NTN株式会社　複合材料商品事業部 Product Lineup

We handle the "Twin Bear Fight," which contributes to energy savings in motors. It contributes to energy savings through the torque reduction effect provided by the enlarged diameter on the inner surface. There are benefits such as increased oil content in the bearings and improved circulation. Additionally, starting from an inner diameter of Φ0.6, we can select materials and lubricants, allowing for customization according to specific applications. 【Benefits】 ■ Low power consumption ■ Improved precision ■ Long lifespan ■ Reduction in the number of parts *For more details, please download the PDF or feel free to contact us.

• Other machine elements

We offer sleeve bearings "ARE" that achieve zero environmental emissions using the auto-molding method with "Bearly FL3000." You can choose from a wide range of options. 【Features of Sleeve Bearings "ARE" and "AR"】 ■ Both ARE and AR have the same performance and can only bear radial loads. "ARE" ■ Inner diameter: 3 mm to 12 mm ■ Achieves zero environmental emissions using the auto-molding method with "Bearly FL3000." "AR" ■ Inner diameter: 15 mm to 50 mm ■ Processed from Bearly FL3000.

• Metal bearings

We provide materials that solve wear in liquids and damage to counterpart materials, tailored to specific conditions. These can be used in general underwater (seawater) bearings, as well as vanes, rotors, and casings for vane pumps. 【Features】 ■ Excellent wear resistance in liquids ■ Superior chemical resistance ■ Does not wear down counterpart materials

• Metal bearings

■Usable in special environments ■Long lifespan ■Excellent chemical resistance and water resistance ■Maintenance-free (grease-free) ■Usable at high temperatures (heat resistance up to 260°C)

• Plastic bearings

The fluid dynamic pressure bearing "Dynamic Pressure Bearfight," equipped with a special dynamic pressure groove in a sintered oil-containing bearing, supports the rotating shaft in a non-contact state at low speeds, achieving low noise and long lifespan. 【Features】 ■ High rotational precision at low speeds ■ Low noise ■ Long lifespan and high durability ■ Ultra-compact, capable of accommodating inner diameters of less than 1mm

• Metal bearings

The oil-impregnated bearing "Bearfight CL," which deposits copper material on the bearing surface using proprietary technology, ensures the same friction and wear characteristics as conventional bearings with a low copper content. 【Features】 ■ Reduced raw material costs ■ Usable under low-speed, intermittent, and high-load conditions ■ High sliding performance, surpassing bronze-based bearings ■ High durability, surpassing copper-iron-based bearings

• Metal bearings

The "corrosion-resistant sintered bearings," which can be used in environments where corrosion of metal bearings is likely to progress, such as in fuel and exhaust gases, utilize aluminum bronze to achieve performance that surpasses conventional brass bearings while also reducing costs. 【Features】 ■ Excellent corrosion resistance ■ Excellent wear resistance ■ High sliding properties ■ Reduced raw material costs

• Metal bearings

The oil-impregnated bearing "Self-lubricating Sintered Bearing" made from special graphite excels in friction and wear characteristics in dry environments and ensures high sliding properties under special conditions. 【Features】 ■ Usable in environments unsuitable for oil ■ Excellent friction and wear characteristics; wear amount is 1/4 of that of general copper-based bearings ■ High sliding properties ■ Has conductivity ■ Oil-free and maintenance-free

• Metal bearings

【Features】 　■ Operating temperature range: -40℃ to +130℃ 　■ No lubrication or grease required 　■ Corrosion resistance 　■ Low friction 　■ Low noise *Compared to ball screws

• Metal bearings

We propose materials tailored to usage conditions such as high speed, high pressure, and high humidity environments.

• Electrical equipment parts
• Sealing

The work-specific resin sliding material "Bearly FL3307" is based on a low-friction fluororesin and aims to improve wear resistance, creep resistance, and thermal conductivity. 【Features】 ■ Low friction coefficient under oil lubrication conditions ■ Difficult to experience stick-slip ■ Less prone to seizure and galling ■ Low compressive deformation ■ Low friction coefficient and long lifespan

• Metal bearings

"Stainless steel sintered machine parts and oil-containing bearings" reduce the compression process and achieve cost savings in manufacturing. 【Features】 ■ Reduction in manufacturing costs ■ High strength ■ High corrosion resistance ■ High sliding properties of bearings
