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.

This introduces the "fit" and "clearance" of bearings.
This document introduces the "fit and clearance" of bearings. The fit conditions for incorporating bearings into equipment are extremely important for fully realizing the performance of the equipment. Additionally, the size of the internal clearance during bearing operation significantly affects the bearing's performance, including fatigue life, vibration, noise, and heat generation. Therefore, it is necessary to select an appropriate radial internal clearance considering the fit, bearing load, rotational speed, and bearing temperature during operation. Furthermore, the document presents information on fits, including the fit between the inner ring and the shaft, as well as the fit between the outer ring and the housing bore, using tables and examples. [Contents (partial)] ■ Fit *For more details, please refer to the PDF document or feel free to contact us.
It introduces the lifespan of bearings, as well as the basic dynamic load ratings and fatigue life.
This document explains the "lifetime of bearings." Even when rolling bearings are used correctly for a specific application, after a certain period of time, they may become unusable due to increased noise and vibration, decreased accuracy from wear, degradation of the lubricating grease, and fatigue of the rolling surfaces. The period until they become unusable is referred to as the broad definition of bearing lifetime, which includes terms such as acoustic lifetime, wear lifetime, grease lifetime, and rolling fatigue lifetime. Additionally, the basic dynamic load rating of bearings and fatigue lifetime are also explained using calculation formulas. [Contents (partial)] ■ Lifetime of bearings ■ Basic dynamic load rating and fatigue lifetime *For more details, please refer to the PDF document or feel free to contact us.
As bearing technical information, we introduce the permissible rotational speed of bearings.
Each bearing has a limit to its rotational speed. When a bearing is operated, as the rotational speed increases, the temperature rise due to frictional heat inside the bearing becomes greater. The limit of rotational speed is an empirical tolerance value that allows the bearing to continue operating without causing seizure or excessive heat generation beyond a certain limit. Therefore, the permissible rotational speed for each bearing varies depending on the type and dimensions of the bearing, the type and material of the cage, the bearing load, the lubrication method, the lubricant, and the cooling conditions surrounding the bearing. [Key Points] - Each bearing has a limit to its rotational speed. - The limit of rotational speed is an empirical tolerance value that allows the bearing to continue operating without causing seizure or excessive heat generation beyond a certain limit. *For more details, please refer to the PDF document or feel free to contact us.*

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.
