World's smallest class mass-produced deep groove ball bearing - Smallest Bearing

World's smallest class mass-produced deep groove ball bearing - Smallest Bearing

Meets international standards AFBMA ABEC-5 / JIS P5 grade precision! The world's smallest class of deep groove ball bearings utilizing precision micro-diameter bearing manufacturing technology.

The "Smallest Bearing" is a component that has been reduced to the extreme limit of the same structure as a standard bearing and features a retainer. It meets the international standard for bearings, "AFBMA ABEC-5 (JIS P5) grade," as a super-precision, silent ball bearing. Previously, the smallest mass-produced bearing from our company had an outer diameter of 4mm, but due to market demand, even smaller bearings with outer diameters of 3.5mm and 2.9mm have recently been developed. 【Features】 ■ Super-precision silent ball bearing ■ Meets the international standard "AFBMA ABEC-5 (JIS P5 grade)" ■ Made from stainless material that is resistant to rust ■ Awarded for outstanding craftsmanship (Modern Master Craftsman) ■ Recipient of the Yellow Ribbon Medal *For more details about the product, please download the PDF materials or contact us.

Miniature ball bearing with flange

Miniature ball bearing with flange

A deep groove ball bearing with a flange and a rim on one side. There is no need to provide a shoulder in the housing inner diameter, allowing for high-precision deep hole machining.

A "flanged bearing" is a deep groove ball bearing with a flange on one side of the outer ring. When using this bearing, there is no need to create a shoulder in the housing's inner diameter, allowing for high-precision through-hole machining. Since the side of the housing serves as the reference for installation, it is necessary to process the perpendicularity of the housing side accurately. 【Features】 ■ Bearing with a flange on one side of the outer ring ■ Can be installed with the side of the housing as the reference ■ No need to create a shoulder in the housing's inner diameter ■ Low-cost products used in office equipment, with various sizes available to suit different applications *For more details about the product, please download the PDF document or contact us.

Inner Creep-Free Resin-Coated Bearing

Inner Creep-Free Resin-Coated Bearing

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
