DIAMET CORPORATION Product Lineup

We offer the "Low Cost High Performance Iron-Copper Sintered Oil-Embedded Bearing / F350," which has excellent sliding properties due to its high copper coating rate. The reduction in copper content is compensated by the use of special copper powder, achieving a high copper coating rate on the sliding surface. Sintered oil-embedded bearings are utilized in various fields, including bearings for motors, due to the excellent mass production capabilities and homogeneous properties characteristic of powder metallurgy.

Low-friction iron-copper sintered oil-containing bearings are used in motors that adjust the opening of electronic control throttle valves. Since the electronic control throttle is installed near the engine, it must be able to withstand a wide temperature range and have vibration resistance. Therefore, bearing materials that are impregnated with a special fluorine oil capable of handling a wide temperature range, and that have a copper-rich microstructure controlled in the inner diameter surface, demonstrate excellent wear resistance, low friction coefficients, and anti-seizure properties, contributing to improved fuel efficiency, reduced harmful exhaust emissions, and significant cost reductions.

The bearings for EGR (Exhaust Gas Recirculation) are used in the valve that directs a portion of the exhaust gas to the intake side, and they are utilized in a wide range of exhaust gas environments, from atmospheric temperatures to high temperatures where lubricating oil cannot be used. Therefore, by adding a large amount of solid lubricants to the bearing material itself, we have achieved a material that excels in self-lubrication at high temperatures and has excellent oxidation resistance, contributing to the reduction of NOx and improved fuel efficiency in automobiles.

The coaxial precision of the inner diameter is improved through integrated manufacturing. It is possible to reduce the contact area while ensuring the shaft holding length, which reduces friction loss.

The thin-walled structure achieves space-saving and cost reduction. By replacing conventional rolled bushes (oil-free type), it demonstrates excellent sliding characteristics.
