Dry-Running Metal-Reinforced Plastic Sleeve Bearings
 |
Combine slippery plastic with the strength of metal. The PTFE core is naturally slippery, so you’ll never have to add lubricant. These bearings also keep your workspace clean with no lubricant to drip or flake and attract dust. Compared to all-metal bearings, they are lighter.
With no moving parts, sleeve bearings are the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.
PTFE with 17-4 PH Stainless Steel Shell—The highest load capacity of any sleeve bearing we offer. 17-4 PH stainless steel offers good corrosion resistance but is heavier than aluminum.
