This is a ball bearing that can be used up to 350°C in a vacuum. By changing the metal of the bearing material or the self-lubricating materials used, it can withstand higher temperatures and atmospheric conditions.
As vacuum ball bearings, there are 1. silver-lead coated products, 2. polymer coated products, and 3. molybdenum disulfide coated products, but in terms of lifespan, NF bearings surpass all of these. Heat resistance largely depends on the base material of the bearings, but in terms of the heat resistance of the lubricants, NF bearings also outperform all of these. We take pride in being able to offer our products at a lower price compared to ball bearings 1 to 3. For high-speed rotation, we accommodate with NF metal using either a crown-type or a pressed-out type retainer.

We offer over hundreds of miniature ball bearings, ranging from ultra-small types with an inner diameter of 1.0mm and an outer diameter of 3.0mm to sizes around an outer diameter of 20mm!
Miniature ball bearings are now essential components in the rotating parts of various equipment. As the downsizing of equipment progresses, there is an increasing demand for smaller, thinner, and quieter designs. NSK Micro Precision Co., Ltd. manufactures a variety of ball bearings tailored to meet these needs. ■ Size Types From ultra-small types with an inner diameter of 1.0mm and an outer diameter of 3.0mm to larger sizes around 20mm in outer diameter, including special types, there are hundreds of varieties. ■ Catalog Contents The "Miniature Ball Bearing Comprehensive Catalog" includes the most commonly used radial ball bearings composed of an inner ring, outer ring, balls, cage, and seals, such as "Single Row Deep Groove Ball Bearings," deep groove ball bearings with a flange on one side of the outer ring, "Flanged Deep Groove Ball Bearings," inch series deep groove ball bearings with a wider inner ring than the outer ring, "Wide Inner Ring Deep Groove Ball Bearings," and deep groove ball bearings with a smaller outer diameter-to-inner diameter ratio than standard, "Thin-Walled Deep Groove Ball Bearings," among many others. ★ For more details, please download the catalog or contact us.
Highly effective in chemical resistance, water resistance, insulation, and non-magnetism! Plastic ball bearings.
Due to rust and corrosion, metals cannot be used... Grease and oil are troublesome... For those of you struggling in special environments, please consult Kashima Chemical Metals Co., Ltd. for all your plastic needs. We can provide products that meet various requirements such as insulation, non-magnetic properties, and lightweight.
The full ball type (without retainer) resin ball bearing is recommended when there is a possibility of issues arising from having a retainer!
Full ball type resin ball bearings do not have retainers, allowing for smooth circulation of the solution within the bearing and making it less likely for impurities to clog the structure. Additionally, in plating lines, metal bearings cannot be used because the plating adheres to the bearings themselves, but plastic bearings can be used in plating baths since they do not get coated. 【Main Applications】 ■ Environments where liquids or solutions containing impurities are present ■ Plating lines for semiconductors and electronic components, cleaning lines ■ Lines in liquids containing impurities, such as underwater ■ Food manufacturing lines where food debris is generated or oil is used *For more details, please download the materials or contact us.
Next-generation ultra-heat-resistant ball bearings with laser cladding.
■Background of Research and Development The maximum operating temperature of commercially available metal ball bearings is approximately 400°C. In higher temperature environments, ceramic ball bearings are used; however, their application is limited due to issues such as impact resistance/strength (load capacity), size constraints, and cost. This research aims to solve existing problems by raising the operating temperature of metal ball bearings from 400°C to 600°C, thereby extending the lifespan of ball bearings, reducing energy consumption due to decreased rotational driving force, simplifying equipment, and improving equipment utilization rates, ultimately striving for breakthroughs in various industrial production activities.
