"CROXY" is an angular bearing that has enhanced axial rigidity by approximately three times compared to conventional deep groove ball bearings (manufactured by our company). It features high-performance grease that requires no maintenance, sealed with shields on both sides, and allows for the selection of anti-fretting grease (EA7) and cleaning grease (LG2). It is particularly suitable for vertical axis use and contributes to the miniaturization of equipment. 【Features】 ■ Angularized version of the JIS standard 69 series ■ Achieves approximately three times higher rigidity (compared to our products) than deep groove ball bearings ■ Easy installation due to provision with pre-load adjusted combinations ■ Standard precision grade of P5 ■ Contributes to the size reduction of ball screw support sections and the entire equipment *For more details, please refer to the PDF document or feel free to contact us.

"CROXPORT" is a support unit for miniature ball screw supports with a shaft diameter of 3 to 8 mm. It achieves a 60% weight reduction compared to standard market products (compared to MSU-6C), enabling downsizing and lightweighting of equipment, as well as improved responsiveness. By incorporating NSK Micro Precision's miniature thrust angular ball bearings "CROXIE," which are strictly managed for preload, it realizes excellent axial rigidity. [Features] - Enables downsizing of equipment - Achieves excellent axial rigidity - Compared to standard market products, the shaft center height is the same dimension, while the axial load performance is equal to or higher across all models - Available in block type and flange type *For more details, please refer to the PDF document or feel free to contact us.

This product is a super-precision, quiet ball bearing with the same structure as general miniature bearings. It uses stainless steel that is resistant to rust. It meets the international standard "AFBMA ABEC-5 (JIS P5 grade)" for precision, making it suitable for high-precision and miniaturization needs in IT equipment and medical devices. 【Features】 ■ Same structure as general miniature bearings ■ Meets the international standard "AFBMA ABEC-5 (JIS P5 grade)" for precision ■ Uses rust-resistant stainless steel ■ Suitable for high-precision and miniaturization needs in IT equipment and medical devices *For more details, please refer to the PDF document or feel free to contact us.

In June 2020, the Food Sanitation Act was amended, and a positive list system was introduced for synthetic resins that come into direct contact with food. This system involves creating a list of substances for which safety has been confirmed, and, in principle, prohibits the use of any substances not on the list. A transitional measure is in place until May 31, 2025, during which some oil-less products need to be switched over. For more details, please feel free to contact us. 【What is the Positive List System?】 ■ A list of substances for which safety has been confirmed is created ■ The use of substances not on the list is prohibited in principle ■ Usage amounts for additives are also specified ■ Compliance with these regulations contributes to food safety ■ A transitional measure is in place until May 31, 2025 *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce several products that comply with the positive list system of the Food Sanitation Act, which we handle. Starting with "Rutech F," which excels in wear resistance and contributes to reducing the risk of foreign matter contamination, we also offer "Glitron SF," which is suitable for food machinery due to its heat and chemical resistance, and "Fiberfron GH," which is high-strength and can serve as a substitute for metal bearings. Additionally, we have "Glitron F," which has a low static friction coefficient at startup. 【Product Lineup】 ■ Rutech F (filled polyacetal bearing) ■ Glitron SF (filled polyphenylene sulfide bearing) ■ Fiberfron GH (filled polyester bearing) ■ Glitron F (filled polytetrafluoroethylene resin bearing) *For more details, please refer to the PDF document or feel free to contact us.
