Standard adoption of JIS standard 69 series bearings. Resin-wrapped bearings with creep-free inner rings.
The "resin-coated bearing" is a bearing that has a polyacetal resin molded onto the outer ring of a miniature ball bearing. A creep prevention ring is installed on the inner ring of the bearing, enhancing the creep resistance between the inner diameter of the inner ring and the shaft. Additionally, high precision is achieved through machining. The material of the outer ring resin is primarily polyacetal resin, but it can also accommodate other types of resin. 【Features】 ■ A bearing with polyacetal resin molded onto the outer ring of a miniature ball bearing ■ The installation of a creep prevention ring on the inner ring improves creep resistance between the inner diameter of the inner ring and the shaft ■ The outer ring resin's strength is enhanced through insert molding ■ The width of the inner ring is made larger than the outer diameter width to facilitate installation

We have published the features of various types, including pivot ball bearings and grooved thrust ball bearings.
This document introduces "Types and Features of Small Diameter Ball Bearings and Miniature Ball Bearings." Small diameter ball bearings and miniature ball bearings, including precision ball bearings for instruments, can basically be classified into deep groove type and angular type. Typical deep groove bearings include those with an outer ring flange, wide inner rings, thin cross-sections, and specially shaped bearings for synchronization, which are further distinguished by the presence or absence of seals and shields into open type, sealed type, and shielded type. The characteristics of various bearings are illustrated and presented. [Content (partial)] ■ Dimension range of small diameter and miniature ball bearings *For more details, please refer to the PDF document or feel free to contact us.
This introduces information about the raceway of bearings and the materials of rolling elements.
At NSK Micro Precision, we develop, manufacture, sell, and provide services for unit products that combine miniature ball bearings, miniature ball bearings, and precision machined components. The raceway and rolling elements of bearings undergo rolling contact with sliding while repeatedly receiving contact pressure. Therefore, multiple properties are required for the materials of the bearing's raceway and rolling elements. [Properties Required for the Materials of Bearing's Raceway and Rolling Elements] ■ High rolling fatigue strength ■ High hardness ■ High wear resistance ■ Good dimensional stability ■ High mechanical strength ■ Ease of processing ■ Heat and corrosion resistance depending on the application *For more details, please refer to the PDF materials or feel free to contact us.
This introduces the purpose of bearing lubrication and the lubrication methods.
This document explains the "lubrication" of bearings. The purpose of lubricating bearings is to reduce friction and wear inside the bearing and to prevent seizure. The benefits of lubrication include the reduction of friction and wear, extension of fatigue life, removal and cooling of friction heat, and prevention of foreign substances from entering the bearing. There are two lubrication methods: grease lubrication and oil lubrication. The document includes detailed information on these topics and introduces the characteristics of lubricating grease using tables. [Contents (partial)] ■ Purpose of lubrication ■ Lubrication methods *For more details, please refer to the PDF document or feel free to contact us.
It is important to appropriately select the preload amount and preload method according to the application! Introducing preload for bearings.
This document explains the "preload" of bearings. When two bearings capable of receiving axial loads are installed as a pair, and a predetermined axial load F (preload) is always applied, this is referred to as applying preload. Bearings have internal clearances, but by applying preload, this clearance is eliminated, and the balls and raceways make elastic contact. As a result, the bearing is free from play due to clearance, reducing vibrations and noise during rotation, and increasing the rigidity of the bearing.
