Additionally, the MF seal adsorbs wear particles generated internally, demonstrating a cleaning effect and further extending the lifespan. 【Features】 ■ Low friction × Dustproof ■ With MF seal ■ Achieves low wear by sealing with point contact ■ Extensive lineup *For more details, please refer to the PDF document or feel free to contact us.
Next-generation ultra-heat-resistant ball bearings with laser cladding.
■Background of Research and Development The maximum operating temperature of commercially available metal ball bearings is approximately 400°C. In higher temperature environments, ceramic ball bearings are used; however, their application is limited due to issues such as impact resistance/strength (load capacity), size constraints, and cost. This research aims to solve existing problems by raising the operating temperature of metal ball bearings from 400°C to 600°C, thereby extending the lifespan of ball bearings, reducing energy consumption due to decreased rotational driving force, simplifying equipment, and improving equipment utilization rates, ultimately striving for breakthroughs in various industrial production activities.

We will introduce MRK's bearings "kingpin" and "valve guide."
Our company manufactures various types of bearings, focusing on thrust ball bearings. The "kingpin" is a pin that connects the knuckle and the front axle, located at the pivot point around which the tires change direction when the steering wheel is turned. It is installed tilted towards the inside of the vehicle, improving maneuverability and reducing shocks from the tires. The kingpin kit includes all the necessary parts for shaft replacement. The "valve guide" is made by placing metal powders such as iron and copper in a mold in a specified ratio, compressing them in a forming machine, and then heating and sintering them at a temperature below the melting point. 【Products Offered】 ○ Kingpin Kit ○ Valve Guide For more details, please contact us or download the catalog.

Four-point contact bearings are mostly standard products from manufacturers, and it is common practice to select products that fit the usage environment of the company and procure products based on their model numbers. Therefore, it is very difficult to procure products that fall outside the manufacturer's standard offerings, and if there is not a certain minimum order quantity, it is challenging to receive support from major manufacturers, making it difficult to produce bearings. In response, our company handles the design and manufacturing of bearing products needed in quantities ranging from hundreds to thousands per month. We specialize in small-diameter and thin-walled bearings, and for thrust ball bearings that achieve a compact height of about 5mm, please leave it to Konishi Seisakusho, which operates "Precision Grinding Processing.com." 【Features of our design and manufacturing support for four-point contact bearings】 ■ While they offer lower rigidity compared to crossed roller bearings, they provide cost advantages. ■ They contribute to space-saving and improved energy efficiency. ■ There are numerous implementation records with major companies, allowing us to provide high-quality products. *For more details, please refer to the related link page or feel free to contact us.
Urakawa bearings are widely used, primarily for automotive bearings.
Automobiles are, in a sense, a collection of rotational movements. Various rotational movements must be able to transmit force to each other smoothly and without loss. For this reason, numerous bearings are used in automobiles. The tapered unit bearing integrates two single-row tapered roller bearings and seals in two types of lubricating grease for long life, making it maintenance-free. This significantly contributes to simplifying the assembly process of automobiles by eliminating the need for gap adjustments during assembly. The angular unit bearing integrates two single-row angular bearings and seals in the necessary lubricating grease for long life, also making it maintenance-free. Compared to the tapered unit bearing, it has a smaller load capacity but is characterized by low torque and low noise. The hub bearing further advances the concept of integration beyond the angular unit bearing by combining even the hub bolts that secure the hubs and wheels, achieving a compact design. This contributes to weight reduction of the suspension and significantly simplifies the assembly process. For more details, please contact us or refer to the catalog.
