Features

Sintered oil impregnated bearings are self-lubricating and require no additional lubrication.
External oil supply is not required to use oil impregnated bearings.

Noiseless bearings are high required technology researches and manufacturing technologies. Such factors as material, shape, pore distribution, chemical composition and the type of oil used determine how well bearings perform.
