrication for operation. Adding external grease is not necessary and may attract dirt.
Q: Are these suitable for high-speed rotation?
A: SF1 bearings are designed for high-speed, low-load applications. They perform excellently in mechanisms with rapid oscillating or rotating movements.
Q: Can these bearings be used outdoors in rainy conditions?
A: Yes, the SF1 composite material is resistant to corrosion and moisture, making it suitable for outdoor gardening applications like stake supports.
Q: What is the wall thickness for the 17mm inner diameter version?
A: The standard wall thickness for our SF1 series is typically 1.0mm to 1.5mm depending on the specific manufacturing batch. Please measure your housing bore to ensure a proper press fit.
Q: Can I cut these sleeves to a custom length?
A: Yes, you can cut the sleeve to your required length using a fine-tooth hacksaw or a pipe cutter. Ensure the edges are deburred smoothly after cutting to prevent shaft damage.
