Plain & Self-Lubricating Bearings（Mounting Shaft Fits：e7）

Technical Information【PLAIN SELF LUBRICATING BEARINGS】
Since bearings usually receive a lot of frictional resistance that generates heat, lubricants such as oil or grease are used to prevent the seizing or abnormal wear that this frictional heat could otherwise cause. Lubrication-free bushings don't need lubricating oil because the bearing body has a lubricating structure made possible by lubricating oil in the bearing body, or by embedded solid lubricant or the like. Since they don't need lubricating oil, lubrication-free bushings are often used for applications such as precision machinery that makes lubricating oil refilling difficult, and equipment with poor affinity to oil. They also greatly reduce maintenance costs by eliminating the need for regular lubrication and enabling stable operation over long periods. Lubrication-free bushings come in a variety of shapes that can be used for different applications as needed. Examples include straight bushings, collar bushings, flange bushings and housing bushings.

Bushing 500SP1 - Straight, copper alloy, SPB series.

Oiles

Straight oil-free bushing made of copper, with solid lubricant incorporated (graphite). Excellent wear resistance in areas where it is difficult to form an oil film, such as reciprocating movements, oscillating movements and frequent starts and stops. Excellent chemical and corrosion resistance but not recommended for use with sea water.

Drymet LF Bushings - Flanged, multilayer (PTFE), LFG series.

Oiles

Drymet LF bushings incorporate an aluminum housing with a square flange ideal for time-saving assembly, thanks to its bolt-on design. These bushings have excellent wear resistance and a low coefficient of friction. They can be used with or without lubricant. The housing adds an anti-corrosion surface treatment, which makes it resistant to environments exposed to humidity.
