Bearing Technical Information: Materials

This introduces information about the raceway of bearings and the materials of rolling elements.

NSK Micro Precision develops, manufactures, sells, and provides services for unit products that combine miniature ball bearings, miniature ball bearings, and precision machined parts. The raceway and rolling elements of the bearing 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 the 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 document or feel free to contact us.

Bearing Technical Information: Preload

It is important to appropriately choose the preload amount and preload method according to the application! An introduction to bearing preload.

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, which reduces vibrations and noise during rotation, and also increases the rigidity of the bearing. [Contents (partial)] ■ Preload methods ■ Magnitude and direction of preload *For more details, please refer to the PDF document or feel free to contact us.

Dry Bearing Dais thermo DTK

High strength with carbon fiber reinforced type! Bearing material that allows for complex shapes through injection molding.

"Daisermo DTK" is a resin solid bearing material made from polyether ether ketone resin, which is a super engineering plastic. By adding carbon fibers and solid lubricants to polyether ether ketone resin, which has high heat resistance among thermoplastic resins, it combines chemical resistance, heat resistance, high strength, and excellent sliding properties. Additionally, it allows for complex shapes through injection molding, and we also offer grades with strength comparable to aluminum alloys. 【Features】 ■ Excellent heat resistance (up to 260°C) ■ High strength with carbon fiber reinforcement ■ Grades with strength comparable to aluminum alloys are also available ■ Excellent chemical resistance ■ Complex shapes possible through injection molding *For more details, please refer to the PDF document or feel free to contact us.

Dry bearing, iron bushing

Can be used in areas other than bearing applications! We also support surface treatments to improve sliding characteristics.

The "iron bushing" is a rolled bushing made from steel or stainless steel that does not contain sliding bearing alloys. It is produced using an environmentally friendly manufacturing method that reduces chips compared to cutting from pipes and improves material yield. It can also be used in areas other than bearing applications and supports surface treatments to improve sliding characteristics. It is suitable for various transportation equipment, production machinery active in various plants, industrial machinery, civil engineering and construction machinery, as well as OA equipment and household electrical products. 【Features】 ■ Improved yield of raw materials ■ Reduction of chips possible ■ Heat treatment and surface treatment available *For more details, please refer to the PDF document or feel free to contact us.
