Oiles 300 Oil-impregnated expanded cast iron bearings

The Oiles 300 series bearings are formed of oil-impregnated porous cast iron, which is produced by actively leveraging the cast iron growth phenomenon.

Features

Consumes significantly less lubricant than copper alloy bearings.
Oil-impregnated sintered bearings are available in a bigger sizes.
Standard machining products and materials are available in a variety of sizes.
Maintains a good oil film and has excellent wear and seizure resistance.
Sliding surface shapes and motion forms are unrestricted.
