Oil-containing bearing "Polite CLB"

Oil-containing bearing "Polite CLB"

Oil-impregnated bearings that significantly increase the oil content compared to conventional bearings, enabling longer lifespan.

"Polite CLB" is a material that has significantly increased the oil content compared to conventional materials to enhance reliability in applications that require particularly long lifespans, such as fan motors. By using a special method to create copper-coated iron powder and through special sintering, the matrix strength is improved compared to traditional bearing materials, and fine pores are created to achieve low air permeability. As a result, even with a high oil content, it provides bearing performance equivalent to conventional bearings. [Features] - High oil content improves reliability for applications requiring long lifespans. - Low air permeability allows for equivalent air permeability to conventional bearings even with high oil content, enabling comparable bearing performance and reducing oil leakage. - The bearing surface is covered with a copper alloy, providing excellent compatibility and corrosion resistance despite being iron-copper based. - The underlying material is iron, which suppresses wear progression after initial settling. - Switching from bronze-based bearings allows for cost reduction, among other benefits. *For more details, please download the PDF or contact us.

Oil-impregnated bearing "Polite DMP"

Oil-impregnated bearing "Polite DMP"

Oil-impregnated bearings suitable for low speed and high load conditions.

"Polite DMP" is an oil-embedded bearing that enhances a copper alloy matrix by uniformly dispersing a solid lubricant, graphite, in large quantities, thereby reducing metal contact during sliding and improving durability under harsh operating conditions such as low speed, intermittent use, and high load. Due to the high content of solid lubricant, it excels in wear resistance under high load and low speed conditions compared to iron-based and conventional bronze materials, resulting in superior durability. 【Features】 ■ Being based on a copper alloy, it has less galling with shafts and offers high reliability. ■ Can also be used for oscillating motion specifications. ■ This bearing is used by press-fitting into the inner diameter of gears and pulleys and can be used under shaft fixation conditions (please consult a technician). ■ It is also possible to use it without oil in places where oil is undesirable (please consult a technician). ■ Compliant with ELV and RoHS. *For more details, please download the PDF or contact us.

Powder Metallurgy Products: Oil-Impregnated Bearings

Powder Metallurgy Products: Oil-Impregnated Bearings

Continuously researching and developing the "technology of harmony" in terms of shape, material, pore structure, impregnation oil, etc.!

We would like to introduce the "oil-impregnated bearings" that we handle. The function of oil-impregnated bearings is to maintain a small amount of oil, less than a drop (0.05cc), without losing or damaging it within a limited space, ensuring the designated bearing lifespan, which is a significant challenge. We continuously research and develop the "technology of harmony" regarding the shape, material, pore structure, and impregnated oil of oil-impregnated bearings. [Materials] ■ Copper-based materials ■ Iron-based materials ■ Copper-iron-based materials *For more details, please refer to the PDF document or feel free to contact us.

Low-friction iron-copper-based sintered oil-bearing bearing for electronic throttle/F339

Low-friction iron-copper-based sintered oil-bearing bearing for electronic throttle/F339

Bearings with excellent wear resistance, friction coefficient, and seizure resistance using bearing materials impregnated with special fluorine oil.

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. Please feel free to contact us if you have any inquiries. *For more details, please download the PDF or feel free to contact us.
